continuousBackup integration suite: stop each engine before its directory is removed.

Three tests registered the hook that removes their temp directory before the hook
that stops their engine. node:test runs after-hooks in the order they were
registered, not last-in first-out, so the directory was gone when stop() sealed
into it, and the ENOENT (files/index.ndjson) surfaced after the test as
"generated asynchronous activity after the test ended" - which failed the whole
suite although all 8 tests passed. One hook now stops the engine first and then
removes the directory. Five runs in a row, and the suite runner, pass.

Thanks to xet7 !

-# v12.77 2026-10-31 WeKan ® release
+# Upcoming WeKan ® release
 
-Two **node test guards** follow the movable popups and the date
-picker of v12.76.
+**Continuous backup** now runs on one server at a time, with a
+lease, when WeKan has
+several servers. Missing-board **exports** and **integration updates** answer
+404 instead of 200, a
+card stops offering the attachment "+" when uploads are blocked, and the Docker
+image's **nodemailer**,
+**body-parser**, **qs**, **uuid** and **postcss-selector-parser** are raised
+past the advisories a Grype
+scan found.

-# v12.76 2026-10-31 WeKan ® release
+# v12.94 2026-11-04 WeKan ® release
 
-Security features: a **password policy** with an optional
-breached-password check, **Admin Panel / Problems / Password length**,
-**compulsory two-factor authentication**, sign-out of **idle sessions** and of
-every session after a password change, an **audit log** of what administrators
-did, **HSTS**, a cross-site request guard, and **S3 encryption at rest**.
-**Sign-up** works again; the date picker has **Today**, the whole card title
-edits and **every popup can be moved**; and an old **Sandstorm** grain migrated
-from MongoDB 3 shows its boards again.
+On an iPad the **opened card covers the header bar** instead of
+sitting
+behind it, and the speed test measures where the time goes when a WeKan board is
+opened, on FerretDB and on MongoDB.

-# v12.75 2026-10-30 WeKan ® release
+# v12.93 2026-11-04 WeKan ® release
 
-Changing a password signs the account out in every other browser,
-and now a test proves it in two real browsers.
+The database **speed test** has a new small-scale result, ordered
+from fastest to slowest with how many times slower each database is, and two
+more databases: **pgrust** (PostgreSQL in Rust) and **TiDB**. Noria, YugabyteDB
+and CockroachDB were looked at and cannot be used, for reasons the README gives.

-# v12.74 2026-10-30 WeKan ® release
+# v12.92 2026-11-03 WeKan ® release
 
-**Caddy** and **FerretDB**, the Go servers WeKan ships, no longer
-open MPTCP listeners, which Linux kernel bug **CVE-2026-98432** is reachable
-through. The real fix is a patched host kernel.
+A missing **REST checklist** answers a JSON 404 instead of an
+empty 500.

+[All changes in v12.92](CHANGELOG-big.md#v1292-2026-11-03-wekan--release)
 
-# v12.73 2026-10-30 WeKan ® release
+# v12.91 2026-11-03 WeKan ® release
 
-**CHANGELOG.md** is now short: the In short of the upcoming
-release and of the five newest releases, in plain Markdown. The status and every
-change of each release are in **CHANGELOG-big.md**, which is the one that is
-written. **CodeQL** alert #598 in the Sandstorm host test is fixed, and the
-release script pulls before releasing, so a moved main no longer stops it.
+A **GitHub CodeQL** finding in a test is fixed, and the guard
+against
+replacing text with itself now also sees patterns with a `^` or `$` anchor.

