 **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

 **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>).

 - **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.
+**Avoid Premature Optimization:** While performance is critical, focus on correctness first, then optimize based on profiling data. However, be performance-aware from the start—choosing the right algorithm and data structure upfront is not premature optimization. Use the hot path analysis above to decide how much optimization effort is warranted.
 
 ### 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.

 # 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`.
-
-### 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.
-
-### 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.

 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)

 ### Behavior changes
-* 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.

-* Make kXXH3 checksum the new default, because it is faster on common hardware, especially with kCRC32c affected by a performance bug in some versions of clang (https://github.com/meta/rocksdb/issues/9891). DBs written with this new setting can be read by RocksDB 6.27 and newer.

 * 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. More details in rocksdb/includb/block_cache_trace_writer.h.

 ## 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.

-## Behavioral Compatibility Review Perspective
-
-Behavior changes are human judgment calls. They must be intentional,
-well-documented (including release notes), and researched for potential
-downstream production impact. Agents and reviewers must call out concrete gaps,
-ambiguity, or adverse impacts in the change's intent, documentation, and
-production-impact analysis.
-
-When a diff changes how an existing accepted public or serialized input is
-interpreted—including an undocumented, discouraged, or historically ignored
-value—reviewers must:
-- Compare the old and new observable behavior, including performance and
-  resource impact.
-- Check that the rationale and user-facing documentation clearly describe the
-  change.
-- Identify known direct callers and stored configurations that may depend on
-  the previous behavior.
-- Check for appropriate regression coverage, or a documented reason why such
-  coverage is not practical.
-
-A behavior change is not automatically a defect. Report a finding when the
-intent, documentation, downstream-impact analysis, or mitigation has a concrete
-gap or ambiguity that could lead to an unintended compatibility regression.
-
-## DB Mutex Review Perspective
-
-For every non-trivial change, determine whether the changed code, or any
-transitive callee it adds or changes, can run while `DBImpl::mutex_` is held.
-State the result explicitly, including when the DB mutex is not affected.
-
-`DBImpl::mutex_` is the DB-wide metadata and coordination mutex. It protects
-cross-object invariants involving `ColumnFamilyData`, memtable and
-`SuperVersion` publication, `VersionSet`, snapshots, flush/compaction queues,
-background-job state, and file lifetime. It is shared by all column families
-and can be a hot lock. It is not the filesystem `db_lock_`, and it should not
-replace data-path synchronization already provided by `WriteThread`,
-`wal_write_mutex_`, atomics, referenced `SuperVersion`s, or component-local
-synchronization.
-
-When a DB-mutex critical section is affected:
-
-### Locking and correctness
-
-- Trace the full call path and mark the exact lock and unlock boundaries. Do
-  not inspect only the lines that directly acquire the mutex.
-- State the locking contract. Helpers that require the lock should document it
-  and normally use `mutex_.AssertHeld()`. Check whether each caller expects the
-  lock to be held on return.
-- Treat calls that can release and re-acquire the mutex as concurrency
-  boundaries. Examples include `VersionSet::LogAndApply()`, condition-variable
-  waits, write-thread coordination, and notification helpers. Revalidate state
-  inspected before such a call.
-- Keep atomic metadata transitions under the mutex. Examples include moving a
-  memtable between mutable and immutable state, reserving compaction inputs,
-  installing a `Version` or `SuperVersion`, updating scheduling counters and
-  queues, and changing file-lifetime protection.
-- For expensive work, prefer a prepare/run/install structure: reserve and pin
-  the required state while locked, do CPU or I/O work while unlocked, then
-  re-lock, validate, and publish. Before unlocking, copy mutable options and
-  acquire every required object reference or lifetime reservation.
-- Check object lifetime across every unlocked region. Do not use a raw
-  `ColumnFamilyData*`, `Version*`, memtable, file metadata pointer, or DB-owned
-  container element after unlocking unless an explicit reference,
-  `SuperVersion`, job object, or pending-output reservation keeps it alive.
-- Preserve the snapshot/input-selection boundary. Flush and compaction must not
-  miss a snapshot whose visible key versions they may remove. Missing a newly
-  created snapshot is a correctness bug; retaining a recently released
-  snapshot is conservative but safe.
-- Never invoke untrusted or re-entrant code while holding the mutex. The mutex
-  is non-reentrant, so a callback into RocksDB can self-deadlock.
-- Check lock ordering. `options_mutex_` is acquired before the DB mutex. When
-  both the DB mutex and `wal_write_mutex_` are needed, the DB mutex is acquired
-  first. Establish and document the order for other locks.
-- Keep cleanup outside the critical section when possible. File deletion,
-  `JobContext::Clean()`, expensive `SuperVersion` destruction, logging, and
-  listener callbacks should normally run after protected state is detached or
-  snapshotted.
-- Do not add the DB mutex to steady-state point reads or the normal write data
-  phase without strong justification. Reads normally use a referenced
-  `SuperVersion`; writes use `WriteThread` and component-specific
-  synchronization.
-
-### Critical-section performance
-
-- Compare the CPU and I/O performed under the mutex before and after the
-  change. Include call frequency, loop bounds, input-size scaling, hidden work
-  in callees, and worst-case cost.
-- Account for filesystem or network I/O, waits, callbacks, logging and
-  formatting, allocation, container growth, copies, sorting, scans, reference
-  release and destructors, cache misses, and repeated metadata lookups.
-- Do not allow a significant regression in mutex-held work without clear
-  justification, hold-time or contention measurements, and representative
-  benchmarks.
-- Treat unavoidable work under the mutex as hot-path code and keep it highly
-  optimized. Precompute, allocate, copy, and perform I/O outside the lock;
-  remove repeated scans and lookups; cache or batch work where practical; and
-  keep locked operations O(1) or tightly bounded when possible.
-- Treat new blocking I/O, waits, callbacks into user or plugin code, unbounded
-  loops, or work that scales with DB size, files, column families, snapshots,
-  or pending jobs as a blocker unless it is unavoidable and supported by strong
-  measurements and explicit design justification.
-
-### Validation and evidence
-
-- Test unlock windows with sync points rather than sleeps. Cover relevant races
-  with memtable switches, snapshot create/release, column-family drop,
-  flush/compaction install, shutdown, and background errors. Run TSAN where
-  appropriate.
-- Distinguish wait time from hold time. `PerfContext::db_mutex_lock_nanos` and
-  `DB_MUTEX_WAIT_MICROS` primarily expose acquisition wait; use contention
-  profiles or scoped instrumentation to find long critical sections.
-- Report affected critical sections, before/after cost, workload assumptions,
-  optimization choices, and remaining risk. If exact measurement is not
-  practical, provide a conservative static bound and do not claim no regression
-  without evidence.

