Update HISTORY for 9.7.2

Summary:
The write unix time from non L0 files are not surfaced properly because the level's wrapper iterator doesn't have a `write_unix_time` implementation that delegates to the corresponding file. The unit test didn't catch this because it incorrectly destroy the old db and reopen to check write time, instead of just reopen and check. This fix also include a change to support ldb's scan command to get write time for easier debugging.

-# RocksDB Code Generation and Review Guidance
-
-This document provides guidance for generating and reviewing code in the RocksDB project, derived from analysis of code review feedback across hundreds of complex merged Pull Requests. Use this as a reference when writing code with AI assistants or conducting code reviews.
-
----
-
-## General Best Practices
-
-### Code Quality and Maintainability
-
-**Clarity and Readability:** Write clear, self-documenting code. Use meaningful variable names, add comments for complex logic, and structure code to minimize cognitive load. Avoid clever tricks that sacrifice readability for marginal performance gains unless absolutely necessary.
-
-**Consistent Style:** Follow existing code style conventions. RocksDB uses `.clang-format` for formatting, specific naming conventions, and structural patterns. Deviations from these patterns are frequently flagged in reviews.
-
-**Error Handling:** Ensure robust error handling throughout the codebase. Use RocksDB's `Status` type consistently, propagate errors appropriately, and avoid silently ignoring failures. Reviewers pay close attention to edge cases and failure modes.
-
-**Refactoring traps:** At least in production code, avoid constructs that could allow existing code to unexpectedly, quietly change meaning.
-Specifically:
-* Avoid new defaulted parameters. This is the #1 trap on refactoring! (Permitted exception: optional outputs that are generally safe to ignore.)
-* Avoid static_cast, reinterpret_cast, and C-style casts; static_cast_with_check, up_cast, and lossless_cast from cast_util.h are preferred.
-* Avoid declared type `auto` (`auto&`, `auto*` OK).
-
-### Testing Philosophy
-
-**Comprehensive Coverage:** Every change should include appropriate test coverage. This includes unit tests for isolated functionality, integration tests for component interactions, and stress tests for concurrency and performance validation. Reviewers will ask for additional tests if coverage is insufficient.
-
-**Edge Cases and Failure Modes:** Tests should explicitly cover edge cases, boundary conditions, and potential failure scenarios. This is especially important for changes affecting core database operations, compaction, or recovery logic. For non-OK Statuses, prefer comparing code() rather than using ASSERT_TRUE
-which is bad for debugging.
-
-**Platform-Specific Testing:** RocksDB supports multiple platforms (Linux, Windows, macOS) and compilers (GCC, Clang, MSVC). Changes should be tested across relevant platforms, particularly when touching platform-specific code or using compiler-specific features.
-
-### Performance Considerations
-
-**⚠️ PERFORMANCE IS CRITICAL:** RocksDB is a high-performance storage engine where every CPU cycle and memory access matters. When writing code, always evaluate from a performance perspective. This is not optional—performance-aware coding is a fundamental requirement for all contributions.
-
-**Benchmarking and Profiling:** Performance claims should be backed by empirical evidence. Use RocksDB's benchmarking tools (e.g., `db_bench`) to validate improvements. Reviewers will request benchmark results for changes that could impact performance.
-
-**Memory Allocation:** Minimize dynamic memory allocations, especially in hot paths. Prefer stack allocation over heap allocation. Reuse buffers when possible. Consider using arena allocators or memory pools for frequent small allocations. Every `new`, `malloc`, or container resize has a cost.
-
-**Memory Copy:** Avoid unnecessary memory copies. Use move semantics, `std::string_view`, `Slice`, and pass-by-reference where appropriate. Be aware of implicit copies in STL containers and function returns. Prefer in-place operations over copy-and-modify patterns.
-
-**CPU Cache Efficiency:** Design data structures and access patterns to be cache-friendly. Keep frequently accessed data together (data locality). Prefer sequential memory access over random access. Be mindful of cache line sizes (CACHE_LINE_SIZE, typically 64 bytes) and avoid false sharing in concurrent code (see CacheAlignedWrapper). Especially when adding new data members, be mindful of ordering within structs and classes to reduce unnecessary padding (special care with bool members) and avoid larger-than-necessary types (e.g. prefer OptSlice to std::optional<Slice>).
-
-**Loop Optimization:** Look for opportunities to collapse nested loops, reduce loop overhead, and minimize branch mispredictions. Hoist invariant computations out of loops. Consider loop unrolling for tight inner loops. Batch operations when possible to amortize per-operation overhead.
-
-**SIMD and Vectorization:** Leverage SIMD instructions (SSE, AVX) for data-parallel operations when appropriate. Structure data to enable auto-vectorization by the compiler. Consider explicit SIMD intrinsics for critical hot paths like checksum computation, encoding/decoding, and bulk data processing.
-
-**Branch Prediction:** Minimize unpredictable branches in hot paths. Use `LIKELY`/`UNLIKELY` macros to hint branch prediction, e.g. for error cases and other rare or otherwise costly cases, but NOT for predicting popular configurations. Consider branchless alternatives for simple conditionals. Order switch cases and if-else chains by frequency.
-
-**Memory and Resource Management:** Be mindful of memory allocations, especially in hot paths. Use RAII patterns, smart pointers, and RocksDB's memory management utilities appropriately.
-
-**Hot Path Analysis:** When deciding how aggressively to optimize code, consider whether it's on a hot path:
-- **Hot path** (executed thousands+ times, e.g., data access, iteration, compaction loops): Performance is paramount. Apply all optimization techniques—loop collapsing, SIMD, cache optimization, pre-allocation, etc. The cost of each operation is multiplied by execution frequency.
-- **Cold path** (executed rarely, e.g., DB open, configuration parsing, error handling): Maintainability and clarity are more important. Prefer readable code over micro-optimizations. Complex optimizations here add maintenance burden with negligible performance benefit.
-- **Warm path** (moderate frequency): Balance both concerns. Use profiling data to guide optimization decisions.
-
-**Avoid Premature Optimization:** Performance is known critical in places like inner loops of compaction, read path and write path. Elsewhere, try to find a "holy trinity" solution of *correct, simple, and reasonably efficient*. More complex solutions are only appropriate when profiling/benchmarking data shows a measurable payoff.
-
-### API Design and Compatibility
-
-**Backwards Compatibility:** RocksDB maintains strong backwards compatibility guarantees. Breaking changes are rare and require extensive justification. When deprecating features, follow the project's deprecation policy (typically spanning multiple releases).
-
-**Behavioral Compatibility:** Behavior changes are human judgment calls that must be intentional, well-documented (including release notes), and well researched for potential downstream production impact. Agents and reviewers must call out potential gaps, ambiguity, or adverse impacts in intentionality, documentation, and production impact. For an existing accepted input—including an undocumented, discouraged, or historically ignored value—the analysis should compare old and new observable behavior, including performance and resource impact, identify known direct callers and stored configurations, and add or update regression coverage as appropriate.
-
-**API Consistency:** New APIs should be consistent with existing patterns. Use similar naming conventions, parameter ordering, and return types. Reviewers will suggest changes to improve consistency with the broader codebase.
-
-**Documentation:** Public APIs must be thoroughly documented, without unnecessary embelishment nor dwelling on implementation details nor project planning. When non-obvious, include usage examples, parameter descriptions, known bugs or limitations, notes on thread safety, performance characteristics, and compatibility considerations. Re-read comments for ambiguous terminology and phrasing, such as ambiguously re-purposed programming jargon.
-

-
-## Component-Specific Guidance
-
-### Database Core (`db`)
-
-The database core handles write-ahead logging (WAL), memtables, compaction, and recovery. This component receives the most scrutiny in code reviews.
-
-**Concurrency and Thread Safety:** Database operations are highly concurrent. Reviewers carefully examine locking strategies, atomic operations, and memory ordering. Document synchronization assumptions clearly. Use appropriate memory ordering semantics (`acquire`/`release` vs. `seq_cst`).
-
-**Compaction Logic:** Changes to compaction are complex and high-risk. Ensure that compaction logic respects configured parameters, handles edge cases (empty databases, single-file compactions), and maintains correctness under concurrent operations.
-
-**Error Propagation:** Database operations can fail in many ways (I/O errors, corruption, resource exhaustion). Ensure that errors are properly propagated, logged, and handled. Avoid assertions in production code paths.
-
-**Testing:** Database core changes require extensive testing, including unit tests, integration tests, and stress tests. Test with various configurations, compaction styles, and concurrent workloads.
-
-### Public Headers / "Public API" (`include/rocksdb/`)
-
-Public headers define RocksDB's API surface. Changes here have the highest compatibility impact.
-
-**API Design:** New APIs should be intuitive, consistent with existing patterns, and well-documented. Consider how the API will be used in practice and avoid adding unnecessary complexity.
-
-**Backwards Compatibility:** Breaking changes to public APIs require extensive justification and a deprecation plan. Maintain ABI compatibility for bug fixes and patch releases.
-
-**Documentation:** Every public API must be thoroughly documented with usage examples, parameter descriptions, and notes on thread safety and performance characteristics.
-
-**Deprecation:** When deprecating APIs, follow the project's policy. Mark deprecated APIs clearly, provide migration guidance, and maintain support for at least one major release.
-
-### Internal Utilities (`util`)
-
-Internal utilities provide common functionality used throughout the codebase.
-
-**Code Reuse:** Utilities should be general-purpose and reusable. Avoid duplicating functionality that already exists elsewhere in the codebase.
-
-**Error Handling:** Utility functions should handle errors robustly and propagate them appropriately. Consider edge cases like overflow, underflow, and invalid inputs.
-
-**Testing:** Utility functions should have comprehensive test coverage, including edge cases and failure modes. Consider adding death tests for assertions.
-
-**Performance:** Utilities are often used in hot paths. Ensure that implementations are efficient and avoid unnecessary allocations or copies.
-
-### Table Management (`table`)
-
-Table management handles SST file format, block-based tables, and table readers/writers.
-
-**Block Format and Checksums:** Changes to block format require extreme care. Ensure that checksums are computed and verified correctly. Test with various compression algorithms and block sizes.
-
-**Iterator Correctness:** Table iterators are used throughout the codebase. Ensure that iterator semantics (Seek, Next, Prev) are correct, especially at boundaries and with deletions.
-
-**Caching and Prefetching:** Table readers interact with the block cache and prefetching logic. Ensure that cache keys are unique and that prefetching respects configured limits.
-
-**Performance:** Table operations are performance-critical. Benchmark changes that could impact read or write performance.
-
-### Utilities (`utilities`)
-
-Utilities include optional features like transactions, backup engine, and checkpoint.
-
-**Feature Isolation:** Utilities should be self-contained and not introduce unnecessary dependencies on core database internals.
-
-**Deprecation and Cleanup:** Legacy features are being phased out. When removing deprecated code, ensure that migration paths are documented and that users have sufficient warning.
-
-**Cross-Platform Compatibility:** Utilities often interact with OS-specific APIs. Ensure that code works on all supported platforms.
-
-### Options and Configuration (`options`)
-
-Options define RocksDB's configuration system.
-
-**Type Safety:** Use appropriate types for options (e.g., `uint32_t` for flags, scoped enums for enumerated values).
-
-**Deprecation Policy:** When deprecating options, follow the project's policy. Document the deprecation, provide migration guidance, and maintain support for at least one major release.
-
-**Dynamic Configuration:** Some options can be changed dynamically. Ensure that dynamic changes are thread-safe and take effect correctly.
-
-**Validation:** Validate option values and provide clear error messages for invalid configurations.
-
-### Cache (`cache`)
-
-Cache management is critical for RocksDB's performance.
-
-**Concurrency:** Cache operations are highly concurrent. Ensure that implementations are thread-safe and use appropriate synchronization primitives.
-
-**Performance:** Cache operations are in the hot path. Optimize for low latency and high throughput. Benchmark changes carefully.
-
-**Memory Management:** Cache implementations must manage memory carefully to avoid leaks and excessive allocations.
-
-**Eviction Policies:** Changes to eviction policies should be well-tested and benchmarked to ensure they improve overall performance.
-

-
-## Code Review Checklist
-
-When reviewing RocksDB code (or preparing code for review), use this checklist:
-
-### Contract Boundaries
-- [ ] Is each behavior owned by the right layer? High-level policy (for example,
-  "compaction wants this I/O mode") should live at the caller/policy layer, while
-  lower layers should expose generic mechanisms (for example, "open a fresh
-  reader", "skip shared cache insertion", or "use these FileOptions").
-- [ ] Do comments and names describe local contracts rather than leaking a
-  specific caller's rationale into reusable APIs? Generic code should not need to
-  know about one current use case unless the API itself is intentionally
-  use-case-specific.
-- [ ] Does each flag or parameter control one coherent behavior? If one boolean
-  starts implying ownership, cache policy, I/O mode, prefetching, and caller
-  identity, split it into explicit flags or an options struct.
-- [ ] Could a future caller use this lower-level API without accidentally
-  inheriting assumptions from compaction, backup, user reads, or a particular

-## Common Review Feedback Patterns
-
-The following patterns emerged as frequent sources of review feedback:
-
-1. **Test Coverage:** Reviewers frequently request additional tests for edge cases, platform-specific behavior, and failure modes. Complex changes require comprehensive test coverage including unit tests, integration tests, and stress tests.
-
-2. **Error Handling:** Ensure proper error propagation using RocksDB's `Status` type. Avoid silent failures and provide clear error messages that include context about what failed and why.
-
-3. **API Design:** New APIs should be consistent with existing patterns. Use descriptive names that follow established conventions. Avoid breaking changes without strong justification and a clear deprecation plan.
-
-4. **Documentation:** Public APIs must be documented with usage examples and notes on thread safety, performance characteristics, and compatibility considerations. Complex internal logic should also be well-commented.
-
-5. **Performance:** Performance-sensitive changes require benchmark results to validate improvements. Use `db_bench` and other profiling tools to measure impact. Avoid premature optimization that adds complexity without measurable benefit.
-
-6. **Concurrency:** Thread safety is critical in RocksDB. Document synchronization assumptions clearly. Use appropriate memory ordering semantics. Consider potential race conditions and deadlocks.
-
-7. **Code Style:** Follow existing conventions for naming, formatting, and structure. Use `.clang-format` for consistent formatting. Prefer scoped enums (`enum class`) over unscoped enums.
-
-8. **Backwards Compatibility:** RocksDB maintains strong compatibility guarantees. Breaking changes require extensive justification. When deprecating features, provide migration guidance and maintain support across multiple releases.
-
-9. **Refactoring:** Reviewers appreciate refactoring that improves code readability and maintainability. Look for opportunities to deduplicate code and simplify complex logic.
-
-10. **Platform Compatibility:** Ensure changes work correctly on all supported platforms (Linux, Windows, macOS) and with all supported compilers (GCC, Clang, MSVC).
-
-11. **Contract Boundary Leaks:** When a change plumbs a new option or use-case
-specific behavior through multiple subsystems, review the call chain for
-contract leaks. Caller-specific rationale belongs at the call site or public API
-documentation; reusable layers should expose precise, layer-local capabilities.
-Watch especially for comments mentioning one caller in generic code, booleans
-that silently bundle several behaviors, and downstream code inferring policy
-from an implementation detail instead of an explicit option.
-