+## Several servers: one of them streams
+
+When WeKan runs as several servers on one database (for example the replicas of a Kubernetes
+Deployment), **one of them runs the stream** and the others stand by
+([#6861](https://github.com/wekan/wekan/issues/6861)). They coordinate through a *lease*: one
+document, `continuousBackupLease`, holding the leader's id and an expiry.
+
+- Every server with the feature switched on tries to take the lease. Taking it is one atomic
+  database operation, so two servers can never both lead.
+- The leader renews it every 15 seconds. It lapses 45 seconds after the last renewal, so when the
+  leader stops (a pod restart, a rollout, a crash) another server takes over within about a minute
+  and continues from the position the stream saved in the target.
+- A server that finds it has lost the lease stops its stream, so two never write one target.
+- Saving the settings, switching the feature off and on, and a change saved on another server all
+  converge through the same loop: the leader follows the change on its next tick.
+- A restore, and *fetch from the cloud*, must be the only writer: they take the lease from whoever
+  holds it and wait one renewal, so the former leader has stopped before anything is written. The
+  stream resumes through the loop afterwards.
+
+An installation with one server is always its own leader, so nothing changes for it. The target
+directory is still one place: with several servers it must be on storage they all reach (a shared
+volume, NFS, an [rclone mount](Rclone/Rclone.md)), or the server that takes over starts a new
+generation instead of continuing.

+
+**FerretDB on SQLite**
+
+- **SQLite sorts in the database** (v1.100.0). A sorted query used to read,
+  decode and keep every matching document in Go to return a few - People's ten
+  newest users, the first page of a list. SQLite now orders the row ids by a key
+  that reproduces MongoDB's order for simple values, and documents are fetched a
+  batch at a time in that order: the ten newest of 30,000 users allocate 2.6 MB
+  instead of 264 MB. A document whose sort field holds an array, a document, NaN
+  or an infinity comes first, and then everything is sorted in Go as before, so
+  the answer is the same. The key is read once per row, in one JSON path.
+- **Documents are stored as SQLite JSONB** (v1.101.0). Every filter, sort key,
+  index and multikey trigger used to parse the JSON text of a document again.
+  New collections are binary, and an existing database is converted once when
+  it is opened, table by table in a transaction (204,212 documents took 81 s; a
+  table that fails stays text and keeps working). On 61,507 cards, due cards went
+  from 1,003 to 519 ms, All Boards from 95 to 42 ms and creating the 44 indexes
+  from 107 to 70 s. After the conversion an older FerretDB cannot read the
+  database.
+- **`distinct` works when documents lack the field** (v1.105.0), which a database
+  migrated from MongoDB 3 needs on its first start.
+
+- **A membership test reads the array from the column, not from the text of `->`**
+  (found by profiling Due Cards, fixed after v1.105.0). `{members: {$elemMatch:
+  {userId: X}}}` was `json_each(col->"members")`: `->` renders the whole array as
+  JSON text and `json_each` parses that text again, for every row. It is now
+  `json_each(col, '$."members"')`, which SQLite walks in place. The visible-boards
+  query went from 26.2 to 15.7 ms on 2,308 boards, and in the speed test All Boards
+  count from 6.9 to 4.9 ms, All Boards page from 5.9 to 3.9 ms and Due Cards from
+  54.5 to 43.9 ms (the SQLite total 82.7 → 68.3 ms); the 169 answers of 12 queries
+  are identical to before.
+
+**FerretDB on PostgreSQL**