+# Code Review Skill
+
+This document defines the methodology for performing thorough, multi-perspective
+code reviews on RocksDB changes. It is used both by CI (GitHub Actions) and
+local review workflows.
+
+## Prerequisites
+
+Before starting a review:
+- Read `CLAUDE.md` in the repository root for project-specific guidelines
+- Read any files in `claude_md/` for architecture context
+- Identify the commit/diff/PR to review and parse the changed files
+
+## Review Methodology
+
+Conduct the review from multiple perspectives, then synthesize findings into a
+single report. Each perspective catches different classes of bugs.
+
+### Perspective 1: Codebase Context & Call-Chain Analysis
+
+Before reviewing the diff itself, build deep context:
+- For each changed function/method, trace the call chain UPWARD 3-5 levels.
+  Who consumes the changed behavior? What invariants do callers rely on?
+- Trace DOWNWARD into callees. What side effects do they have? What shared
+  state do they mutate (counters, sequence numbers, flags, metadata)?
+- Identify the "sibling" or "reference" implementation that handles the same
+  scenario the standard way. Compare behaviors.
+- For data written to shared structures (memtable, SST block, cache entry),
+  find ALL readers and verify their visibility rules match the writer.
+
+### Perspective 2: Correctness & Edge Cases
+
+- Thread safety and concurrency (lock ordering, data races)
+- Error handling and Status propagation
+- Edge cases: empty inputs, overflow, boundary conditions
+- Data corruption scenarios
+- Behavioral contract changes: do return value semantics match callers?
+
+### Perspective 3: Cross-Component & Adversarial Analysis
+
+Check the change in ALL execution contexts:
+
+| Context | Key difference |
+|---------|---------------|
+| WritePreparedTxnDB | read_callback_ controls visibility |
+| ReadOnly DB / SecondaryInstance | No mutable memtable |
+| CompactionService / Remote compaction | Different process |
+| User-defined timestamps | Extra key comparison dimension |
+| MemPurge | Memtable-to-memtable path |
+| BlobDB | Values in blob files, not inline |
+| Old snapshots | Seqno far behind current |
+| Concurrent writers | Lock-free vs locked paths |
+| FIFO / Universal compaction | Different invariants |
+| Prefix seek / total order seek | Different iterator behavior |
+
+When the change claims a property ("logically redundant", "safe because X"),
+systematically try to break it: list preconditions, construct counterexamples.
+
+### Perspective 4: Performance
+
+RocksDB is a high-performance storage engine.
+- Memory allocation on hot paths
+- Unnecessary copies (prefer move semantics, Slice, string_view)
+- Cache efficiency and data locality
+- Loop optimization, branch prediction (LIKELY/UNLIKELY)
+
+### Perspective 5: API, Compatibility & Testing
+
+- Public API backwards compatibility
+- Serialization format correctness and versioning
+- Test coverage for edge cases, failure modes, and system-level interactions
+
+## How to Explore the Codebase
+
+Use available tools to explore deeply — do NOT just review the diff in isolation.
+The most critical bugs hide at component boundaries.
+
+- Read the header files for changed implementations
+- Search for callers of changed functions (3-5 levels up)
+- Read existing tests to understand guaranteed behaviors
+- Check related implementations for conventions and patterns
+
+## Output Format
+
+### Summary
+Brief overall assessment (1-2 sentences).
+
+### Issues Found
+Categorize by severity:
+- :red_circle: **Critical**: Must fix (correctness, data corruption, security)
+- :yellow_circle: **Suggestion**: Should consider (performance, edge cases)
+- :green_circle: **Nitpick**: Minor style issues
+
+For each issue include:
+- File and line reference
+- Which review perspective found it
+- Description with root cause analysis
+- Suggested fix
+
+### Cross-Component Analysis
+Execution context checks and assumption stress-test results.
+
+### Positive Observations
+Good patterns, clever optimizations, or improvements.