-
-## Important tips
-
-### Pull request and diff summaries
-* Before writing or updating an external RocksDB pull request summary or its
-  corresponding internal Phabricator diff summary, read and follow
-  `claude_md/pull_request_summary_guideline.md`.
-
-### Build system
-* There are 3 build system. Make for git clones, BUCK (meta internal) for hg
-  clones, and CMake for some special cases.
-* When a new .cc file is added, update Makefile, CMakeLists.txt, src.mk, BUCK.
-* Don't manually edit BUCK file, after updating src.mk, run
-    /usr/local/bin/python3 buckifier/buckify_rocksdb.py to update it
-* For -j in make command, use the number of CPU cores to decide it.
-* When searching for references to something (a symbol, library, etc.), do not
-  restrict or truncate your search based on presumed relevance or scope. It is
-  important and time-saving to keep the repo reasonably consistent across
-  different build systems, programming languages, and even between
-  documentation and implementation.
-
-### Avoiding mixed build modes with Make (use `AUTO_CLEAN=1`)
-
-Object files are written to the same paths regardless of build flags, so
-reusing objects from a prior build with different flags causes confusing
-linker errors, etc. This problem is essentially avoidable by ALWAYS using
-`AUTO_CLEAN=1 make -j<n> <something>` for manual make invocations. This
-will automatically clean object files if the build parameters/flavor have
-changed. The `build_tools/rockstest.sh` / `rocksptest.sh` helpers described
-below set `AUTO_CLEAN=1` for you.
-
-`AUTO_CLEAN=1` does not fix Make failures associated with stale .d files
-referring to removed files. Resolve that manually or with `make clean`
-without complaining to the user.
-
-### Source checks
-* Run `make check-sources` before committing. This catches non-ASCII
-    characters in source files and other source-level issues that CI will
-    reject. In particular, **do not use Unicode characters** (em dashes,
-    smart quotes, etc.) in comments or strings -- use ASCII equivalents
-    (`--` instead of em dash, `'` instead of smart quote, etc.).
-
-### License headers
-* Every new source file needs a license header. For a file that does **not**
-    carry an outside/third-party copyright, use the standard Meta dual-licensed
-    header (the dual-license designation is required -- a bare
-    "All Rights Reserved" copyright is not an acceptable open-source header):
-    ```
-    //  Copyright (c) Meta Platforms, Inc. and affiliates.
-    //  This source code is licensed under both the GPLv2 (found in the
-    //  COPYING file in the root directory) and Apache 2.0 License
-    //  (found in the LICENSE.Apache file in the root directory).
-    ```
-    Use a `#` comment prefix instead of `//` for shell, Python, and Makefile
-    fragments.
-* Files derived from an external source (e.g. LevelDB) keep their original
-    upstream copyright line in addition to the header above.
-
-### RTTI and dynamic_cast
-* Production code and `db_stress` must build in **release mode
-    (`-fno-rtti`)**. Do not use `dynamic_cast` anywhere except unit tests.
-    Use `static_cast_with_check` from `util/cast_util.h` (validates with
-    `dynamic_cast` in debug builds, plain `static_cast` in release).
-* Unit tests (`*_test.cc`) are built in debug mode with RTTI enabled.
-
-### Cross-platform / portability
-Local `make` only exercises Linux with GCC/Clang, but CI
-(`.github/workflows/pr-jobs.yml` and `nightly.yml`) gates on a much wider
-matrix, so portability breaks are invisible locally until CI fails. Code must
-build (and where noted, run tests) across:
-
-| Axis | Must support |
-|------|--------------|
-| OS | Linux (x86_64 + ARM), macOS, Windows |
-| Architecture | Little-endian and big-endian targets, including Linux on s390x |
-| Compiler | GCC, Clang (libstdc++ **and** libc++), AppleClang, **MSVC (VS2022)**, MinGW (Linux cross-compile, build-only, no gflags) |
-| Build system | Make, CMake, and BUCK (internal) -- keep all in sync (see "Build system" above) |
-| Config | release (`-fno-rtti`), `ASSERT_STATUS_CHECKED`, ASAN/UBSAN/TSAN, folly, unity build, JNI/Java |
-
-Treat these as constraints to satisfy and infer the specifics from them before
-adding any system header, libc call, or compiler-specific construct. The most
-common trap: anything that compiles under GCC/Clang on Linux but not under
-**MSVC/MinGW** -- e.g. unguarded POSIX-only headers/functions (`<unistd.h>`,
-`<sys/*.h>`, `getpid`, `_exit`, ...) or GCC/Clang extensions
-(`__attribute__`, `__builtin_*`, VLAs, `alloca`). Prefer the `port::`/`Env`
-abstractions; otherwise guard with `#ifdef OS_WIN` (POSIX `<unistd.h>` ->
-Windows `<process.h>`). Because libc++ is also tested, include what you use
-rather than relying on libstdc++ transitive includes.
-
-Do not use `static_assert` to reject a supported architecture for an optional
-feature. Check an existing `port::` capability such as `port::kLittleEndian`
-and disable only the unsupported feature so the rest of RocksDB still builds.
-Use a portable representation when the feature itself must work across
-architectures.
-
-### Unit Test
-* After all of the unit tests are added, review them and try to extract common
-    reusable utility functions to reduce code duplication due to copy past between
-    unit tests. This should be done every time unit test is updated.
-* Don't use sleep to wait for certain events to happen. This will cause test to
-    be flaky. Instead, use sync point to synchronize thread progress.
-* Cap unit test execution with 60 seconds timeout.
-* To build and run unit tests locally, prefer these helper scripts:
-    * `build_tools/rocksptest.sh <test_binary> [more_binaries...] [args...]`
-        builds the binary(ies) with parallel make and `AUTO_CLEAN=1` and runs
-        them under gtest-parallel, sharding the test cases across CPUs. Prefer
-        this whenever running more than a couple of test cases, e.g.
-        `build_tools/rocksptest.sh table_test` or
-        `build_tools/rocksptest.sh db_test env_test --gtest_filter=*Foo*`.
-    * `build_tools/rockstest.sh <test_binary> [args...]` builds with parallel
-        make and `AUTO_CLEAN=1` and runs the binary directly (serially).
-        Use it only for a very small number of test cases, e.g.
-        `build_tools/rockstest.sh db_test --gtest_filter=*MixedSlowdown*`.
-* After writing a test, stress-test for flakiness (AUTO_CLEAN handles the
-    rebuild needed by the `COERCE_CONTEXT_SWITCH=1` flag change):
-    ```bash
-    COERCE_CONTEXT_SWITCH=1 build_tools/rockstest.sh {test_binary} -r100 \
-        --gtest_filter="*YourTestName*"
-    ```
-* For CI-style flaky tests that do not reproduce with `gtest_parallel.py`,
-    `--gtest_repeat`, or normal coerce-mode runs, inspect
-    `tools/gtest_parallel_repro.py --help`.
-* Each unit test file has overheads, so avoid creating new unit test files
-  for random minor features. Consider adding to slice_test, db_etc3_test, or
-  others.
-
-### Unit test dedup guidelines
-* Extract helper functions for repeated patterns such as object
-    construction, round-trip (encode → decode → verify), and common
-    assertion sequences.
-* Use table-driven tests (struct array + loop) when multiple test cases
-    share the same logic but differ only in input/expected data.
-* Prefer randomized tests over exhaustive parameter permutations. Use
-    `Random` from `util/random.h` (not `std::mt19937`). Use a time-based
-    seed with `SCOPED_TRACE("seed=" + std::to_string(seed))` so failures
-    are reproducible.
-* Keep deterministic edge-case tests separate from randomized tests
-    (error paths, boundary conditions, format verification).
-* Methods only used in tests should be private with `friend class` +
-    `TEST_F` fixture wrappers. In wrappers, always fully qualify the
-    target method to avoid infinite recursion.
-
-### Adding new public API
-    Refer to claude_md/add_public_api.md
-
-### Changing existing public API behavior
-    Follow the Behavioral Compatibility requirements above.
-
-### Adding new option
-    Refer to claude_md/add_option.md
-
-### Removing deprecated option
-    Refer to claude_md/remove_option.md
-
-### Metrics
-* When adding a new feature, evaluate whether there is opportunity to add
-    metrics. Try to avoid causing performance regression on hot path when adding
-    metrics.
-
-### Stress test
-* When adding a new feature, make sure stress test covers the new option.
-
-### Component docs
-* For component-level design notes and implementation walkthroughs, start with
-    `docs/components/index.md`.
-* Documentation under `docs/components/` is organized by subsystem in
-    `docs/components/<area>/`.
-* Each subsystem directory should have an `index.md` entry point plus focused
-    chapter files for deeper topics.
-
-### DB bench update
-* When adding a performance related feature, support it in db_bench
-
-### Adding release note
-* Release note should be kept short at high level for external user consumption.
-    Release notes identify what users might care about most in a release. They
-    are not exhaustive and are not a guide. PLEASE learn from past agents who
-    tried to build elaborate release notes with implementation details and
-    elsewhere-documented nuance. That wastes time. Fight the bias that
-    "my change" is important so must be worthy of release note mention.
-* If more than single markdown line, consider how their formatting will be
-    integrated into HISTORY.md.
-
-### Blog posts (docs/_posts)
-* Blog post authors must be defined in `docs/_data/authors.yml` to be displayed
-
-### Final verification of the change
-* Execute `AUTO_CLEAN=1 make check` to build all of the changes and execute all
-    of the tests. `AUTO_CLEAN=1` ensures a clean rebuild if your previous build
-    used different parameters. Note that executing all of the tests could take
-    multiple minutes.
-* Run `AUTO_CLEAN=1 ASSERT_STATUS_CHECKED=1 make check` to verify all Status
-    objects are properly checked. This catches missing error handling that can
-    lead to silent data corruption. Merely building with ASSERT_STATUS_CHECKED=1
-    accomplishes nothing; it enables a runtime check. New unit tests missing
-    Status checks is a common failure point, even from agents. Avoid new uses
-    of PermitUncheckedError(). That's the lazy solution.
-
-### Monitoring make check progress
-* Use `make check-progress` to get machine-parseable JSON progress while
-    `make check` is running. This is useful for Claude Code to monitor long
-    builds without timeout issues.
-* Run `make check` in background, then poll progress:
-    ```bash
-    AUTO_CLEAN=1 make check &
-    # Poll periodically:
-    make check-progress
-    ```
-* The output shows current phase and progress:
-    ```json
-    {"status":"running","phase":"compiling","completed":300,"total":919,...}
-    {"status":"running","phase":"testing","completed":1500,"total":29962,"failed":0,"percent":5,...}
-    {"status":"completed","phase":"testing","completed":29962,"total":29962,"failed":0,"percent":100,...}
-    ```
-* Phases: `compiling` -> `linking` -> `generating` -> `testing` -> `completed`
-* Key fields: `status`, `phase`, `completed`, `total`, `failed`, `percent`
-* When tests fail, `failed_tests` array shows details (up to 10 failures):
-    ```json
-    {"status":"running",...,"failed":3,"failed_tests":[
-      {"test":"cache_test-CacheTest.Usage","exit_code":1,"signal":0,"output":"...test log..."},
-      {"test":"env_test-EnvTest.Open","exit_code":0,"signal":11,"output":"...Segmentation fault..."}
-    ]}
-    ```
-* `exit_code`: non-zero means test assertion failed
-* `signal`: non-zero means test was killed (e.g., 9=SIGKILL, 6=SIGABRT, 11=SIGSEGV)
-* `output`: last 50 lines of test log including error messages and stack traces
-
-### Executing benchmark using db_bench
-* Since the goal is to measure performance, we need to build a release binary
-    using `AUTO_CLEAN=1 DEBUG_LEVEL=0 make db_bench`. If there is an engine
-    crash due to a bug, switch back to a debug build with
-    `AUTO_CLEAN=1 make dbg`; `AUTO_CLEAN=1` handles the release<->debug rebuild
-    automatically.
-
-### Formatting code
-* After making change, use `make format-auto` to auto-apply formatting without
-    interactive prompts (Claude Code friendly).

 # Rocksdb Change Log
 > NOTE: Entries for next release do not go here. Follow instructions in `unreleased_history/README.txt`
 