+
+- **Membership tests use a GIN index** (v1.100.0): an index whose leading key is
+  `ARRAY.FIELD` (`members.userId`) also gets a `jsonb_path_ops` GIN index of the
+  array, and `{members: {$elemMatch: {userId: X}}}` uses it.
+- **`$or` and `$elemMatch` are conditions in the database** (v1.101.0), so Due
+  Cards' query went from 2,031 to 815 ms on 61,507 cards.
+- **A top-level `$and` is pushed down** (v1.100.0). WeKan's Due Cards wraps its
+  conditions in one, and every document was read.
+
+- **A table is analyzed once its indexes are created** (found by the small run,
+  fixed after v1.105.0). PostgreSQL has statistics for an expression index
+  (`_jsonb->'field'`) only after `ANALYZE`, which autovacuum runs a minute or
+  more after a bulk load. Before that the planner guessed **one row** for a Due
+  Cards query that returns 2,000, and chose a plan with no parallelism: 407 ms
+  on 15,377 cards, 84 ms after. The whole PostgreSQL row went from 454 ms to
+  145 ms and from last place to eighth. The same `ANALYZE TABLE` was tried on
+  MySQL and MariaDB and made no difference (100 and 279 ms before, 106 and 283
+  after), so it was not kept.
+
+**FerretDB on MySQL and MariaDB**
+
+- **Reads use their indexes** (v1.100.0): an equality or `$in` narrows through
+  the index's generated column. A card by `_id` among 615,070 went from 3.4 s
+  (MySQL) and 18.7 s (MariaDB) to 1.8 ms. Generated columns are `VIRTUAL`, so
+  adding the 44 indexes of a 600,000-document database takes 157 s, not 20
+  minutes; an index of four or more fields indexes prefixes, so it fits the
+  3,072-byte key limit that three of WeKan's compound indexes used to exceed;
+  and a path with a dash or a digit (`services.accounts-lockout.unlockTime`, `profile.emailBuffer.0`) no longer
+  fails with "Invalid JSON path expression".
+- **Multikey side tables** (v1.100.0), as on SQLite, so a membership test reads
+  only the matching documents. Without the right to create triggers (MySQL with
+  binary logging and no SUPER) nothing is created and queries read as before.
+- **An `$or` of `_id` sets is one `UNION ALL`** (v1.100.0): All Boards for a user
+  with a starred board went from 900 ms (MySQL) and 5.7 s (MariaDB) among 92,000
+  boards to 6-7 ms.
+- **A long `$in` is one `IN`** (v1.101.0), not 2,596 `JSON_CONTAINS` in an OR
+  (52 million comparisons over 20,000 cards).
+- **Updates and deletes by `_id` use the `_id` index** (v1.99.0, listed above).
+
+**WeKan** - less work for the database, which matters more the bigger it is:
+
+- **Collection scans are gone from the hourly and startup paths.** The recurring
+  cards job has a partial index on `recurrenceInterval` (it read 1,108,017 cards
+  in 1,155 ms every hour); search sessions have the indexes their upsert and
+  lookup use, and the stale sessions of every user are removed (one instance had
+  4,751 taking 10 GB); the board key backfill is one `$in` on the key index; the
+  list sync scan and the due-date lookup have partial and sparse indexes.
+- **One server does it, not all of them.** The startup schema re-check is claimed
+  in `_wekan_migration`, the daily due-date reminder scan and the database
+  health probe are claimed per period, so 24 replicas no longer scan, send or
+  report 24 times.
+- **Admin Panel / Problems / Database** reports what makes an instance slow: a
+  query that read a whole collection of at least 10,000 documents (which
+  collection, the command, the operators per field and the `queryHash`), and a
+  high read rate. The speed test's Due Cards and All Boards numbers say what a
+  query costs on one database; this says which query an instance is actually
+  asking.
+
 ## What could still be improved
 