-# Manual (Local) Code Review — Lightweight Wrapper
-
-## What this is
-
-A resource-light, **single-reviewer** variant of `claude_md/ci_review_prompt.md`
-for running a review by hand in a local Claude Code / Devmate session. It reuses
-the full CI review *methodology* but drops the multi-agent orchestration and the
-CI-only file-persistence machinery, to approximate the heavyweight result at a
-fraction of the cost.
-
-**Scope: LOCAL manual review only. This file is NOT used by CI.** CI uses
-`claude_md/ci_review_prompt.md`.
-
-## How to use
-
-Read `claude_md/ci_review_prompt.md` for the complete methodology — the analysis
-techniques (caller-chain, callee side-effects, cross-component data consumers,
-alternative execution contexts, assumption stress-testing), the per-perspective
-reviewer instructions, the review checklist, and the anti-patterns table.
-
-Then apply that methodology with the OVERRIDES below. **Where this file
-conflicts with `ci_review_prompt.md`, this file wins.**
-
-## Overrides (this is what makes it lightweight)
-
-### 1. Single reviewer — no team, no subagents
-- Do NOT create a team, spawn subagents, or run parallel/background agents.
-- Do NOT run the round-robin Debate phase or the Consensus phase.
-- Instead, YOU personally apply each reviewer role from `ci_review_prompt.md`
-  (Design, Correctness, Cross-Component & Adversarial, Invariant Adversary,
-  Caller-Context, Performance, API/Compat, Serialization, Test Coverage) as
-  sequential *lenses* in one pass. Spend a few focused minutes per lens. Skip
-  lenses that plainly don't apply (e.g., Serialization when there is no on-disk
-  or wire-format change) and note the skip in one line.
-
-### 2. No intermediate files
-- Do NOT write `context.md`, `findings-*.md`, `consensus.md`, or
-  `review-findings.md`. Keep working notes in your reasoning, not on disk.
-- Rationale: those files exist only so CI can recover partial results when an
-  ephemeral runner hits the turn limit — a local session has neither problem.
-  `ci_review_prompt.md` already outputs the review as its final response, so
-  skipping the file loses nothing here.
-
-### 3. Right-size the effort
-- Do the Codebase Context phase, but proportionally: trace the 2-3 most
-  load-bearing call chains and the highest-risk cross-component data consumers,
-  rather than exhaustively enumerating every caller 3-5 levels up.
-- Prioritize the highest-signal lenses for RocksDB: **Correctness**,
-  **Cross-Component & Adversarial**, and **Assumption Stress-Testing**. These
-  catch the bugs that matter most; give them the most attention.
-- Escalation clause: if a thread looks dangerous, go deep on that specific
-  thread even though the overall pass is modest. Modest is the default, not a cap.
-
-### 4. Identify the review target locally
-- Unlike CI, the diff is NOT pre-pasted into this prompt. Determine what to
-  review from the user's request against the local worktree — e.g. the current
-  commit (`git show`), uncommitted changes (`git diff` / `git diff --staged`),
-  a named commit range, or a PR — and read the changed files plus their
-  surrounding context directly from the repo. When in doubt, include all changes
-  not yet upstream, as in
-  `git diff "$(git merge-base upstream/main HEAD 2> /dev/null || git merge-base origin/main HEAD 2> /dev/null)"`
-  plus any untracked files (`git status`) that seem relevant.
-
-## Reminder
-
-The goal is a thorough *single* reviewer, not a 9-agent debate: depth where it
-matters, brevity everywhere else.