-## 11.14.0 (11/05/2026)
-### New Features
-* Added experimental `SetAsyncReadCPUTimeEnabled()`: the next async or coroutine read started on the thread records its CPU time in `PerfContext::get_cpu_nanos` at any perf level except `kDisable`, without turning on the other timers of `kEnableTimeAndCPUTimeExceptForMutex`.
-* Added `SplitDB()`, `DeleteSplitRanges()`, and `MergeDB()` in `rocksdb/utilities/db_split_merge.h`, plus a `db_split_merge` command-line tool, for moving selected column-family key ranges into a new DB and copying ranges into existing column families.
-* Added opt-in sampled logging of long-held DB-wide mutexes under `StatsLevel::kAll`, with a runtime-changeable `mutex_hold_log_threshold_us` DB option defaulting to 0 (disabled).
-* Add experimental live tuning of a DB's options (`StartLiveTuneCycle()`, `GetLiveTuneStatus()`, `StopLiveTuneCycle()` in `include/rocksdb/live_tune.h`): one call runs a cycle that measures the DB, asks an application-provided `LiveTuneAdvisor` for option changes, applies them, and reverts them when they break the application's constraints or do not prove better.
-* Added `CompactionFilter::GetMergeOrder()` and `CompactionFilterFactory::GetMergeOrder()` to optionally run the merge operator before the compaction filter during compaction, so that the filter sees merge results. The default behavior is unchanged.
-* Parallel compression (`CompressionOptions::parallel_threads > 1`) now works with a `user_defined_index_factory` whose builders support it, including the built-in trie index. Previously a custom index always forced single-threaded compression.
-* Added option `reject_too_old_file` to `IngestExternalFileOptions` and `ImportColumnFamilyOptions` to reject files whose data is already older than the column family's `periodic_compaction_seconds` (or `ttl` for FIFO compaction).
-* Added BlobDB support for remote compaction. Blob garbage collection uses the
-cutoff computed by the primary; workers receiving legacy input without a cutoff
-safely disable blob garbage collection for that job. When the primary rejects a
-remote blob result because its metadata, files, or capabilities fail validation,
-it reruns the compaction locally, so `CompactRange` and `CompactFiles` succeed.
-`CompactionService` `kFailure` semantics are unchanged; ZippyDB production also
-maps service failures to local fallback through `HandleFailure(FALLBACK_LOCAL)`.
-* `CompactRangeOptions::skip_missing_blob_files` enables offline repair that deletes values referencing integrated external blob files absent from Version metadata, preserves available wide entity columns, and rewrites selected SSTs locally, bypassing `DBOptions::compaction_service`. It defaults to false; FIFO compaction and legacy BlobDB are unsupported.
-* Added `db_ownership_start_time` and `data_file_provenance` (decoded by `DataFileProvenance`) to `SstFileMetaData`, recording when the DB began holding each SST file and how it got the file (e.g. flush, compaction, ingestion, or import).
-* Added `TableFactory::IsTableBuilderSupported()` and `ExternalTableFactory::IsTableBuilderSupported()` for table factories that only read ingested or imported files. A column family whose factory returns false must set `disallow_memtable_writes`, is never scheduled for automatic compaction, does not stall writes for L0 files or pending compaction bytes, and returns `NotSupported` from `CompactRange()` and `CompactFiles()` instead of failing a background compaction.
-* trace_analyzer: new `--analyze_put_entity` flag analyzes PutEntity queries (previously their statistics were neither enabled nor disabled explicitly).
-* Added `TraceOptions::include_read_write_options`: query traces can record the main `ReadOptions` and `WriteOptions` of each traced call (e.g. `fill_cache`, `disableWAL`), which replay then uses instead of default options.
-
-### Public API Changes
-* Added `GetEncodedEntrySize()` and an `EncodeEntry()` overload that writes internal keys into caller-owned buffers without allocating on success.
-* Added `Env::Priority::READ` and `ThreadStatus::READ_PRIORITY` for a dedicated Env-managed read-work thread pool. `Env::Priority::USER` remains reserved for internal statistics and is not backed by a thread pool.
-* Added experimental `MultiScanArgs::use_parallel_async_io_block_decompression` for materializing asynchronously prefetched data blocks, including decompression, in parallel on the `Env::Priority::READ` thread pool. A zero-sized pool preserves inline materialization.
-* Added the experimental `IndexFactory` interface (`include/rocksdb/index_factory.h`) for pluggable SST indexes; the `UserDefinedIndex*` names remain as aliases. `BlockBasedTableOptions::index_mode` chooses which indexes an SST is built with and which one reads use by default, superseding the now-deprecated `use_udi_as_primary_index` and `fail_if_no_udi_on_open`. `ReadOptions::read_index` overrides that choice per read, and the `standard_index_is_stub` table property marks SSTs built with `kCustomOnly`. Both options are also available in the C API.
-* Added experimental `DB::GetEntityWithMetadata()` and `DB::MultiGetEntityWithMetadata()`, the wide-column entity counterparts of `DB::GetWithMetadata()` and `DB::MultiGetWithMetadata()` with opt-in explicit-snapshot newer-version detection. Requesting key timestamps returns `NotSupported`.
-* Removed support for building on Solaris, which had not compiled since 5.18. Removed RocksJava `Environment.isSolaris()`.
-
-### Behavior Changes
-* With `ReadOptions::async_io`, `MultiGet` now reads data blocks of direct-IO files with asynchronous reads (`FSRandomAccessFile::ReadAsync`) instead of a synchronous `MultiRead`. Each block read is aligned separately rather than merged with adjacent reads. The bytes read are still charged to `DBOptions::rate_limiter` at `ReadOptions::rate_limiter_priority`.
-* Asynchronous file reads (`FSRandomAccessFile::ReadAsync`, used with `ReadOptions::async_io` by `MultiGet` and iterator prefetching) are now charged to `DBOptions::rate_limiter` at `ReadOptions::rate_limiter_priority`, like synchronous reads. A read is charged once the file system accepts it.
-* `CreateColumnFamily()` and `CreateColumnFamilies()` now run the table factory option validation that `DB::Open()` runs, so they return `InvalidArgument` instead of creating a column family that the next `DB::Open()` would reject. External table factories wrapped by `NewExternalTableFactory()` now receive `ValidateOptions()` calls.
-* With `CompactionOptionsFIFO::allow_trivial_copy_when_change_temperature`, each file copied for a temperature change is now reported to `EventListener::OnTableFileCreationStarted()` and `OnTableFileCreated()` (with the original file's table properties) and included in `CompactionJobInfo::table_properties`.
-* `DB::GetMergeOperands()` now resets only the `merge_operands` entries it fills, instead of all `expected_max_number_of_operands` entries. Entries past `*number_of_operands`, and the whole array on a non-OK result, are left as the caller passed them.
-* The JSON written to the info LOG by `EventLogger` (`EVENT_LOG_v1` lines) and by `VersionEdit::DebugJSON()` now escapes special characters in keys and string values, and writes non-finite floating-point values as `null`, so the output is always valid JSON.
-* Improved how `periodic_compaction_phase_recovery_percent` spreads catch-up periodic compactions after it is enabled or changed (or the DB is reopened). This reduces a transient burst in periodic compactions when many DBs make such a change at once.
-* The new DB option `use_separate_remote_compaction_pool` defaults to false and can be changed through `SetDBOptions()` for newly scheduled jobs. When enabled with CompactionService, remote jobs use a dedicated pool and each local subcompaction uses LOW/BOTTOM and counts against the DB compaction limit. Existing jobs finish using their original scheduling model.
-* `DB::SetOptions()` now returns OK without writing a new OPTIONS file or installing a new SuperVersion when the call changes no option value, as `DB::SetDBOptions()` already does. Calls that set an object option, such as `table_factory` or one of its fields, are still applied in full. After a failed OPTIONS file write, the next `SetOptions()` or `SetDBOptions()` call writes the file even if no option value changes.
-* Custom index factories are rejected with user-defined timestamps in every index mode except `kStandardOnly`, which ignores the factory. Custom-index block-cache hits, misses, and adds now contribute to `BLOCK_CACHE_INDEX_*` instead of `BLOCK_CACHE_DATA_*`.
-Trie index construction returns `NotSupported` when a data-block offset or size exceeds `UINT32_MAX`, including when the trie is optional in `kStandardDefault`. Flush, compaction, and `SstFileWriter::Finish()` can therefore fail for such output; an SST larger than 4 GiB is not itself the rejection condition. File-size targets do not split L0 outputs or `SstFileWriter` outputs. Bound those outputs or disable trie construction with `kStandardOnly`.
-
+## 9.7.2 (10/08/2024)
 ### Bug Fixes
-* Fixed a race where `IngestExternalFiles()` with `atomic_replace_range` could delete an existing SST file that a concurrently picked compaction (e.g. a universal compaction outputting to L0) used as input, causing the compaction to fail with "Corruption: VersionBuilder: Cannot delete table file ... since it is not in the LSM tree" and putting the DB into read-only mode. Atomic range replacement now returns `NotSupported` with FIFO compaction.
-* Fixed blob direct write when sealing a blob file fails during a flush or a write: the flush left its memtables marked as being flushed, so no later flush picked them up and error recovery waited for them forever, and the blob file was dropped from tracking, so a retried flush could install table files whose blob file was never added to the MANIFEST.
-* Fixed blob direct write with more than one concurrent flush of a column family: a later flush sealed and published the blob files of the oldest pending memtable instead of its own, so flushes failed with `Corruption: VersionBuilder: Blob file #N already added` and the database stopped.
-* Fixed blob direct write when the `SstFileManager` space limit is reached while a blob file is sealed: the sealed blob file was deleted while memtables still referenced it, so reads of its values failed and the values were lost, and reporting the error could deadlock with a concurrent memtable switch. The seal and the write or flush now succeed and keep the file, and writes then stop with a `SpaceLimit` background error, so for blob direct write the limit is soft: usage can exceed it by up to about `blob_file_size` × `blob_direct_write_partitions` for each memtable not flushed yet. Also fixed a write batch that failed after writing some of its values to blob files: those blobs are now counted as garbage, so their blob file can still be deleted.
-* Values that retain external blob references now keep their original timestamps during history compaction, preventing blob key verification failures.
-* Fixed `DB::ClipColumnFamily()` leaving an empty-string key outside the kept range when it is the only key in an L0 SST file.
-* Fixed `format_version=8` with `ReverseBytewiseComparator`: a block's stored common key prefix could extend past a user key (one following longer user keys that extend it), so reads and iteration could miss that key (or its deletion, exposing an older value), and compactions could fail with `Corruption`. Files written by affected versions (11.10 through 11.13) are now read correctly, and new files no longer have this problem.
-* Fixed SST file times that could defer periodic compaction and TTL. Files written by `SstFileWriter`, flushed during WAL recovery, or recovered by `RepairDB` now record a file creation time. Files added by `IngestExternalFile()` or `CreateColumnFamilyWithImport()` now keep the creation and oldest ancestor times from the file or export metadata (capped at the current time) instead of taking the time they were added, so ingesting or importing old data can make it due for periodic compaction or TTL soon afterward. FIFO TTL compaction now also deletes ingested `SstFileWriter` files, which previously blocked TTL deletion of themselves and all newer files. Files copied by FIFO compaction for a temperature change now keep the original file's creation time.
-* Fixed a debug-build assertion failure and incorrect cache charge and block-cache byte statistics in release builds when a full, strict-capacity LRU cache with metadata charging creates an uncharged standalone handle, including during secondary-cache promotion.
-* Fixed atomic flushes of all column families when another column family is dropped while they wait: `CompactRange()` no longer fails with a "Column family dropped" error, and `WaitForCompact()` and DB close no longer return OK without flushing the remaining column families.
-* Fixed a bug where MemPurge returned with the DB mutex unlocked when the compaction filter created for flush did not ignore snapshots.
-* Fixed a crash in MultiScan `Iterator::Prepare()` with a single scan range without a limit when the DB has L0 files, and an assertion failure in debug builds when `Prepare()` is called on an already-positioned iterator. `Prepare()` now leaves the iterator invalid until it is positioned again (e.g. by `Seek()`).
-* Fixed `MultiGet` returning NotFound for existing keys that are outside the prefix extractor's domain, with partitioned filters, `whole_key_filtering=false`, and filter partitions cut together with index partitions (`decouple_partitioned_filters=false`, also the layout of files written by older versions). A filter partition holding only such keys is empty, and `MultiGet` treated every key mapped to it as absent. `Get` was not affected.
-* Fixed prepared external file ingestions retaining unrelated obsolete SSTs until commit or abort. Prepared ingestions now protect only their staged files from deletion.
-* Fixed data loss with `min_tombstones_for_range_conversion` and external file ingestion. An iterator whose view predated the ingestion could convert the deleted keys around the ingested keys into a range tombstone that deleted them. This happened when the file got no new sequence number (sequence number zero, `ingest_behind`, or `allow_db_generated_files`), and when an iterator was created during the ingestion.
-* Fixed a data loss bug where an iterator with `ReadOptions::read_tier = kMemtableTier` could, with `min_tombstones_for_range_conversion` enabled, insert a range tombstone that deleted live keys stored only in SST files. Read-path range tombstone conversion now runs only for iterators with `read_tier = kReadAllTier`.
-* Fixed a race with `recycle_log_file_num > 0` where an obsolete WAL could be reused for a new WAL while its old writer was still open. Closing the old writer then truncated the reused file to the old WAL's size, so writes in the new WAL past that point, including acknowledged `sync` writes, were lost on the next reopen.
-* Fixed remote compaction ignoring `preclude_last_level_data_seconds` and `preserve_internal_time_seconds`, which caused recent data to be written to the last level and recent sequence numbers to be zeroed. Takes effect once both the primary and the compaction worker are upgraded.
-* Fixed `DB::OpenAndCompact()` with `OpenAndCompactOptions::allow_resumption` not calling `EventListener::OnSubcompactionCompleted()` when the compaction fails to resume from its saved progress.
-* Fixed MANIFEST catch-up on secondary instances (`TryCatchUpWithPrimary()`) and follower instances installing a column family with no files and still returning OK. This happened when catch-up switched to a new MANIFEST and the primary deleted a file that MANIFEST lists before catch-up checked it, recording the deletion in a newer MANIFEST. Catch-up now keeps the column family's previous view until a complete state from the new MANIFEST is available.
-* Custom index blocks now reuse cached contents on SST reopen, and deprecated UDI boolean options can be cleared without overriding an explicitly configured index mode.
-Legacy UDI options copied from a factory can now be cleared before constructing a new factory without retaining the derived mode. The C API preserves both that rollback behavior and explicitly selected modes. OPTIONS files serialize equivalent legacy booleans for `kStandardDefault`, `kStandardRequired`, and `kCustomDefault` so older readers retain routing.
-Empty custom-index output retains the standard-index fallback in modes that write both indexes; custom-only output must remain nonempty. Default primary reads retain the table factory's precedence over a legacy per-read factory pointer, while explicit custom selectors still check its name.
-* Preserve legacy UDI routing when loading old OPTIONS files, and reject invalid index modes in standalone SST readers and writers. Table readers now charge the custom index blocks they own; a custom reader whose `ApproximateMemoryUsage()` already includes that block should override `IndexFactoryReader::MemoryUsageIncludesIndexBlock()` to return true so the block is not charged twice.
-Keep cached custom-index Slice views intact when a reader consumes its input. Register custom-index cache helpers without requiring a later change. Trie index size estimates now account for shared prefixes, preventing premature compaction file cuts, and reject data-block offsets or sizes exceeding the 32-bit on-disk limit instead of truncating them.
-
-### Performance Improvements
-* With `ReadOptions::pin_data`, iterators over read-only DBs opened with `max_open_files = -1` and `allow_mmap_reads = true` no longer accumulate memory as they move across SST files.
-* On a read-write primary, `DB::GetSnapshot()` and `DB::ReleaseSnapshot()` no longer acquire the DB mutex in the common case. Secondary and follower snapshot creation retains the DB mutex needed to synchronize with view installation, while release remains sharded. The snapshot list is now split into 16 per-CPU shards, each with its own lock, so primary threads creating and releasing snapshots no longer serialize on one lock or wait behind flush, compaction, or other work holding the DB mutex. Snapshot-release maintenance is deferred to existing flush, compaction, and periodic maintenance paths. Primary snapshot creation serializes with the DB-mutex-held phases of external file ingestion but can proceed while the MANIFEST write temporarily releases that mutex.
-
-
-## 11.13.0 (10/21/2026)
-### New Features
-* Added `FileSystem::IsPreallocationSupported()`. A `FileSystem` that never preallocates file space can return false so that DB open skips reopening and truncating the last WAL file.
-
-### Public API Changes
-* Added the experimental `DBOptions::track_options_file_number_in_manifest`
-rollout option (with C and Java bindings). The option is persisted in each
-OPTIONS file. When enabled, RocksDB durably creates an OPTIONS file and then
-commits its file number in MANIFEST. Column-family create/drop commits the
-configuration snapshot and membership in one MANIFEST record. A newer tracked
-OPTIONS file without a commit is ignored after a crash, while a newer OPTIONS
-file written with tracking disabled retains the legacy highest-numbered-file
-behavior. Batched column-family changes publish one snapshot; after partial
-success it can be a safe superset that persisted-options APIs filter against
-live MANIFEST membership. Ordinary `DB::Open` continues to use caller-supplied
-options and does not depend on the operational snapshot.
-* Added `EncodeEntry()`, `PackSequenceAndType()`, and `UnPackSequenceAndType()` in `rocksdb/utilities/types_util.h` to construct internal keys and pack or unpack their sequence numbers and entry types. `kInternalKeyFooterSize` exposes the footer size in bytes.
-* Added `ldb update_manifest --rebind_options_file --options_file=OPTIONS-<number>` for offline repair of a committed MANIFEST OPTIONS file number. Operators must select a trusted snapshot that has MANIFEST tracking enabled and provide any external DB/CF allocation roots that are not serialized in OPTIONS.
-
-### Behavior Changes
-* With `max_bgerror_resume_count <= 0` (auto resume disabled), a retryable or file-scoped IO error during compaction or flush is now a hard background error that stops writes until `DB::Resume()` is called. Previously, compaction errors were silently retried, and flush errors with a healthy WAL were soft errors that let writes continue while flushes were stopped.
+* Fix a bug for surfacing write unix time: `Iterator::GetProperty("rocksdb.iterator.write-time")` for non-L0 files.
 