-- **Sorting and `limit` in the database.** FerretDB v1 sorts in Go: People's ten
-  newest users, All Boards' first page and a card window read and sort every
-  matching document. Pushing an ORDER BY down needs MongoDB's ordering across
-  types, missing fields and arrays to be exact in SQL.
+- **Due Cards on SQLite, 44 ms of the 68 ms total.** A CPU profile of FerretDB
+  while it ran Due Cards (taken before the change above): half the CPU was inside
+  SQLite, and about a fifth of all of it converting JSON between binary and text
+  (`_jsonTranslateBlobToText` 10%, `_jsonTranslateTextToBlob` 10%, besides
+  `_jsonLookupStep`); another quarter was Go runtime (thread signalling,
+  `madvise`, the network poller). Of the cards query's 24 ms, 18 ms is the index
+  lookups (the 700-board `IN` list) and 6 ms the five per-user conditions
+  (`members`, `assignees`, `requesters`, `assigners`, `userId`), each of which
+  evaluates `->` three times per row. Reading each once, as
+  `json_type(col,'$."f"') = 'array' OR col->>'$."f"' = ?`, took that step from
+  24.4 to 20.5 ms with the same rows - **not done**, because it may only be applied
+  to a field no index covers (an index is matched by the expression `col->"f"`),
+  and FerretDB's WHERE builder does not know which fields are indexed.
+- **Tried on SQLite and not worth it, or not conclusive**: `ANALYZE` made no
+  difference (FerretDB chooses its indexes itself); a Unix socket instead of TCP
+  saves about 0.05 ms (20%) on a point read (0.24 → 0.19 ms), which is free when
+  WeKan and FerretDB share a machine (`--listen-unix`); `GOGC=400` gave 10-15% on
+  some queries in one test (board cards 5.3 → 4.4 ms) and nothing in another that
+  also set a memory limit, so it is a lead, not a result.
+
 - **The busiest users.** What remains of All Boards for a member of thousands of
-  boards, and of Due Cards, is decoding those boards and sorting them in Go.
-- **SQLite stores JSON as text.** Every `->` parses the document again - which is
-  also why creating an index takes 19 minutes for SQLite and 115 s for PostgreSQL,
-  whose `jsonb` is binary. Storing SQLite's JSONB would remove that, but changes
-  the storage format and needs a migration.
-- **Multikey indexes for PostgreSQL, MySQL and MariaDB.** Only SQLite has the side
-  tables; All Boards takes 8-9 s on the others.
-- **MySQL and MariaDB reads do not use their indexes**: equality is
-  `JSON_CONTAINS(JSON_EXTRACT(doc, ?))`, so a card by `_id` takes 3.4 s and 18.7 s
-  (and an edit as long - it reads the card first). Their indexes are generated
-  `VARCHAR(255)` columns added with a table rebuild each (20 and 40 minutes for
-  44 indexes; VIRTUAL columns would avoid the rebuild), and three of WeKan's
-  compound indexes exceed the 3,072-byte key limit and are not created.
+  boards, and of Due Cards, is decoding those boards and sorting them in Go on
+  the databases that do not sort in SQL.
+- **Sorting in the database on PostgreSQL, MySQL and MariaDB.** Only SQLite does
+  it. PostgreSQL was tried (2026-11-03): an `ORDER BY` of type class, number and
+  text (`COLLATE "C"`, MongoDB's byte order) with the documents that cannot be
+  ordered first, as on SQLite, and the tests matched the Go sort over mixed
+  types. It was **not faster**: the ten newest of 30,116 users took 52 ms, against
+  38-49 ms for fetching, decoding and sorting them in Go, because the Go path is
+  already fast after the decoding changes and the sort expressions cost about as
+  much. It would only save memory and transfer, so it was not kept. A sort that
+  wins needs an expression index on the sort field, which has to know the field
+  in advance; MySQL and MariaDB have the same cost structure and no measurement
+  that says otherwise.
+- **MariaDB stores JSON as text** that every JSON function parses again, so it
+  keeps only what an index answers (`$or` and `$elemMatch` are not pushed down).
 - **Existing MySQL/MariaDB tables** keep their case-insensitive index columns
   until rebuilt.
+- **Measuring it again at full scale.** Results.md is scale 0.05. A full-scale
+  run (`WEKAN_SPEEDTEST_SCALE=2`, hours) would show the busiest users, where the
+  differences are largest.
+
+## Other databases tried
+
+Asked for: any other fast database that FerretDB can use and that is open source.
+FerretDB v1 has handlers for PostgreSQL, MySQL, SQLite and SAP HANA, so a
+candidate has to speak one of those protocols **and** run the SQL the handler
+writes: `jsonb` expression indexes, `@>` and GIN on PostgreSQL; `JSON`,
+`JSON_EXTRACT`, generated columns and triggers on MySQL.
+
+| Database | Result |
+| --- | --- |
+| [pgrust](https://github.com/malisper/pgrust) v0.4-beta (PostgreSQL in Rust, AGPL-3.0) | **Works**, same answers as MongoDB, and is in Results.md. It is not faster than PostgreSQL for WeKan's queries: 174 ms against 145 ms in total, and creating the 47 indexes takes 38 s against 1 s. |