-# RocksDB Diff and Pull Request Summary Guidance
-
-This guidance applies to both internal Phabricator diff summaries and external
-GitHub pull request summaries for changes under `fbcode/internal_repo_rocksdb/`.
-
-## Goal
-
-Write each diff or pull request summary for a reviewer who has not read the
-patch. The summary must explain the behavioral story and the evidence for it,
-not merely inventory the edited files or symbols.
-
-Every new or updated diff or pull request summary must clearly cover:
-
-1. Why the change is required.
-2. What the previous behavior was, including the failure mode or limitation.
-3. What the new behavior is.
-4. What changed in the implementation.
-5. Safety boundaries, compatibility, and unsupported or intentionally deferred
-   cases.
-6. Tests performed and known limitations of the validation.
-
-Use explicit headings for a broad, subtle, or high-risk change. A small,
-focused change may combine these points into a few paragraphs, but none may be
-left implicit when it affects a review decision.
-
-## What Good RocksDB Summaries Make Concrete
-
-- Name the exact conditions that activate a bug or behavior: relevant options,
-  call ordering, storage mode, concurrency mode, file format, platform, or
-  workload shape. Also state important cases that are not affected.
-- Explain the causal chain from the old behavior to its externally observable
-  result. For correctness fixes, distinguish a symptom from the underlying
-  invariant violation.
-- Describe the new contract before implementation mechanics. Then identify the
-  essential implementation choices and why they are sufficient.
-- Call out API, ABI, serialized-format, behavioral, and performance
-  compatibility where relevant. For additive persisted fields, state how older
-  data is interpreted and whether older readers remain supported.
-- State safety boundaries precisely: defaults, feature gates, fallback paths,
-  ownership and lifetime constraints, memory-ordering assumptions, and cases
-  deliberately postponed to a follow-up.
-- Support performance claims with a baseline, workload and configuration,
-  measurement method, and results. Report meaningful tradeoffs, not only the
-  winning metric.
-- Make the test plan evidence-based. Name the tests and configurations, say
-  what behavior each proves, and report failures, timeouts, untested platforms,
-  or stale pre-rebase results honestly. For a regression test, say how it fails
-  without the fix when that was verified.
-- Separate incidental cleanup or a pre-existing test fix from the primary
-  change, and explain why it belongs in the diff.
-
-Avoid vague claims such as "improves performance," "fixes an issue," or "tests
-pass." Avoid copying the patch into prose, exhaustive file-by-file narration,
-raw command output, and claims broader than the evidence.
-
-## Suggested Structure
-
-Adapt this structure to the change; do not keep empty or irrelevant sections.
-
-```text
-Summary:
-
-Why the change is required:
-<User or system impact, and why the current behavior is inadequate.>
-
-Previous behavior:
-<Old contract or mechanism, triggering conditions, and observable result.>
-
-New behavior:
-<New contract and externally visible effect.>
-
-Implementation:
-<Essential design and code changes; omit routine edit-by-edit narration.>
-
-Safety, compatibility, and limitations:
-<Defaults, unaffected paths, compatibility, unsupported cases, and follow-ups.>
-
-Test Plan:
-<Exact tests/benchmarks, configurations, what they demonstrate, and gaps.>
-```
-
-For a focused bug fix, a cohesive narrative can be clearer than six headings:
-problem and root cause, trigger and unaffected cases, fix, then quantified or
-counterfactual validation. For a multi-part change, labeled bullets such as
-`Fix`, `Add`, and `Change` can make the implementation and review surface easy
-to scan.
-
-## Reference Pull Request Summaries
-
-- [PR #15216](https://github.com/meta/rocksdb/pull/15216) is a strong
-  focused bug-fix example. It traces stale iterator state to readahead behavior
-  and dropped keys, identifies the exact prerequisites and unaffected mmap
-  case, gives before/after measurements, and explains how the regression test
-  fails when the fix is reverted.
-- [PR #15218](https://github.com/meta/rocksdb/pull/15218) is a concise
-  example of explicit `Why`, `Previous behavior`, `New behavior`,
-  `Implementation`, and `Safety boundaries and unsupported cases` sections.
-- Peter Dillinger's [PR #15231](https://github.com/meta/rocksdb/pull/15231)
-  is a strong recent multi-part example. Its `Fix`/`Add`/`Change` bullets
-  separate the behaviors, its compatibility sentence explains how old files
-  read back, and its test plan maps each new persisted property to concrete
-  coverage while explaining an adjacent test adjustment.
-
-Use these pull requests as models for reasoning, specificity, and evidence. Do
-not copy their length or headings mechanically; scale the summary to the risk
-and complexity of the change.