+## 9.7.1 (09/26/2024)
 ### Bug Fixes
-* Fixed two more `SstFileManager` trash accounting leaks: retrying a failed trash deletion immediately (for example with rate limiting disabled) after the file had disappeared, and a trash file that was deleted but whose directory sync then failed. In both cases the file's size stayed in the total trash size and tracked size until restart.
-* Fixed `SstFileManager` trash accounting leaking the size of a queued trash file that disappeared before deletion (for example because its directory was renamed). The leaked bytes stayed in the total trash size until restart, which could push every later deletion past `max_trash_db_ratio` and make it immediate instead of rate limited.
-* Fixed `MultiGet` with `ReadOptions::async_io` returning `NotSupported` when io_uring initialization or an asynchronous read submission fails. It now checks async I/O support on the reading thread and falls back to synchronous reads when needed.
-* Fixed subset checkpoints so their newest OPTIONS file lists only the column
-families retained by the checkpoint. This applies with both legacy
-highest-numbered OPTIONS selection and MANIFEST-tracked OPTIONS selection, and
-prevents `LoadLatestOptions` from recreating column families that the subset
-checkpoint intentionally dropped from its copied MANIFEST.
-
-### Performance Improvements
-* Perf context counters and timers no longer call the thread-local init function of `perf_context` on every update. With `kEnableCount`, a counter update costs about 60% less.
-
-
-## 11.12.0 (10/07/2026)
-### New Features
-* Added `FullExternalTableFactory` and related full-mode external table APIs that preserve RocksDB internal keys, enabling external tables to support nonzero sequence numbers, point and single deletions, merge operands, blob indexes, wide-column entities, snapshots, live DB writes, and multi-level compactions.
-
-### Public API Changes
-* Added experimental coroutine capability interfaces for basic and full `ExternalTableReader` implementations. Coroutine-capable external readers can initiate file reads through `FSRandomAccessFile::SubmitReadAsync()`.
-* `ExternalTableFactory::NewTableReader()` now receives an already-opened `FSRandomAccessFile` and its file size instead of requiring implementations to reopen `file_path`. The supplied file preserves RocksDB's direct-I/O alignment handling, rate limiting, read statistics and listener notifications, prefetching, and synchronous, asynchronous, and batched reads.
-* Added `PutRangeDeletionBlock()`, `GetRangeDeletionBlock()`, and `IsDeleteRangeSupported()` to the external table interfaces so formats can opt in to range deletions using RocksDB's raw range-deletion metadata block.
-* Opaque `PreparedFileInfo` metadata can now be serialized to a checksummed representation with `SerializePreparedFileInfo()` and restored with `DeserializePreparedFileInfo()` for reuse across processes.
-* Removed the deprecated `IngestExternalFileOptions::write_global_seqno` option and its C, Java, and `ldb` APIs, `TableProperties::external_sst_file_global_seqno_offset`, and the `file_offset` output from `ExternalTableReader::GetPropertiesBlock()`. Existing external SST files whose global sequence number was rewritten without updating the properties-block checksum remain readable.
-* `TablePropertiesNames` has no apparent use in the public API so has been deprecated there.
-* `TableProperties::creation_time` is renamed to `oldest_ancestor_time`, which better describes its meaning, along with `TablePropertiesNames::kCreationTime` to `kOldestAncestorTime`. The misspelled `SstFileMetaData::oldest_ancester_time` is renamed to `oldest_ancestor_time`. The old names remain available as deprecated aliases and will be removed in a future release.
-* Added `WriteBufferFlushPolicy` and `WriteBufferManager` policy selection for flushing the oldest or largest column family, including configurable batched flushing of the largest column families across DBs sharing a manager, with C and Java bindings.
-
-### Behavior Changes
-* When `ExternalTableBuilderBase::PutPropertiesBlock()` returns `NotSupported`, RocksDB now overrides `num_entries`, `raw_key_size`, and `raw_value_size` from `ExternalTableBuilderBase::GetTableProperties()` with the logical totals tracked by the external-table adapter. Format-specific properties such as `data_size` remain unchanged.
-* The `FSWritableFile` passed to `ExternalTableFactory::NewTableBuilder()` now reports logical file size including RocksDB-buffered data and exposes the underlying file's direct-I/O mode and required buffer alignment.
-* `Iterator::Refresh()` now returns `NotSupported` on iterators from a secondary DB's `DB::NewIterators()` only, because those iterators are pinned to one cross-column-family read view. Iterators from `DB::NewIterator()` are unaffected; to advance a batch, call `DB::NewIterators()` again after `TryCatchUpWithPrimary()`.
-* `SstFileReader` now reports standard SST read statistics and file I/O listener notifications, and honors the configured read rate limiter.
-
-### Bug Fixes
-* Fixed full recovery from retryable background errors to atomically advance WAL replay boundaries for all column families, preventing partial recovery of multi-column-family write batches after a failed recovery flush.
-* Fixed RocksDB builds on big-endian architectures such as s390x by disabling the optional persistent fault-injection log, whose binary format is little-endian-only.
-* Fixed `DB::ClipColumnFamily()` deleting a non-L0 SST file whose largest key equals `begin_key`, which lost keys at the start of the kept range.
-* Fixed swapped `oldest_key_time` and `newest_key_time` values in the `table_file_creation` event log entry.
-* Fixed `ExternalTableReader::VerifyChecksum()` results not being honored by the external table adapter.
-* Fixed a bug in manifest handling that could lead to a hang or memory corruption in the case of LSM sanity checks being fatally violated (exceptional; see `force_consistency_checks`).
-* Fixed `MultiGet()` with `ReadOptions::read_tier == kBlockCacheTier` reading data blocks from disk when `allow_mmap_reads` is false. Keys whose data block is not in the block cache now return `Status::Incomplete()`, the same as `Get()`.
-* Fixed trace replay (`DB::NewDefaultReplayer()`, db_bench `replay`) failing every read record (Get, MultiGet, iterator seek) on the default column family with `Corruption: Invalid Column Family ID` when the default column family handle was not passed, which is always the case in db_bench with `--num_column_families=1`.
-* Fixed multi-threaded `Replayer::Replay()` ignoring errors from executing trace records and returning OK. It now stops and returns the error, including `Status::NotSupported()` from executing a record, as single-threaded replay does.
-* Fixed secondary DB `NewIterators()` returning iterators from different database states or blocking for `TryCatchUpWithPrimary()` by serving the last completed catch-up view.
-
-### Performance Improvements
-* Single Get coroutine reads using non-mmap, non-direct I/O on a `kFSBuffer`-capable `FileSystem` now use `FSRandomAccessFile::SubmitReadAsync()` instead of falling back to synchronous `Read()`. When rate-limited, these reads acquire their full token budget before submission to preserve a single filesystem-owned buffer, which can make physical I/O burstier than reads using caller-provided buffers.