+| [TiDB](https://github.com/pingcap/tidb) 7.5 (Apache-2.0, MySQL protocol) | **Works**, same answers, and is in Results.md (240 ms, between pgrust and MariaDB). It needed one change in FerretDB: its metadata table's generated columns are `VIRTUAL`, because TiDB refuses `ALTER TABLE ... ADD COLUMN ... STORED`. This is one process with its own storage; a real cluster (PD and TiKV) is a different test. |
+| [Dolt](https://github.com/dolthub/dolt) 2.6.2 (git for data, Apache-2.0, MySQL protocol) | **Works with the existing MySQL handler, no new handler**, same answers as MongoDB, and is in Results.md - and is **by far the slowest: 20,470 ms in total, 1,230x MongoDB**. Every query over cards takes about 2.8 s on 15,377 cards (a whole-table scan, about 187 µs a document: the generated-column indexes the handler relies on do not narrow a read there), All Boards 850 ms, and creating the indexes 106 s. Its point is version history, not speed; see [VersionHistory](../VersionHistory/). |
+| [Noria](https://github.com/mit-pdos/noria) (MIT research prototype, Apache-2.0) | **Cannot run FerretDB.** It is a streaming dataflow system that precomputes the results of a fixed set of prepared queries. Its SQL has no `JSON` type (the parser's type list is `INT`, `VARCHAR`, `TEXT`, `BLOB`, `DATE`, ...), no triggers and no generated columns, and the MySQL handler needs all three: it uses `JSON` 79 times, `JSON_EXTRACT` 74 times and 7 generated columns. It also needs unpinned nightly Rust (2021) and ZooKeeper, and has not changed since October 2021. Not built or run. |
+| [YugabyteDB](https://github.com/yugabyte/yugabyte-db) 2026.1.2 (core Apache-2.0, PostgreSQL 15 compatible) | **Cannot run FerretDB.** Started, and FerretDB's first `CREATE INDEX` fails: `INDEX on column of type 'JSONB' not yet supported`. Every FerretDB v1 index on PostgreSQL is an expression of type `jsonb`, and so is every query that uses one; YugabyteDB can index a `jsonb` column only with GIN. Supporting it means writing the indexes and conditions as `->>` text, which is a different handler. |
+| [CockroachDB](https://github.com/cockroachdb/cockroach) | **Not tried: not open source.** Its LICENSE is the proprietary CockroachDB Software License, not an open-source one. |
+
+Tried with the MySQL handler, to see how far it gets (both speak the MySQL protocol):
+
+| Database | Result |
+| --- | --- |
+| [ClickHouse](https://github.com/ClickHouse/ClickHouse) 26.10 (Apache-2.0) | **Needs a handler of its own.** The first statement FerretDB sends through its MySQL interface fails: `sql: expected 0 arguments, got 2`. Behind that it has no `JSON_EXTRACT`, `JSON_CONTAINS`, triggers or generated columns as the handler uses them (it has `JSONExtract*`), and a row update is an asynchronous mutation, which is not what WeKan's edits and moves are. |
+| [StarRocks](https://github.com/StarRocks/starrocks) 4.1 (Apache-2.0) | **Needs a handler of its own.** The first `CREATE TABLE` fails: `Data type of first column cannot be JSON`; its tables need a key column and a distribution. An analytical engine again, with no triggers. |
+
+A handler for either is a new backend of the size of the SAP HANA one (about
+2,000 lines of Go: query, insert, update, delete, indexes, statistics) plus its own
+SQL for every filter FerretDB can push down; without the pushdown a query reads
+the whole collection, which the speed test would measure as slow. That has not
+been written. Not tried at all: DuckDB (no server; the Go driver needs cgo, which
+FerretDB's builds do not use) and SingleStore (not open source, and its image
+needs a licence key). A MongoDB-protocol database needs no FerretDB and joins the
+MongoDB rows; FerretDB 2 with DocumentDB is already there.
+
+## Opening a board in WeKan
+
+The same databases, one level up: [app/](app/) opens a WeKan board of 200, 2,000 and
+5,000 cards on FerretDB (SQLite) and on MongoDB 8 and profiles both the Meteor server
+and FerretDB. The Meteor server's CPU is the same on both (0.1-0.5 s); on a 5,000-card
+board FerretDB (SQLite) takes **400-600 ms longer** (to the first card +42-48%), a
+small board only 70-100 ms, and it uses about 4 s of CPU to open the 5,000-card board,
+a third of it filtering in Go what it read; the browser receives the same ~210 KB at
+every size.
+
+## Go databases linked into FerretDB
+
+Could a database implemented in Go be linked into the FerretDB binary beside its
+SQLite, and be faster? [embedded/](embedded/) asks that of the
+[awesome-go list](https://github.com/avelino/awesome-go#databases-implemented-in-go):
+Pebble, Badger, bbolt, BuntDB, Nutsdb and Clover against SQLite set up as FerretDB
+sets it, on the speed test's cards, in minutes. **None is faster where it counts**:
+a board's cards take the same time on every engine that is not slower, because
+decoding the JSON dominates; the key-value stores win single reads and writes by
+microseconds that the 0.2 ms floor of a FerretDB call hides, and would make the
+handler do in Go what SQL does in SQLite. bbolt with its default fsync is 100-160x
+slower on writes, Pebble 12x slower on fetching a board, Clover 90-190x slower.