-## 11.11.0 (09/21/2026)
-### New Features
-* External tables now support DB-assigned global sequence numbers when `IngestExternalFileOptions::allow_global_seqno` is enabled, allowing overlapping external tables to be ingested across multiple levels when compactions are disabled. This includes the deprecated `write_global_seqno` path when the reader supplies the properties block's file offset.
-* Added checksum handoff support for SST file writes when `BlockBasedTableOptions::checksum` is `kCRC32c`, allowing block and trailer CRC32C checksums to be passed from the table builder to the file writer for buffered-data validation and filesystem in-flight write protection.
-* Enhanced `sst_dump --command=recompress` to be more powerful for benchmarking, including through automation with a new `--json` option for machine-readable output.
-
-### Public API Changes
-* Changed the experimental async read statistics API by removing `DB::AsyncCallback::EnableStats()` and changing `OnComplete(const PerfContext*, const IOStatsContext*)` to `OnComplete()`. Callers must configure TLS statistics before each async or coroutine read. `DB::GetAsync()` and `DB::MultiGetAsync()` callbacks must copy per-operation statistics from TLS during `OnComplete()`; coroutine users must copy them from inside a `CoroStackableDB` hook before suspending again. Each operation leaves TLS statistics collection disabled.
-* Added `Compressor::MaybeOverrideCompressionOptions()` (EXPERIMENTAL), an omnibus hook letting a custom compressor adjust the subset of `CompressionOptions` that the SST builder applies rather than the compressor itself: `parallel_threads`, `max_compressed_bytes_per_kb`, `auto_skip`, and `auto_skip_min_sample_every` (and potentially more in the future). This deprecates `Compressor::GetRecommendedParallelThreads()`, which it subsumes; the default implementation still honors an overridden `GetRecommendedParallelThreads()` for compatibility.
-* Added experimental `CoroDB::CoGet()` and `CoroDB::CoMultiGet()` overloads for point reads from an `SstFileReader`.
-* Added experimental `DB::GetWithMetadata()` and `DB::MultiGetWithMetadata()` APIs with opt-in output metadata for key timestamps and explicit-snapshot newer-version detection.
-* Added a `DB::NewIterators()` overload that accepts parallel vectors of `ReadOptions` and column family handles, allowing each returned iterator to use independent read settings while sharing a consistent database state. The vectors must have the same size, all snapshots must be null or identical, and all `tailing` settings must match.
-* Added `ReadOptions::custom_context`, an opaque, non-owning pointer passed through table reads so external table implementations can consume application-defined read options.
-
-### Behavior Changes
-* `ExternalTableReader::MultiGet()` is now used by RocksDB's `DB::MultiGet()` path. Previously, the external table adapter used `TableReader`'s fallback, which called `ExternalTableReader::Get()` separately for each key.
-* `DB::OpenAndCompact()` now requires `output_directory` to be a simple name for a new subdirectory when the new `use_session_tmp_dir_for_remote_compaction` DB option is enabled. The option places that subdirectory under the canonical `<dbname>/session_tmp/` root, and `DB::Open()` deletes stale contents under the root after recovery. The disabled default preserves the existing `<dbname>/<output_directory>` layout without automatic cleanup. Previously, remote-compaction output directories were created directly under `<dbname>`, which made it challenging to safely identify and delete obsolete files.
-* Several block-based SST table properties now better support compression benchmarking and optimization: `uncompressed_data_size` is now persisted in the file (previously it was computed only at write time and read back as 0); a new `lsm_info_at_creation` property records the LSM level and "bottommost" status at the file's creation, distinguishing "not applicable" (e.g. SstFileWriter files) from "unknown" (older files); and the `compression_options` property now records the full compression manager configuration instead of only its name.
-
-### Bug Fixes
-* Fixed a usually-minor performance bug where `Cache::ApplyToAllEntries()` used single-entry batches instead of the intended 256-entry default for `ApplyToAllEntriesOptions::average_entries_per_lock`. All of the Cache implementations (LRU and HCC) benefit from the fix, but the disfavored LRU cache was especially impacted by repeated mutex acquisition and release.
-* Fixed stats-disabled coroutine and asynchronous reads inheriting enabled TLS statistics state when interleaved with stats-enabled reads on the same executor. Each read now uses its captured per-call configuration, while enabled request counters remain isolated across suspensions.
-* Fixed a bug where a remote compaction (`CompactionService` / `DB::OpenAndCompact`) requested with `OpenAndCompactOptions::allow_resumption=true` but for which resumption was internally disabled (incompatible with `paranoid_file_checks` or output-iteration verification) could fail a retried attempt, because the output directory was not cleaned before starting fresh and output files left by a previously interrupted attempt collided with the reused file numbers.
-* Fixed a bug where a remote compaction (`CompactionService` / `DB::OpenAndCompact`) could fail when the primary rotated its MANIFEST while the worker was opening the primary's directory read-only. The open reads `CURRENT`, and the primary publishes a new MANIFEST by renaming a freshly written `CURRENT` over the old one; on file systems without POSIX read-after-unlink semantics (remote/object stores) the replaced object is then reported as gone (`PathNotFound`/`NotFound`, or `TryAgain` for the MANIFEST equivalent) instead of remaining readable. `DB::OpenAndCompact()` now retries the secondary open a bounded, configurable number of times for those transient statuses, so a concurrent rotation no longer fails the compaction (which, for a `CompactionService` that does not fall back to a local compaction, became a background error on the primary).
-* Fixed secondary DB `NewIterators()` returning iterators from different database states when `TryCatchUpWithPrimary()` runs concurrently.
-* Fixed a bug where a `SeekToFirst()` on an iterator previously used for a `Seek()` could end the scan early and silently omit keys with `ReadOptions::async_io`, or otherwise run with readahead effectively disabled. Affects scans using `ReadOptions::prefix_same_as_start` together with `ReadOptions::auto_readahead_size` (enabled by default); memory-mapped reads are unaffected.
-
-### Performance Improvements
-* `DB::MultiGetEntityLazy()` now reads all keys of a batch under a single shared per-column-family SuperVersion pin, and a single `LazyWideColumnsBatch::MultiResolve()` coalesces the resulting blob reads across keys: one read per blob file (and one per SST for embedded blobs), for whole-column and byte-range reads alike, instead of reading each key's blobs separately.
-
-
-## 11.10.0 (08/28/2026)
-### New Features
-* Added `BlockBasedTableOptions::optimize_key_common_prefix` as part of new `format_version=8`. When enabled, each data block and index block stores the common user-key prefix of its keys once instead of at every restart point, reducing block size and block-cache footprint for prefix-heavy data and speeding up Seek for bytewise-ordered keys.
-* A new experimental feature spreads out periodic (time-based) compaction trigger times across a fleet of similarly-configured DBs to avoid recurring "thundering herd" triggers, especially with remote compaction. See the new experimental DB option `periodic_compaction_phase_recovery_percent`.
-
-### Public API Changes
-* `IngestExternalFileArg::atomic_replace_range` now supports a range that only partially overlaps existing files, instead of failing. Requires universal compaction and a table factory that supports range deletion; other configurations still fail on partial overlap. The range is also now specified as half-open (`start` inclusive, `limit` exclusive), resolving a previously documented ambiguity in the upper bound.
-* Added an immutable `external_table_config` option that is persisted in OPTIONS files and passed to external table factories during bootstrap.
-
-### Bug Fixes
-* Fixed a liveness bug where RocksDB could remain indefinitely in recovery from a soft background error when concurrent writes continuously generated normal flush requests.
-* Fixed a race in online error recovery where a concurrent higher-severity I/O error could leave a stale retry-flush plan active, prevent the required WAL switch, and create duplicate internal WAL history detected on DB reopen.
-* Fix "bottommost files" infinite compaction loops (`kBottommostFiles`). This happens with the unsupported combination of leveled compaction and `preserve_internal_time_seconds` / `preclude_last_level_data_seconds`, and in an edge case with user-defined timestamps when `full_history_ts_low` is unset. The underlying logic is now more unified to reduce risk of a similar divergence in logic in the future.
-* Fixed `reuse_manifest_on_open` to create a fresh MANIFEST instead of appending after recovery sees an incomplete atomic group at the MANIFEST tail.
-* Starting remote compaction (`CompactionService` / `DB::OpenAndCompact`) is now more efficient and more reliable, by avoiding unnecessary file operations (latency) while using more accurate consistency / precondition checks, both avoiding some spurious failures and rejecting more legitimate inconsistencies. New DBOption `remote_compaction_manifest_floor` can be disabled in case of unexpected problems with the change.
-* Fixed unbounded retention of recovered transaction state by a long-lived secondary opened with `allow_2pc`.
-* Fixed stale reads on secondary instances, where entries replayed from a WAL that the primary had already flushed could shadow the newer values in the flushed files indefinitely. Also fixed a case where a secondary could stop returning such a key altogether while the primary's flushed file holding it was unreadable.
-* Fixed subset checkpoints to discard tolerated MANIFEST tail corruption before appending column-family drop records.
-
-### Performance Improvements
-* Improved compaction CPU efficiency for column families using an `SstPartitioner` (such as the built-in `SstPartitionerFixedPrefix`): when the partitioner can express its next boundary as a key prefix via the new `SstPartitioner::ShouldPartitionByPrefix()` API, compaction now checks that cached prefix inline instead of copying every user key and making a virtual `ShouldPartition()` call for each key-value written to an SST.
-
-## 11.9.0 (08/14/2026)
-### New Features
-* Added an integrated and improved compression auto-skip feature (new CompressionOptions, still experimental) that saves CPU by skipping compression when and where the overall ratio is inadequate. This improves on the previous auto-skip compression manager by (a) taking achieved compression ratios into account, (b) using a continuously evolving payoff estimate, and (c) combining natively with parallel compression.
-* Added the `blob_file_writable_file_max_buffer_size` mutable column family option. When set to a non-zero value, blob-file writers use it as their `WritableFileWriter` max buffer size instead of inheriting `DBOptions::writable_file_max_buffer_size`.
-* Added an experimental lazy wide-column read API, `DB::GetEntityLazy()` / `DB::MultiGetEntityLazy()` (see `include/rocksdb/lazy_wide_columns.h`). The returned `LazyWideColumns` leaves blob-backed columns as unresolved references and, like an iterator, stays valid after the call returns, so the caller resolves only the columns -- and only the byte ranges -- it needs; a byte-range read of an uncompressed blob (separate-file or embedded) reads just those bytes from storage. Adds `Env::IOActivity::kLazyResolve` and `rocksdb.blobdb.lazy.*` statistics. Requires `max_open_files == -1`.
-* Added DB property `rocksdb.num-running-remote-compactions`, reporting the number of compaction service jobs currently waiting in `CompactionService::Wait()`.
-* Added DB property `rocksdb.num-unscheduled-compactions`, reporting compactions waiting in the DB's internal compaction queue but not yet assigned to a background job.
-* Added `DB::AbortCompactions()` and `DB::ResumeCompactions()` for per-column-family compaction abort and resume, with the same active-abort semantics as the DB-wide `AbortAllCompactions()`/`ResumeAllCompactions()` but scoped to a single column family. Calls are reference-counted independently per column family and compose with the DB-wide abort.
-
-### Public API Changes
-* Add IndexFactory compatibility names for the existing user-defined index API.
-* Added the experimental `CoroDB` capability, exposed by `DB::GetCoroDB()`, with lazy native coroutine variants of `Get` and `MultiGet`. The existing `DB::GetAsync()` and `DB::MultiGetAsync()` APIs dispatch through it.
-* Added `rocksdb_batched_multi_get_pinned_cf()` to return batch-owned pinned MultiGet values and per-key errors without allocating one wrapper per found value.
-* Add `DBOptions::read_io_executor_threads` to increase the maximum thread count of the shared filesystem read I/O executor used for asynchronous reads when opening a DB. Opening a DB never reduces the shared executor thread count. Change the experimental `FSRandomAccessFile::SubmitReadAsync()` API to return whether the asynchronous path was used, and add the `FILE_SUBMIT_ASYNC_READ_FALLBACK` ticker to count calls that fall back to synchronous reads.
-* `ReadOptions::table_filter` is now a *pointer* to a caller-owned `std::function` instead of a `std::function` value, to improve efficiency in copying and destroying `ReadOptions` objects (which RocksDB does internally). This is a breaking change for users of this relatively obscure option, who will now need to declare a `std::function` that outlives the read. As a side effect of `ReadOptions` being trivially copyable, new but legitimate compiler warnings may surface.
-* Removed the experimental `CreateAutoSkipCompressionManager()`. Auto-skip compression is now a first-class feature of the block-based table builder, controlled by the new experimental `CompressionOptions::auto_skip`.
-* Added `CoroStackableDB` for implementing wrappers over native coroutine reads and used it to add coroutine `Get` and `MultiGet` support to `DBWithTTL` and WritePrepared `TransactionDB`. A stackable wrapper advertises coroutine support only when its wrapped DB supports it; TTL value decoding and transaction visibility semantics are preserved.
-* Added a `kSstFileWriter` value to `TableFileCreationReason`, which `SstFileWriter` now reports instead of the catch-all `kMisc`. This, along with new `db_name` and `is_remote_compaction` fields in `FilterBuildingContext`, improves the contextual information available to custom filter and compression strategies.
-* Renamed `TransactionLogIterator` to `WalIterator` (and `include/rocksdb/transaction_log.h` to `include/rocksdb/wal_iterator.h`), because it iterates the write-ahead log and is unrelated to `TransactionDB`. The old names still work. `DB::GetUpdatesSince()` is unchanged. In Java, `WalIterator` is the new name and `TransactionLogIterator` remains as a subclass. Also documented existing behavior that was previously unstated: only writes that reached the WAL are visible (so `WriteOptions::disableWAL` and `IngestExternalFile()` leave holes that end iteration), what each iterator state means, and that `GetUpdatesSince()` silently starts later when the requested sequence number is unavailable.
-
-### Bug Fixes
-* Fixed a bug where `BlobFileBuilder` passed an SST path to `OnBlobFileCompleted()` instead of the completed blob path during BlobDB garbage-collection compactions, causing incorrect `SstFileManager` accounting and compaction failures on filesystems where the SST was not yet pathname-visible.
-
-### Performance Improvements
-* When `DBOptions::avoid_unnecessary_blocking_io` is true, obsolete `OPTIONS-*` files found during DB open are deleted by background purge instead of synchronously on the opening thread.
-
-## 11.8.0 (07/28/2026)
-### Public API Changes
-* Add callback-based asynchronous read APIs, `DB::GetAsync()` and `DB::MultiGetAsync()`. The idea is that when IO is required, RocksDB can suspend its internal coroutine read path, allowing the read executor thread to do other work. When the IO is complete, RocksDB invokes the user callback. This requires filesystem support for full performance benefits. A new filesystem API `FSRandomAccessFile::SubmitReadAsync()` is introduced for this. Unlike `ReadAsync`, the filesystem is responsible for eventually calling the callback. `FileSystem::GetReadExecutor()` returns the IO executor whose EventBases run coroutine read processing. In the Posix filesystem, an IO-uring based event loop is used to complete the IO.
-* Added `FlushOptions::listener_wait` (default `false`). When set together with `FlushOptions::wait == true`, `DB::Flush()` will not return until the registered `EventListener::OnFlushCompleted` callbacks for the flushed memtables have finished running. By default (`false`), `Flush(wait=true)` may return as soon as the flush result is committed, which can be before (or while) the `OnFlushCompleted` callbacks execute on the background flush thread. Also added the corresponding C API `rocksdb_flushoptions_set_listener_wait()` / `rocksdb_flushoptions_get_listener_wait()`.
-* Deprecated `PinnableWideColumns::serialized_size()` in favor of the new `PinnableWideColumns::payload_size()`, which returns the total size of the columns' names and values (for a plain value this equals the value size). Relatedly, wide-column read accounting changed subtly: read statistics for entities (`BYTES_READ`, `BYTES_PER_READ`, and the per-key byte counts for `GetEntity`/`MultiGetEntity`) and the `ReadOptions::value_size_soft_limit` threshold now measure entities by this payload size instead of the serialized entity size. This drops serialization framing bytes from those measurements (so reported/limited sizes for entity reads are slightly smaller than before) and makes plain-value and wide-column accounting consistent.
-
-### Behavior Changes
-* `ReadOptions::value_size_soft_limit` now also bounds the blob values resolved from pre-flush blob direct write references during `MultiGet`/`MultiGetEntity` (previously these were resolved after the limit check and read without bound). Enforcement is "always make progress": at least one key is read even if its value alone exceeds the limit, and only once the returned size exceeds the limit do subsequent keys get `Status::Aborted` -- so a caller retrying the aborted keys cannot loop forever on a single value that by itself exceeds the limit.
-
-### Performance Improvements
-* Reduced copying when reading wide-column entities that have blob-referenced columns, whether stored in separate blob files or embedded (same-file) as blob records in the same SST. On the point-lookup (`GetEntity`/`MultiGetEntity`) and blob-backed memtable/direct-write read paths, resolving these columns no longer re-serializes the whole entity into a fresh buffer: inline columns are referenced in place in the pinned entity and each resolved blob value is referenced in place from its fetched buffer. This is enabled by an internal change to `PinnableWideColumns` that lets its columns reference multiple backing buffers.
-
-## 11.7.0 (07/16/2026)
-### Public API Changes
-* Added `RangeLockManagerHandle::SetIsKilledCallback()`, a `std::function<bool()>` predicate polled during range-lock waits. When it returns true, a blocked `GetRangeLock()` wait returns promptly with `Status::Aborted()` instead of waiting for the lock timeout. Range-lock users that install no callback keep the original wait-until-grant-or-timeout behavior.
-* Added `MultiScanArgs::reverse` to support reverse MultiScan reads over bounded scan ranges.
-
-### Behavior Changes
-* When using `LockWAL()`, live-file capture APIs such as checkpoint and backup now flush WAL-disabled unpersisted data; they can block until `UnlockWAL()` or return `Aborted` when called from the same thread that holds `LockWAL()` to avoid deadlock. `UnlockWAL()` must now also be called from the same thread that called `LockWAL()`.
-
-### Performance Improvements
-* Fixed slow DB open with `best_efforts_recovery`, and slow catch-up of secondary and follower (read-only) instances, in which time and memory grew quadratically with the number of files in the DB (so the slowdown was worst for large DBs with long history).
-
-## 11.6.0 (07/02/2026)
-### New Features
-* Added EXPERIMENTAL embedded blob SST support through `SstFileWriter::OpenWithEmbeddedBlobs()`, storing eligible large values as same-file blob records in block-based SST files and resolving them transparently for reads. This niche feature currently supports uncompressed embedded blobs only; compression options are placeholders and compression support is deferred to follow-up work.
-
-### Public API Changes
-* Expanded the C API (`include/rocksdb/c.h`) with a large set of new `rocksdb_*` functions, mostly option getters/setters plus table-properties, job/event-listener, and metadata accessors, a WAL filter, a ReadOptions table filter, and a backup exclude-files callback. Many are now produced by a new semi-automated generator (`tools/c_api_gen/`) from the C++ headers; `include/rocksdb/c.h` remains a single self-contained header and the signatures of pre-existing functions are unchanged.
-
-### Bug Fixes
-* Reverted PR14831 that made range_lock_manager aware of reverse-order CF
-* Fixed a bug in `RandomAccessFileReader::ReadAsync` where an already-aligned direct-IO read request with a null `scratch` and a caller-provided `aligned_buf` would take the "already aligned" fast path and submit the null buffer to the underlying async read (e.g. a null iovec base to io_uring, failing with EFAULT). This could surface as spurious iterator failures during async prefetch (MultiScan with async IO) on direct-IO databases. The async path now allocates a backing buffer in this case, matching the synchronous `Read` path.
-* Fixed a bug where closing a read-only DB instance could delete live SST files created by a concurrent read-write DB sharing the same directory.
-
-## 11.5.0 (06/16/2026)
-### New Features
-* External table readers that open files through `ExternalTableOptions::fs` now update RocksDB SST/file-read statistics and file IO listener callbacks, making external file IO activity visible in existing read metrics.
-* Added `DB::PrepareFileIngestion()`, a two-phase form of `IngestExternalFile`/`IngestExternalFiles`. `PrepareFileIngestion()` performs all of the work that does not require the DB mutex (validating the arguments, reading each external file's metadata, and linking/copying the files into the DB) and returns an opaque `FileIngestionHandle`. `DB::CommitFileIngestionHandle()` (or `DB::CommitFileIngestionHandles()` for several handles at once) then makes the prepared files visible; multiple handles are committed atomically in a single MANIFEST write, or none are. `FileIngestionHandle::Abort()` (or simply destroying the handle) cancels a prepared ingestion and rolls it back. This gives flexibility to the application to Prepare a file separately from when its committed, and may shorten an applications critical path on `IngestExternalFile`.
-* Added two stats histograms reporting the per-call latency (in microseconds) of each successful `IngestExternalFile`/`IngestExternalFiles` call, split by phase: `rocksdb.ingest.external.file.prepare.micros` (argument validation and reading/validating/linking the external files, which does not block live writes) and `rocksdb.ingest.external.file.run.micros` (the ingestion performed under the DB mutex while live writes are blocked). Failed ingestions are not recorded.
-* Added `DBOptions::use_direct_io_for_compaction_reads` (default false). When enabled, compaction-input SST reads use `O_DIRECT` while user reads remain buffered, avoiding page-cache eviction of hot user-read data by sequential compaction scans. Pair with `use_direct_io_for_flush_and_compaction = true` on write-heavy workloads for direct I/O on both compaction inputs and outputs. Rejected at Open when combined with `allow_mmap_reads = true`. No-op when `use_direct_reads = true` is already set (since all reads are already direct).
-
-### Public API Changes
-* `DB::GetPreparedFileInfoForExternalSstIngestion()` can now prepare metadata for a live DB-generated SST file so it can be passed to `IngestExternalFileArg::file_infos`. The input path must exactly match a live table file owned by the source DB, and the returned metadata handle must outlive the ingestion.
-* `ExternalSstFileInfo` gained a `prepared_file_info` member produced by `SstFileWriter::Finish`, and `IngestExternalFileArg` gained a `file_infos` field: a vector of borrowed `const PreparedFileInfo*` pointers, parallel to `external_files`. The owning `ExternalSstFileInfo::prepared_file_info` handle must outlive the ingestion. When set, `IngestExternalFiles()` reuses the supplied per-file metadata instead of re-opening and scanning each file to recompute it, avoiding that extra I/O.
-* Corrected the public C++ option spelling from `memtable_veirfy_per_key_checksum_on_seek` to `memtable_verify_per_key_checksum_on_seek`. RocksDB continues to accept the old misspelled OPTIONS-file key for compatibility, while newly serialized OPTIONS files use the corrected key.
-* Added experimental read-scoped block buffer provider API, configured through `ReadOptions::read_scoped_block_buffer_provider`, for supported block-based table iterator scans and MultiScan reads to use caller-provided read-scoped storage for final data-block contents. When configured, supported provider-backed scan data-block reads bypass the data-block cache. The provider is ignored when mmap reads are enabled. RocksDB may still use ordinary temporary scratch for serialized block bytes, such as when a block may be compressed. Get and MultiGet do not currently provide API guarantees for this provider.
-* Added `FileSystem::SyncFile()` and `Env::SyncFile()` public APIs for syncing or fsyncing a file by name without requiring callers to reopen it as writable.
-
-### Behavior Changes
-* The default `compression` for column families is now `kLZ4Compression` rather than `kSnappyCompression`. This affects only column families that do not explicitly set `compression`, and only newly-written SST files. The change is fully compatible: existing data remains readable with no migration needed, as RocksDB selects the decompressor per block. LZ4 offers slightly better compression ratios and decompression CPU efficiency vs. Snappy and similar compression CPU, tested across various server CPUs. When support is not compiled in, the fallback path for default compression is LZ4 -> Snappy -> NoCompression.
-* Disable parallel compression (ignore `CompressionOptions::parallel_threads`) for fast built-in compressors: Snappy, LZ4 (accelerated, not LZ4HC), and accelerated levels of ZSTD (level < 0). These do not generally benefit from parallel compression. This behavior can be overridden with a custom Compressor from a custom CompressionManager.
-* `PosixFileSystem::OptimizeForCompactionTableRead` now delegates to the base `FileSystem::OptimizeForCompactionTableRead` implementation before applying its Linux-only compaction-readahead clamp (added for #12038). The returned `FileOptions::use_direct_reads` therefore reflects `DBOptions::use_direct_reads`, consistent with the base class and with other `FileSystem` implementations. Previously the override ignored the base implementation and keyed both the returned options and the Linux readahead clamp off the incoming `FileOptions` rather than `DBOptions`. At the in-tree call site the incoming `FileOptions::use_direct_reads` already matches `DBOptions::use_direct_reads`, so this is effectively a no-op for existing configurations; it removes a latent inconsistency where a caller passing `FileOptions` whose `use_direct_reads` disagreed with `DBOptions` would have had the global flag silently ignored for compaction-input reads on Linux. (Note: the `#12038` readahead clamp still keys off the global `use_direct_reads`; it is not skipped for the compaction-only `use_direct_io_for_compaction_reads` path, since that flag enables O_DIRECT after this hook runs.)
-* Brought more unity to `kLZ4Compression` and `kLZ4HCCompression` by giving each access to the other's compression levels. Negative (fast) values previously only available to LZ4 and positive (slow) values previously only available to LZ4HC are now available to both, so configuring a non-default `compression_opts.level` now selects the LZ4 compressor variant. This is a behavior change for previously tolerated but dubious configurations such as positive compression level with `kLZ4Compression`. `kLZ4Compression` and `kLZ4HCCompression` keep their effective default levels, equivalent to -1 and 9 respectively.
-* Removed a discontinuity in `kZSTD` compression levels at `compression_opts.level == 0` by mapping that setting to `level = -1` rather than to `level = 3` as the ZSTD library does internally. This improves the compression auto-tuning landscape.
-
-### Bug Fixes
-* Fixed a bug where the range lock manager would crash with an assertion failure when using a reverse comparator column family.
-
-### Performance Improvements
-* Reduced commit latency when ingesting many external files by allowing `IngestExternalFileOptions::file_opening_threads` to open table readers for committed ingested files using multiple threads.
-* Reduced commit latency for large external file ingestions into the last level by adding `IngestExternalFileOptions::prefetch_lmax_index_and_filter_blocks`, which can skip commit-time index and filter block prefetching for cache-backed table metadata.
-
-## 11.4.0 (06/02/2026)
-### Public API Changes
-* Added `rocksdb_options_set_memtable_batch_lookup_optimization()` and `rocksdb_options_get_memtable_batch_lookup_optimization()` to the C API, exposing the existing `AdvancedColumnFamilyOptions::memtable_batch_lookup_optimization` field. This allows C API users (and downstream language bindings) to enable the skip-list memtable's batch-lookup optimization for `MultiGet`, which caches the search path between consecutive keys and reduces per-key cost from O(log N) to O(log d) where d is the distance between consecutive keys.
-* Added `rocksdb_readoptions_set_optimize_multiget_for_io()` and `rocksdb_readoptions_get_optimize_multiget_for_io()` to the C API, exposing the existing `ReadOptions::optimize_multiget_for_io` field. This allows C API users (and downstream language bindings) to opt out of the multi-level parallel MultiGet path, which only takes effect when the library is built with `USE_COROUTINES`.
-* Added `rocksdb_block_based_table_index_block_search_type_auto` enum constant and the `rocksdb_block_based_options_set_uniform_cv_threshold()` setter to the C API. The constant exposes `BlockSearchType::kAuto`, and the setter exposes `BlockBasedTableOptions::uniform_cv_threshold`. Both are required for `kAuto` index-block search to take effect from the C API: without setting `uniform_cv_threshold >= 0`, the per-block `is_uniform` footer bit is never written, and `kAuto` falls back to binary search at read time.
-* Added `EventListener::OnDBShutdownBegin`, a callback that fires once when a DB begins shutdown, including when RocksDB cleans up a failed `DB::Open()` attempt.
-* Added a new PerfContext counter `blob_cache_read_byte` for blob cache bytes read.
-
-### Behavior Changes
-* Remote compaction now falls back to local compaction when the primary cannot deserialize a successful `CompactionServiceResult` before installing any remote output files.
-* StringToMap (rocksdb/convenience.h) now preserves the outer braces of nested values so each map entry is in self-contained form and can be embedded directly into another `key=value;` string (e.g. SetOptions) without losing inner ';' delimiters. A new symmetric MapToString utility is provided.
-
-### Bug Fixes
-* Fixed a bug where `AbortAllCompactions()` could leave automatic compaction work unscheduled when aborting before the background worker picked it, causing compaction and write stalls until DB restart.
-* Fix a bug where db had a false positive compaction corruption error due to remote compaction service result with `has_accurate_num_input_records=false` not being serialized.
-* Fixed WritePrepared TransactionDB cleanup after retryable commit or rollback write failures so prepared transactions remain rollbackable instead of leaving unresolved prepared state.
-* Fix a rare corruption bug for tiered compaction that incorrectly moved last level range tombstones into proximal level. This corruption error is surfaced when force_consistency_checks is enabled.
-
-### Performance Improvements
-* Reduce the likelihood of user-facing metadata operations blocking on MANIFEST rotation when file creation is slow, such as on remote storage. MANIFEST write batches containing foreground edits from `CreateColumnFamily()`, `DropColumnFamily()`, `CreateColumnFamilyWithImport()`, `IngestExternalFile()`, and `DeleteFilesInRanges()` now get a relaxed file size threshold for triggering MANIFEST rotation; background-only MANIFEST write batches, such as compaction and flush, continue to use the normal threshold. This change should make auto-tuning manifest file size more attractive (see `max_manifest_file_size` and `max_manifest_space_amp_pct` options).
-
-
-## 11.3.0 (05/15/2026)
-### New Features
-* Add experimental DB option `async_wal_precreate` to precreate the next WAL file in a background thread and reduce foreground WAL rotation latency. The option is sanitized to false when WAL recycling is enabled.
-* Added a new `EventListener::OnCompactionPreCommit` callback that fires after a compaction job finishes but before its input files are released (i.e. while `FileMetaData::being_compacted` is still true). Listeners that maintain bookkeeping of which files are currently being compacted can clean up such state in this new callback to avoid races with concurrent compaction picking, where another thread might pick up the same files for a new compaction immediately after `being_compacted` is flipped back to false but before `OnCompactionCompleted` fires. The default implementation is a no-op so this is not a breaking change.
-* Add mutable DBOption `optimize_manifest_for_recovery` (default false). When enabled, RocksDB can reduce recovery work after a clean shutdown, which may lower DB::Open latency on warm reopens.
-* Added public utility APIs `ParseCompressionNameForDisplay()` to convert `TableProperties::compression_name` into a human-readable compression name for both legacy and format_version 7+ SST metadata, including custom `CompressionManager`-provided display names for custom compression types.
-* Add `reuse_manifest_on_open` DBOption (default false). When enabled, DB::Open reuses the existing MANIFEST file for append instead of creating a fresh one, avoiding the cost of serializing the entire database state into a new MANIFEST on the first post-open write. To prevent this feature from interfering with manifest file size auto-tuning, an extra forward-compatible field is now always added to the MANIFEST (to track the last "compacted" size).
-
-### Behavior Changes
-* Read-only open with `error_if_wal_file_exists=true` now tolerates empty WAL files so empty precreated WALs do not prevent inspection.
-* WriteCommitted TransactionDB now matches WritePrepared and WriteUnprepared compaction filtering in both single- and two-write-queue modes: a compaction filter's FilterMergeOperand will not be invoked on merge operands at or below the latest published sequence number.
-
-### Bug Fixes
-* Fixed blob-backed wide-column merge reads to preserve correct status
-propagation and resolution across memtable, read-only, and secondary DB
-paths.
-* Fixed a bug where `DB::GetCreationTimeOfOldestFile()` could return inaccurate results instead of the real creation time when called shortly after opening a legacy DB (one whose manifest lacks `file_creation_time`) with `open_files_async = true`. The API now waits for background SST file loading to complete only when needed; modern DBs are unaffected.
-* Fixed merge reads against wide-column/blob-backed base values to preserve precise failure statuses, including `GetMergeOperands()` and direct-write memtable reads.
-* Fix bug in range tombstone synthesis that covers live keys added during an IngestExternalFile
-* Reject the empty string as a column family name in `DB::CreateColumnFamily` / `DB::CreateColumnFamilies`. Previously such calls returned OK and a usable handle, but the column family was not persisted in the manifest, so any data written to it was silently lost on DB reopen.
-* Fixed a bug where a WriteCommitted TransactionDB using commit-bypass WBWI ingestion could drop an entry that is still visible at the published sequence boundary.
-
-## 11.2.0 (04/18/2026)
-### New Features
-* Added experimental `DBOptions::fast_sst_open` option. When enabled, RocksDB retrieves opaque file system metadata for SST files after flush, compaction, and external file ingestion, persists it in the MANIFEST, and passes it back to the file system on subsequent file opens to accelerate DB open time.
-* Added new option `min_tombstones_for_range_conversion` in `AdvancedColumnFamilyOptions`. When set to a non-zero value N, forward or reverse iteration will convert N or more contiguous point tombstones into a range tombstone in the mutable memtable. Future read operations will then be able to benefit from range tombstone optimizations. There are some limitations when it comes to table_filters, prefix_filters, and UDTs. See header comments for more details.
-* Added read-triggered compaction: a new column family option `read_triggered_compaction_threshold` (default 0, disabled) that marks SST files for compaction when their read frequency (`num_collapsible_entry_reads_sampled / file_size`) exceeds the threshold. This helps reduce read amplification for frequently-read ("hot") keys. A new DB option `max_compaction_trigger_wakeup_seconds` (default 43200s / 12 hours) controls the maximum interval for periodic compaction score re-evaluation, which is necessary for this feature to work on quiet (no-write) databases.
-
-### Public API Changes
-* Added new `WideColumnBlobResolver` interface and `CompactionFilter::FilterV4()` method, including `ResolveColumn()` / `ResolveColumns()` helpers for lazy loading blob column values in wide-column entities during compaction. This allows compaction filters to resolve blob values on-demand, avoiding unnecessary I/O for blob columns they don't need to access.
-* Changed experimental feature `ExternalTableReader::Get` and `ExternalTableReader::MultiGet` to use `PinnableSlice` instead of `std::string` for output values, enabling zero-copy pinning. This will break existing implementations.
-* Added `SstFileReader::Get` and `SstFileReader::MultiGet` overloads that accept `PinnableSlice`/`std::vector<PinnableSlice>*`, enabling zero-copy reads when the underlying `TableReader` supports pinning.
-
-### Behavior Changes
-* Prefix filter changes - when seeking to a key that is out of domain, and total_order_seek is false, total_order_seek is treated as if it were true. When prefix_same_as_start = true, now iterating past a key that is out of domain invalidates the iterator. The existing behavior does not check for InDomain in the DBIter, so Transform() can produce undefined behavior (e.g. key of size 3 on FixedPrefixTransform(4)).
-* Wide-column entities with blob-backed columns now use a new V2 on-disk encoding; older RocksDB versions that do not support wide-column blob separation will reject DBs or SSTs containing those entities.
-
-### Bug Fixes
-* Fix blob garbage accounting for blob direct-write flushes so flush-time filtering and overwrite elision correctly register obsolete blob bytes in blob metadata.
-* Fix a memory accounting leak in IODispatcher where ReadIndex() moved block values out of ReadSet without releasing the associated prefetch memory, causing subsequent prefetches to be blocked when max_prefetch_memory_bytes was set.
-* Fix MultiScan to fall back to synchronous coalesced reads when async I/O is unsupported at runtime.
-
-
-## 11.1.0 (03/23/2026)
-### New Features
-* Add a new option `open_files_async`. The existing behavior is on DB open, we open all sst files and do basic validations. For very large DBs on remote filesystems with many ssts, this may take very long. This option performs these validations instead in the background. Open errors found by this async background task are surfaced as a new background error kAsyncFileOpen.
-* Added `BlockBasedTableOptions::kAuto` index block search type that automatically selects between binary and interpolation search on a per-index-block basis. During SST construction, each index block's key distribution uniformity is analyzed using the coefficient of variation of key gaps, and index blocks with uniform keys use interpolation search while others fall back to binary search. The uniformity threshold is configurable via `BlockBasedTableOptions::uniform_cv_threshold` (default: 0.2).
-* Introduced enforce_write_buffer_manager_during_recovery option to allow WriteBufferManager to be enforced during WAL recovery. (Default: true)
-* Add `memtable_batch_lookup_optimization` option to use batch lookup optimization for memtable MultiGet. For skip list memtables, after each key lookup, the search path is cached and reused for the next key, reducing per-key cost from O(log N) to O(log d) where d is the distance between consecutive keys. Benchmarks show ~7% improvement in memtable-resident MultiGet throughput.
-* Added `BlockBasedTableOptions::PrepopulateBlockCache::kFlushAndCompaction` to prepopulate the block cache during both flush and compaction. Compaction-warmed blocks are inserted at `BOTTOM` priority (vs `LOW` for flush) so they are evicted first under cache pressure. Recommended only for use cases where most or all of the database is expected to reside in cache (e.g., tiered or remote storage where the working set fits in cache).
-* Added new mutable DB option `verify_manifest_content_on_close` (default: false). When enabled, on DB close the MANIFEST file is read back and all records are validated (CRC checksums and logical content). If corruption is detected, a fresh MANIFEST is written from in-memory state.
-
-### Behavior Changes
-* num_reads_sampled now factors in re-seeks and next/prev() on file iterators for files in L1+. next/prev() is discounted by 64x compared to seek due to being a much cheaper call.
-* Remote compaction workers now skip WAL recovery when opening the secondary DB instance, since only the LSM state from MANIFEST is needed for compaction. This reduces I/O and speeds up remote compaction startup.
-
-### Bug Fixes
-* Fix a bug in round-robin compaction that missed selecting input files that are needed to guarantee data correctness and cause crashing in debug builds or silent data corruption in release builds for Get().
-
-## 11.0.0 (02/23/2026)
-### New Features
-* Added support for storing wide-column entity column values in blob files. When `min_blob_size` is configured, large column values in wide-column entities will be stored in blob files, reducing SST file size and improving read performance.
-* Added `CompactionOptionsFIFO::max_data_files_size` to support FIFO compaction trimming based on combined SST and blob file sizes. Added `CompactionOptionsFIFO::use_kv_ratio_compaction` to enable a capacity-derived intra-L0 compaction strategy optimized for BlobDB workloads, producing uniform-sized compacted files for predictable FIFO trimming.
-* Include interpolation search as an alternative to binary search, which typically performs better when keys are uniformly distributed. This is exposed as a new table option `index_block_search_type`. The default is `binary_search`.
-
-### Public API Changes
-* Added new virtual methods `AbortAllCompactions()` and `ResumeAllCompactions()` to the `DB` class. Added new `Status::SubCode::kCompactionAborted` to indicate a compaction was aborted. Added `Status::IsCompactionAborted()` helper method to check if a status represents an aborted compaction.
-* Drop support for reading (and writing) SST files using `BlockBasedTableOptions.format_version` < 2, which hasn't been the default format for about 10 years. An upgrade path is still possible with full compaction using a RocksDB version >= 4.6.0 and < 11.0.0 and then using the newer version.
-* Remove deprecated raw `DB*` variants of `DB::Open` and related functions. Some other minor public APIs were updated as a result
-* Remove deprecated `DB::MaxMemCompactionLevel()`
-* Remove useless option `CompressedSecondaryCacheOptions::compress_format_version`
-* Remove deprecated DB option `skip_checking_sst_file_sizes_on_db_open`. The option was deprecated in 10.5.0 and has been a no-op since then. File size validation is now always performed in parallel during DB open.
-* Remove deprecated `SliceTransform::InRange()` virtual method and the `in_range` callback parameter from `rocksdb_slicetransform_create()` in the C API. `InRange()` was never called by RocksDB and existed only for backward compatibility.
-* Remove deprecated, unused APIs and options: `ReadOptions::managed` and `ColumnFamilyOptions::snap_refresh_nanos`. Corresponding C and Java APIs are also removed.
-* Remove deprecated `SstFileWriter::Add()` method (use `Put()` instead) and the deprecated `skip_filters` parameter from `SstFileWriter` constructors (use `BlockBasedTableOptions::filter_policy` set to `nullptr` to skip filter generation instead).
-
-### Behavior Changes
-* Change the default value of `CompactionOptionsUniversal::reduce_file_locking` from `false` to `true` to improve write stall and reduce read regression
-
-### Bug Fixes
-* Fix longstanding failures that can arise from reading and/or compacting old DB dirs with range deletions (likely from version < 5.19.0) in many newer versions.
-* Fix a bug where WritePrepared/WriteUnprepared TransactionDB with two_write_queues=true could experience "sequence number going backwards" corruption during recovery from a background error, due to allocated-but-not-published sequence numbers not being synced before creating new WAL files.
-
-### Performance Improvements
-* Add a new table option `separate_key_value_in_data_block`. When set to true keys and values will be stored separately in the data block, which can result in higher cpu cache hit rate and better compression. Works best with data blocks with sufficient restart intervals and large values. Previous versions of RocksDB will reject files written using this option.
-
-## 10.11.0 (01/23/2026)
-### Public API Changes
-* New SetOptions API that allows setting options for multiple CFs, avoiding the need to reserialize OPTIONS file for each CF
-* Remove remaining pieces of Lua integration
-
-### Behavior Changes
-* The new default for `BlockBasedTableOptions::format_version` is 7, which has been supported since RocksDB 10.4.0 and is required in order to use CompressionManagers supporting custom compression types.
-
-### Bug Fixes
-* Fixed a small performance bug with `format_version=7` when decompressing formats other than Snappy and ZSTD.
-* Fixed an infinite compaction loop bug with User-Defined Timestamps (UDT) where bottommost files were repeatedly marked for compaction even though their timestamp could not be collapsed.
-* Bugfix for persisted UDT record sequence number zeroing logic.
-
-## 10.10.0 (12/16/2025)
-### Bug Fixes
-* Fixed a bug in best-efforts recovery that causes use-after-free crashes when accessing SST files that were cached during the recovery.
-* Fix resumable compaction incorrectly allowing resumption from a truncated range deletion that is not well handled currently.
-* Fixed a bug in `PosixRandomFileAccess` IO uring submission queue ownership & management. Fix eliminates the false positive 'Bad cqe data' IO errors in `PosixRandomFileAccess::MultiRead` when interleaved with `PosixRandomFileAccess::ReadAsync` on the same thread.
-
-## 10.9.0 (11/21/2025)
-### New Features
-* Added an auto-tuning feature for DB manifest file size that also (by default) improves the safety of existing configurations in case `max_manifest_file_size` is repeatedly exceeded. The new recommendation is to set `max_manifest_file_size` to something small like 1MB and tune `max_manifest_space_amp_pct` as needed to balance write amp and space amp in the manifest. Refer to comments on those options in `DBOptions` for details. Both options are (now) mutable.
-* Added a new API to support option migration for multiple column families
-* Added new option target_file_size_is_upper_bound  that makes most compaction output SST files come close to the target file size without exceeding it, rather than commonly exceeding it by some fraction (current behavior). For now the new behavior is off by default, but we expect to enable it by default in the future.
-* Add a new option allow_trivial_move in CompactionOptions to allow CompactFiles to perform trivial move if possible. By default the flag of allow_trivial_move is false, so it preserve the original behavior.
-
-### Public API Changes
-* To reduce risk of ODR violations or similar, `ROCKSDB_USING_THREAD_STATUS` has been removed from public headers and replaced with static `const bool ThreadStatus::kEnabled`. Some other uses of conditional compilation have been removed from public API headers to reduce risk of ODR violations or other issues.
-
-### Behavior Changes
-* PosixWritableFile now repositions the seek pointer to the new end of file after a call to Truncate.
-* Updated standalone range deletion L0 file compaction behavior to avoid compacting with any newer L0 files (which is expensive and not useful).
-
-### Bug Fixes
-* Fix a bug where compaction with range deletion can persist kTypeMaxValid in MANIFEST as file metadata. kTypeMaxValid is not supposed to be persisted and can change as new value types are introduced. This can cause a forward compatibility issue where older versions of RocksDB don't recognize kTypeMaxValid from newer versions. A new placeholder value type kTypeTruncatedRangeDeletionSentinel is also introduced to replace kTypeMaxValid when reading existing SST files' metadata from MANIFEST. This allows us to strengthen some checks to avoid using kTypeMaxValid in the future.
-* Fixed a bug where `DB::GetSortedWalFiles()` could hang when waiting for a purge operation that found nothing to do (potentially triggered by iterator release, flush, compaction, etc.).
-* Fixed a bug in MultiScan where `max_sequential_skip_in_iterations` could cause the iterator to seek backward to already-unpinned blocks when the same user key spans multiple data blocks, leading to assertion failures or seg fault.
-* Fixed a bug for `WAL_ttl_seconds > 0` use cases where the newest archived WAL files could be incorrectly deleted when the system clock moved backwards.
-
-### Performance Improvements
-* Added optimization that allowed for the asynchronous prefetching of all data outlined in a multiscan iterator. This optimization was applied to the level iterator, which prefetches all data through each of the block-based iterators.
-
-## 10.8.0 (10/21/2025)
-### New Features
-* Add kFSPrefetch to FSSupportedOps enum to allow file systems to indicate prefetch support capability, avoiding unnecessary prefetch system calls on file systems that don't support them.
-* Added experimental support `OpenAndCompactOptions::allow_resumption` for resumable compaction that persists progress during `OpenAndCompact()`, allowing interrupted compactions to resume from the last progress persitence. The default behavior is to not persist progress.
-
-### Public API Changes
-* Allow specifying output temperature in CompactionOptions
-* Added `DB::FlushWAL(const FlushWALOptions&)` as an alternative to `DB::FlushWAL(bool sync)`, where `FlushWALOptions` includes a new `rate_limiter_priority` field (default `Env::IO_TOTAL`) that allows rate limiting and priority passing of manual WAL flush's IO operations.
-* The MultiScan API contract is updated. After a multi scan range got prepared with Prepare API call, the following seeks must seek the start of each prepared scan range in order. In addition, when limit is set, upper bound must be set to the same value of limit before each seek
-
-### Behavior Changes
-* `kChangeTemperature` FIFO compaction will now honor `compaction_target_temp` to all levels regardless of `cf_options::last_level_temperature`
-* Allow UDIs with a non BytewiseComparator
-
-### Bug Fixes
-* Fix incorrect MultiScan seek error status due to bugs in handling range limit falling between adjacent SST files key range.
-* Fix a bug in Page unpinning in MultiScan
-
-### Performance Improvements
-* Fixed a performance regression in LZ4 compression that started in version 10.6.0
-
-## 10.7.0 (09/19/2025)
-### New Features
-* Add the fail_if_no_udi_on_open flag in BlockBasedTableOption to control whether a missing user defined index block in a SST is a hard error or not.
-* A new flag memtable_verify_per_key_checksum_on_seek is added to AdvancedColumnFamilyOptions. When it is enabled, it will validate key checksum along the binary search path on skiplist based memtable during seek operation.
-* Introduce option MultiScanArgs::use_async_io to enable asynchronous I/O during MultiScan, instead of waiting for I/O to be done in Prepare().
-* Add new option `MultiScanArgs::max_prefetch_size` that limits the memory usage of per file pinning of prefetched blocks.
-* Improved `sst_dump` by allowing standalone file and directory arguments without `--file=`. Also added new options and better output for `sst_dump --command=recompress`. See `sst_dump --help`
-
-### Public API Changes
-* HyperClockCache with no `estimated_entry_charge` is now production-ready and is the preferred block cache implementation vs. LRUCache. Please consider updating your code to minimize the risk of hitting performance bottlenecks or anomalies from LRUCache. See cache.h for more detail.
-* RocksDB now requires a C++20 compatible compiler (GCC >= 11, Clang >= 10, Visual Studio >= 2019), including for any code using RocksDB headers.
-* MultiScanArgs used to have a default constructor with default parameter of BytewiseComparator. Now it always requires Comparator in its constructor.
-
-### Behavior Changes
-* The default provided block cache implementation is now HyperClockCache instead of LRUCache, when `block_cache` is nullptr (default) and `no_block_cache==false` (default). We recommend explicitly creating a HyperClockCache block cache based on memory budget and sharing it across all column families and even DB instances. This change could expose previously hidden memory or resource leaks.
-
-### Bug Fixes
-* Reported numbers for compaction and flush CPU usage now include time spent by parallel compression worker threads. This now means compaction/flush CPU usage could exceed the wall clock time.
-* Fix a race condition in FIFO size-based compaction where concurrent threads could select the same non-L0 file, causing assertion failures in debug builds or "Cannot delete table file from LSM tree" errors in release builds.
-* Fix a bug in RocksDB MultiScan with UDI when one of the scan ranges is determined to be empty by the UDI, which causes incorrect results.
-
-### Performance Improvements
-* Add a new table property "rocksdb.key.smallest.seqno" which records the smallest sequence number of all keys in file. It makes ingesting DB generated files faster by
-avoiding scanning the whole file to find the smallest sequence number.
-* Add a new experimental PerKeyPointLockManager to improve efficiency under high lock contention. PointLockManager was not efficient when there is high write contention on same key, as it uses a single conditional variable per lock stripe. PerKeyPointLockManager uses per thread conditional variable supporting fifo order. Although this is an experimental feature. By default, it is disabled. A new boolean flag TransactionDBOptions::use_per_key_point_lock_mgr is added to optionally enable it. Search the flag in code for more info.
-Together, a new configuration TransactionOptions::deadlock_timeout_us is added, which allows the transaction to wait for a short period before perform deadlock detection. When the workload has low lock contention, the deadlock_timeout_us can be configured to be slightly higher than average transaction execution time, so that transaction would likely be able to take the lock before deadlock detection is performed when it is waiting for a lock. This allows transaction to reduce CPU cost on performing deadlock detection, which could be expensive in CPU time. When the workload has high lock contention, the deadlock_timeout_us can be configured to 0, so that transaction would perform deadlock detection immediately. By default the value is 0 to keep the behavior same as before.
-* Majorly improved CPU efficiency and scalability of parallel compression (`CompressionOptions::parallel_threads` > 1), though this efficiency improvement makes parallel compression currently incompatible with UserDefinedIndex and with old setting of `decouple_partitioned_filters=false`. Parallel compression is now considered a production-ready feature. Maximum performance is available with `-DROCKSDB_USE_STD_SEMAPHORES` at compile time, but this is not currently recommended because of reported bugs in implementations of `std::counting_semaphore`/`binary_semaphore`.
-
-## 10.6.0 (08/22/2025)
-### New Features
-* Introduce column family option `cf_allow_ingest_behind`. This option aims to replace `DBOptions::allow_ingest_behind` to enable ingest behind at the per-CF level. `DBOptions::allow_ingest_behind` is deprecated.
-* Introduce `MultiScanArgs::io_coalesce_threshold` to allow a configurable IO coalescing threshold.
-
-### Public API Changes
-* `IngestExternalFileOptions::allow_db_generated_files` now allows files ingestion of any DB generated SST file, instead of only the ones with all keys having sequence number 0.
-* `decouple_partitioned_filters = true` is now the default in BlockBasedTableOptions.
-* GetTtl() API is now available in TTL DB
-* Minimum supported version of LZ4 library is now 1.7.0 (r129 from 2015)
-* Some changes to experimental Compressor and CompressionManager APIs
-* A new Filesystem::SyncFile function is added for syncing a file that was already written, such as on file ingestion. The default implementation matches previous RocksDB behavior: re-open the file for read-write, sync it, and close it. We recommend overriding for FileSystems that do not require syncing for crash recovery or do not handle (well) re-opening for writes.
-
-### Behavior Changes
-* When `allow_ingest_behind` is enabled, compaction will no longer drop tombstones based on the absence of underlying data. Tombstones will be preserved to apply to ingested files.
-
-### Bug Fixes
-* Files in dropped column family won't be returned to the caller upon successful, offline MANIFEST iteration in `GetFileChecksumsFromCurrentManifest`.
-* Fix a bug in MultiScan that causes it to fall back to a normal scan when dictionary compression is enabled.
-* Fix a crash in iterator Prepare() when fill_cache=false
-* Fix a bug in MultiScan where incorrect results can be returned when a Scan's range is across multiple files.
-* Fixed a bug in remote compaction that may mistakenly delete live SST file(s) during the cleanup phase when no keys survive the compaction (all expired)
-* Allow a user defined index to be configured from a string.
-* Make the User Defined Index interface consistently use the user key format, fixing the previous mixed usage of internal and user key.
-
-### Performance Improvements
-* Small improvement to CPU efficiency of compression using built-in algorithms, and a dramatic efficiency improvement for LZ4HC, based on reusing data structures between invocations.
-
-## 10.5.0 (07/18/2025)
-### Public API Changes
-* DB option skip_checking_sst_file_sizes_on_db_open is deprecated, in favor of validating file size in parallel in a thread pool, when db is opened. When DB is opened, with paranoid check enabled, a file with the wrong size would fail the DB open. With paranoid check disabled, the DB open would succeed, the column family with the corrupted file would not be read or write, while the other healthy column families could be read and write normally. When max_open_files option is not set to -1, only a subset of the files will be opened and checked. The rest of the files will be opened and checked when they are accessed.
-
-### Behavior Changes
-* PessimisticTransaction::GetWaitingTxns now returns waiting transaction information even if the current transaction has timed out. This allows the information to be surfaced to users for debugging purposes once it is known that the timeout has occurred.
-* A new API GetFileSize is added to FSRandomAccessFile interface class. It uses fstat vs stat on the posix implementation which is more efficient. Caller could use it to get file size faster. This function might be required in the future for FileSystem implementation outside of the RocksDB code base.
-* RocksDB now triggers eligible compactions every 12 hours when periodic compaction is configured. This solves a limitation of the compaction trigger mechanism, which would only trigger compaction after specific events like flush, compaction, or SetOptions.
-
-### Bug Fixes
-* Fix a bug in BackupEngine that can crash backup due to a null FSWritableFile passed to WritableFileWriter.
-* Fix DB::NewMultiScan iterator to respect the scan upper bound specified in ScanOptions
-
-### Performance Improvements
-* Optimized MultiScan using BlockBasedTable to coalesce I/Os and prefetch all data blocks.
-
-## 10.4.0 (06/20/2025)
-### New Features
-* Add a new CF option `memtable_avg_op_scan_flush_trigger` that supports triggering memtable flush when an iterator scans through an expensive range of keys, with the average number of skipped keys from the active memtable exceeding the threshold.
-* Vector based memtable now supports concurrent writers (DBOptions::allow_concurrent_memtable_write) #13675.
-* Add new experimental `TransactionOptions::large_txn_commit_optimize_byte_threshold` to enable optimizations for large transaction commit by transaction batch data size.
-* Add a new option `CompactionOptionsUniversal::reduce_file_locking` and if it's true, auto universal compaction picking will adjust to minimize locking of input files when bottom priority compactions are waiting to run. This can increase the likelihood of existing L0s being selected for compaction, thereby improving write stall and reducing read regression.
-* Add new `format_version=7` to aid experimental support of custom compression algorithms with CompressionManager and block-based table. This format version includes changing the format of `TableProperties::compression_name`.
-
-### Public API Changes
-* Change NewExternalTableFactory to return a unique_ptr instead of shared_ptr.
-* Add an optional min file size requirement for deletion triggered compaction. It can be specified when creating `CompactOnDeletionCollectorFactory`.
-
-### Behavior Changes
-* `TransactionOptions::large_txn_commit_optimize_threshold` now has default value 0 for disabled. `TransactionDBOptions::txn_commit_bypass_memtable_threshold` now has no effect on transactions.
-
-### Bug Fixes
-* Fix a bug where CreateColumnFamilyWithImport() could miss the SST file for the memtable flush it triggered. The exported CF then may not contain the updates in the memtable when CreateColumnFamilyWithImport() is called.
-* Fix iterator operations returning NotImplemented status if disallow_memtable_writes and paranoid_memory_checks CF options are both set.
-* Fixed handling of file checksums in IngestExternalFile() to allow providing checksums using recognized but not necessarily the DB's preferred checksum function, to ease migration between checksum functions.
-
-## 10.3.0 (05/17/2025)
-### New Features
-* Add new experimental `CompactionOptionsFIFO::allow_trivial_copy_when_change_temperature` along with `CompactionOptionsFIFO::trivial_copy_buffer_size` to allow optimizing FIFO compactions with tiering when kChangeTemperature to move files from source tier FileSystem to another tier FileSystem via trivial and direct copying raw sst file instead of reading thru the content of the SST file then rebuilding the table files.
-* Add a new field to Compaction Stats in LOG files for the pre-compression size written to each level.
-* Add new experimental `TransactionOptions::large_txn_commit_optimize_threshold` to enable optimizations for large transaction commit with per transaction threshold. `TransactionDBOptions::txn_commit_bypass_memtable_threshold` is deprecated in favor of this transaction option.
-* [internal team use only] Allow an application-defined `request_id` to be passed to RocksDB and propagated to the filesystem via IODebugContext
-
-### Bug Fixes
-* Fix a bug where transaction lock upgrade can incorrectly fail with a Deadlock status. This happens when a transaction has a non-zero timeout and tries to upgrade a shared lock that is also held by another transaction.
-* Pass wrapped WritableFileWriter pointer to ExternalTableBuilder so that the file checksum can be correctly calculated and returned by SstFileWriter for external table files.
-* Fix an infinite-loop bug in transaction locking. This can happen if a transaction reaches lock limit and its time out expires before it attempts to wait for it.
-* Fixed a potential data race with `CompressionOptions::parallel_threads > 1` and a `TablePropertiesCollector` overriding `BlockAdd()`.
-
-## 10.2.0 (04/21/2025)
-### New Features
-* Provide histogram stats `COMPACTION_PREFETCH_BYTES` to measure number of bytes for RocksDB's prefetching (as opposed to file
-system's prefetch) on SST file during compaction read
-* A new API DB::GetNewestUserDefinedTimestamp is added to return the newest user defined timestamp seen in a column family
-* Introduce API `IngestWriteBatchWithIndex()` for ingesting updates into DB while bypassing memtable writes. This improves performance when writing a large write batch to the DB.
-* Add a new CF option `memtable_op_scan_flush_trigger` that triggers a flush of the memtable if an iterator's Seek()/Next() scans over a certain number of invisible entries from the memtable.
-
-### Public API Changes
-* AdvancedColumnFamilyOptions.max_write_buffer_number_to_maintain is deleted. It's deprecated since introduction of a better option max_write_buffer_size_to_maintain since RocksDB 6.5.0.
-* Deprecated API `DB::MaxMemCompactionLevel()`.
-* Deprecated `ReadOptions::ignore_range_deletions`.
-* Deprecated API `experimental::PromoteL0()`.
-* Added arbitrary string map for additional options to be overridden for remote compactions

-
-## 10.1.0 (03/24/2025)
-### New Features
-* Added a new `DBOptions.calculate_sst_write_lifetime_hint_set` setting that allows to customize which compaction styles SST write lifetime hint calculation is allowed on. Today RocksDB supports only two modes `kCompactionStyleLevel` and `kCompactionStyleUniversal`.
-* Add a new field `num_l0_files` in `CompactionJobInfo` about the number of L0 files in the CF right before and after the compaction
-* Added per-key-placement feature in Remote Compaction
-* Implemented API DB::GetPropertiesOfTablesByLevel that retrieves table properties for files in each LSM tree level
-
-### Public API Changes
-* `GetAllKeyVersions()` now interprets empty slices literally, as valid keys, and uses new `OptSlice` type default value for extreme upper and lower range limits.
-* `DeleteFilesInRanges()` now takes `RangeOpt` which is based on `OptSlice`. The overload taking `RangePtr` is deprecated.
-* Add an unordered map of name/value pairs, ReadOptions::property_bag, to pass opaque options through to an external table when creating an Iterator.
-* Introduced CompactionServiceJobStatus::kAborted to allow handling aborted scenario in Schedule(), Wait() or OnInstallation() APIs in Remote Compactions.
-* format\_version < 2 in BlockBasedTableOptions is no longer supported for writing new files. Support for reading such files is deprecated and might be removed in the future. `CompressedSecondaryCacheOptions::compress_format_version == 1` is also deprecated.

-### Behavior Changes
-* `ldb` now returns an error if the specified `--compression_type` is not supported in the build.
-* MultiGet with snapshot and ReadOptions::read_tier = kPersistedTier will now read a consistent view across CFs (instead of potentially reading some CF before and some CF after a flush).

-
-### Bug Fixes

-
-## 10.0.0 (02/21/2025)
-### New Features
-* Introduced new `auto_refresh_iterator_with_snapshot` opt-in knob that (when enabled) will periodically release obsolete memory and storage resources for as long as the iterator is making progress and its supplied `read_options.snapshot` was initialized with non-nullptr value.
-* Added the ability to plug-in a custom table reader implementation. See include/rocksdb/external_table_reader.h for more details.
-* Experimental feature: RocksDB now supports FAISS inverted file based indices via the secondary indexing framework. Applications can use FAISS secondary indices to automatically quantize embeddings and perform K-nearest-neighbors similarity searches. See `FaissIVFIndex` and `SecondaryIndex` for more details. Note: the FAISS integration currently requires using the BUCK build.
-* Add new DB property `num_running_compaction_sorted_runs` that tracks the number of sorted runs being processed by currently running compactions
-* Experimental feature: added support for simple secondary indices that index the specified column as-is. See `SimpleSecondaryIndex` and `SecondaryIndex` for more details.
-* Added new `TransactionDBOptions::txn_commit_bypass_memtable_threshold`, which enables optimized transaction commit (see `TransactionOptions::commit_bypass_memtable`) when the transaction size exceeds a configured threshold.
-
-### Public API Changes
-* Updated the query API of the experimental secondary indexing feature by removing the earlier `SecondaryIndex::NewIterator` virtual and adding a `SecondaryIndexIterator` class that can be utilized by applications to find the primary keys for a given search target.
-* Added back the ability to leverage the primary key when building secondary index entries. This involved changes to the signatures of `SecondaryIndex::GetSecondary{KeyPrefix,Value}` as well as the addition of a new method `SecondaryIndex::FinalizeSecondaryKeyPrefix`. See the API comments for more details.
-* Minimum supported version of ZSTD is now 1.4.0, for code simplification. Obsolete `CompressionType` `kZSTDNotFinalCompression` is also removed.
-
-### Behavior Changes
-* `VerifyBackup` in `verify_with_checksum`=`true` mode will now evaluate checksums in parallel. As a result, unlike in case of original implementation, the API won't bail out on a very first corruption / mismatch and instead will iterate over all the backup files logging success / _degree_of_failure_ for each.
-* Reversed the order of updates to the same key in WriteBatchWithIndex. This means if there are multiple updates to the same key, the most recent update is ordered first. This affects the output of WBWIIterator. When WriteBatchWithIndex is created with `overwrite_key=true`, this affects the output only if Merge is used (#13387).
-* Added support for Merge operations in transactions using option `TransactionOptions::commit_bypass_memtable`.
-
-### Bug Fixes
-* Fixed GetMergeOperands() API in ReadOnlyDB and SecondaryDB
-* Fix a bug in `GetMergeOperands()` that can return incorrect status (MergeInProgress) and incorrect number of merge operands. This can happen when `GetMergeOperandsOptions::continue_cb` is set, both active and immutable memtables have merge operands and the callback stops the look up at the immutable memtable.
-
-## 9.11.0 (01/17/2025)
-### New Features
-* Introduce CancelAwaitingJobs() in CompactionService interface which will allow users to implement cancellation of running remote compactions from the primary instance
-* Experimental feature: RocksDB now supports defining secondary indices, which are automatically maintained by the storage engine. Secondary indices provide a new customization point: applications can provide their own by implementing the new `SecondaryIndex` interface. See the `SecondaryIndex` API comments for more details. Note: this feature is currently only available in conjunction with write-committed pessimistic transactions, and `Merge` is not yet supported.
-* Provide a new option `track_and_verify_wals` to track and verify various information about WAL during WAL recovery. This is intended to be a better replacement to `track_and_verify_wals_in_manifest`.
-
-### Public API Changes
-* Add `io_buffer_size` to BackupEngineOptions to enable optimal configuration of IO size
-* Clean up all the references to `random_access_max_buffer_size`, related rules and all the clients wrappers. This option has been officially deprecated in 5.4.0.
-* Add `file_ingestion_nanos` and `file_ingestion_blocking_live_writes_nanos` in PerfContext to observe file ingestions
-* Offer new DB::Open and variants that use `std::unique_ptr<DB>*` output parameters and deprecate the old versions that use `DB**` output parameters.
-* The DB::DeleteFile API is officially deprecated.
-
-### Behavior Changes
-* For leveled compaction, manual compaction (CompactRange()) will be more strict about keeping compaction size under `max_compaction_bytes`. This prevents overly large compactions in some cases (#13306).
-* Experimental tiering options `preclude_last_level_data_seconds` and `preserve_internal_time_seconds` are now mutable with `SetOptions()`. Some changes to handling of these features along with long-lived snapshots and range deletes made this possible.
-
-### Bug Fixes
-* Fix a longstanding major bug with SetOptions() in which setting changes can be quietly reverted.
-
-## 9.10.0 (12/12/2024)
-### New Features
-* Introduce `TransactionOptions::commit_bypass_memtable` to enable transaction commit to bypass memtable insertions. This can be beneficial for transactions with many operations, as it reduces commit time that is mostly spent on memtable insertion.
-
-### Public API Changes
-* Deprecated Remote Compaction APIs (StartV2, WaitForCompleteV2) are completely removed from the codebase
-
-### Behavior Changes
-* DB::KeyMayExist() now follows its function comment, which means `value` parameter can be null, and it will be set only if `value_found` is passed in.
-
-### Bug Fixes
-* Fix the issue where compaction incorrectly drops a key when there is a snapshot with a sequence number of zero.
-* Honor ConfigOptions.ignore_unknown_options in ParseStruct()
-
-### Performance Improvements
-* Enable reuse of file system allocated buffer for synchronous prefetching.
-* In buffered IO mode, try to align writes on power of 2 if checksum handoff is not enabled for the file type being written.
-
-## 9.9.0 (11/18/2024)
-### New Features
-* Multi-Column-Family-Iterator (CoalescingIterator/AttributeGroupIterator) is no longer marked as experimental
-* Adds a new table property "rocksdb.newest.key.time" which records the unix timestamp of the newest key. Uses this table property for FIFO TTL and temperature change compaction.
-
-### Public API Changes
-* Added a new API `Transaction::GetAttributeGroupIterator` that can be used to create a multi-column-family attribute group iterator over the specified column families, including the data from both the transaction and the underlying database. This API is currently supported for optimistic and write-committed pessimistic transactions.
-* Added a new API `Transaction::GetCoalescingIterator` that can be used to create a multi-column-family coalescing iterator over the specified column families, including the data from both the transaction and the underlying database. This API is currently supported for optimistic and write-committed pessimistic transactions.
-
-### Behavior Changes
-* `BaseDeltaIterator` now honors the read option `allow_unprepared_value`.
-
-### Bug Fixes
-* `BaseDeltaIterator` now calls `PrepareValue` on the base iterator in case it has been created with the `allow_unprepared_value` read option set. Earlier, such base iterators could lead to incorrect values being exposed from `BaseDeltaIterator`.
-* Fix a leak of obsolete blob files left open until DB::Close(). This bug was introduced in version 9.4.0.
-* Fix missing cases of corruption retry during DB open and read API processing.
-* Fix a bug for transaction db with 2pc where an old WAL may be retained longer than needed (#13127).
-* Fix leaks of some open SST files (until `DB::Close()`) that are written but never become live due to various failures. (We now have a check for such leaks with no outstanding issues.)
-* Fix a bug for replaying WALs for WriteCommitted transaction DB when its user-defined timestamps setting is toggled on/off between DB sessions.
-
-### Performance Improvements
-* Fix regression in issue #12038 due to `Options::compaction_readahead_size` greater than `max_sectors_kb` (i.e, largest I/O size that the OS issues to a block device defined in linux)
-
-## 9.8.0 (10/25/2024)
-### New Features
-* All non-`block_cache` options in `BlockBasedTableOptions` are now mutable with `DB::SetOptions()`. See also Bug Fixes below.
-* When using iterators with BlobDB, it is now possible to load large values on an on-demand basis, i.e. only if they are actually needed by the application. This can save I/O in use cases where the values associated with certain keys are not needed. For more details, see the new read option `allow_unprepared_value` and the iterator API `PrepareValue`.
-* Add a new file ingestion option `IngestExternalFileOptions::fill_cache` to support not adding blocks from ingested files into block cache during file ingestion.
-* The option `allow_unprepared_value` is now also supported for multi-column-family iterators (i.e. `CoalescingIterator` and `AttributeGroupIterator`).
-* When a file with just one range deletion (standalone range deletion file) is ingested via bulk loading, it will be marked for compaction. During compaction, this type of files can be used to directly filter out some input files that are not protected by any snapshots and completely deleted by the standalone range deletion file.
-
-### Behavior Changes
-* During file ingestion, overlapping files level assignment are done in multiple batches, so that they can potentially be assigned to lower levels other than always land on L0.
-* OPTIONS file to be loaded by remote worker is now preserved so that it does not get purged by the primary host. A similar technique as how we are preserving new SST files from getting purged is used for this. min_options_file_numbers_ is tracked like pending_outputs_ is tracked.
-* Trim readahead_size during scans so data blocks containing keys that are not in the same prefix as the seek key in `Seek()` are not prefetched when `ReadOptions::auto_readahead_size=true` (default value) and `ReadOptions::prefix_same_as_start = true`
-* Assigning levels for external files are done in the same way for universal compaction and leveled compaction. The old behavior tends to assign files to L0 while the new behavior will assign the files to the lowest level possible.
-
-### Bug Fixes
-* Fix a longstanding race condition in SetOptions for `block_based_table_factory` options. The fix has some subtle behavior changes because of copying and replacing the TableFactory on a change with SetOptions, including requiring an Iterator::Refresh() for an existing Iterator to use the latest options.
-* Fix under counting of allocated memory in the compressed secondary cache due to looking at the compressed block size rather than the actual memory allocated, which could be larger due to internal fragmentation.
-* `GetApproximateMemTableStats()` could return disastrously bad estimates 5-25% of the time. The function has been re-engineered to return much better estimates with similar CPU cost.
-* Skip insertion of compressed blocks in the secondary cache if the lowest_used_cache_tier DB option is kVolatileTier.
-* Fix an issue in level compaction where a small CF with small compaction debt can cause the DB to allow parallel compactions. (#13054)
 * Several DB option settings could be lost through `GetOptionsFromString()`, possibly elsewhere as well. Affected options, now fixed:`background_close_inactive_wals`, `write_dbid_to_manifest`, `write_identity_file`, `prefix_seek_opt_in_only`
+* Fix under counting of allocated memory in the compressed secondary cache due to looking at the compressed block size rather than the actual memory allocated, which could be larger due to internal fragmentation.

 * Remove deprecated option `bottommost_temperature`, already replaced by `last_level_temperature`
 * Added new PerfContext counters for block cache bytes read - block_cache_index_read_byte, block_cache_filter_read_byte, block_cache_compression_dict_read_byte, and block_cache_read_byte.

With this, `GetForUpdate` skips UDT based validation and it's users' responsibility to enforce the UDT invariant. SO DO NOT skip this UDT-based validation if users do not have ways to enforce the UDT invariant. Ways to enforce the invariant on the users side include manage a monotonically increasing timestamp, commit transactions in a single thread etc.

 For Leveled Compaction users, `CompactRange()` with `bottommost_level_compaction = BottommostLevelCompaction::kIfHaveCompactionFilter` will behave similar to `kForceOptimized` in that it will skip files created during this manual compaction when compacting files in the bottommost level. (#11468)

-* Changed default block cache size from an 8MB to 32MB LRUCache, which increases the default number of cache shards from 16 to 64. This change is intended to minimize cache mutex contention under stress conditions. See https://github.com/meta/rocksdb/wiki/Block-Cache for more information.

 * For level compaction with `level_compaction_dynamic_level_bytes=true`, RocksDB now trivially moves levels down to fill LSM starting from bottommost level during DB open. See more in comments for option `level_compaction_dynamic_level_bytes` (#11321).
 * User-provided `ReadOptions` take effect for more reads of non-`CacheEntryRole::kDataBlock` blocks.
 * For level compaction with `level_compaction_dynamic_level_bytes=true`, RocksDB now drains unnecessary levels through background compaction automatically (#11340). This together with #11321 makes it automatic to migrate other compaction settings to level compaction with `level_compaction_dynamic_level_bytes=true`. In addition, a live DB that becomes smaller will now have unnecessary levels drained which can help to reduce read and space amp.

 * Refactor the classes, APIs and data structures for block cache tracing to allow a user provided trace writer to be used. Introduced an abstract BlockCacheTraceWriter class that takes a structured BlockCacheTraceRecord. The BlockCacheTraceWriter implementation can then format and log the record in whatever way it sees fit. The default BlockCacheTraceWriterImpl does file tracing using a user provided TraceWriter.

 ## Behavior Change
 * In leveled compaction with dynamic levelling, level multiplier is not anymore adjusted due to oversized L0. Instead, compaction score is adjusted by increasing size level target by adding incoming bytes from upper levels. This would deprioritize compactions from upper levels if more data from L0 is coming. This is to fix some unnecessary full stalling due to drastic change of level targets, while not wasting write bandwidth for compaction while writes are overloaded.

-# (I used a Debian system after installing docker features, adding my user to
-# the docker and docker-registry groups, and logging out and back in to pick
-# those up.)
-#
-# Meta employees: see https://fburl.com/rocksdb-docker to build this on a devvm.

-#
-# $ docker login ghcr.io -u pdillinger