+# Opening a WeKan board: where the time goes
+
+The [speed test](../) asks the database alone. This asks what a person waits for: the
+whole of opening a board in WeKan, with WeKan on FerretDB (SQLite) and on MongoDB 8,
+and how much of it is the database. [board-open.cjs](board-open.cjs) seeds a board of
+N cards, logs in, opens it in Chromium and records
+
+- the wall clock to the first minicard and until the DDP WebSocket has been quiet for
+  1.5 s (**settled**), and what crossed the WebSocket;
+- the Meteor server's CPU, by who spends it (a Node inspector profile of the server);
+- FerretDB's CPU (its pprof), against what it spends with nobody in the browser.
+
+```sh
+# WeKan on FerretDB: MONGO_URL=mongodb://127.0.0.1:27040/wekan?directConnection=true,
+# DEFAULT_METEOR_REACTIVITY_ORDER=polling (as WeKan is deployed), meteor run --inspect=9229,
+# and FerretDB with --debug-addr=127.0.0.1:8098
+WEKAN_BASE_URL=http://localhost:3310 WEKAN_MONGO_URL=mongodb://127.0.0.1:27040/wekan \
+  node docs/Databases/FerretDB/1/SpeedTest/app/board-open.cjs --sizes 200,2000,5000 \
+    --inspect 9229 --ferret-pprof http://127.0.0.1:8098 --label ferretdb-sqlite
+```
+
+Run on 2026-11-03/04, Apple M2 Max, **the development build of Meteor** (so the browser's
+own part is larger than in production), one user, `polling` reactivity, FerretDB v1.105.0
+with the SQLite membership-test change, MongoDB 8.0 in Docker. Each board is opened
+twice (the second is warm), and the whole measurement was run **twice** (run 1 / run 2
+below), because one run is not enough: the same board's "settled" time moved by up to
+300 ms between runs.
+
+## Result: the database is not what you wait for on a small board, and is on a big one
+
+Milliseconds, first open of a board with this many cards (run 1 / run 2). WeKan loads
+cards lazily, so the browser gets **the same ~210 KB and draws 70-120 minicards at every
+size**.
+
+| Cards | FerretDB (SQLite): first card | settled | MongoDB 8: first card | settled |
+| ---: | ---: | ---: | ---: | ---: |
+| 200 | 750 / 764 | 966 / 880 | 752 / 698 | 865 / 813 |
+| 2,000 | 931 / 1,031 | 1,763 / 1,555 | 829 / 856 | 1,457 / 1,582 |
+| 5,000 | 1,331 / 1,334 | 2,166 / 2,065 | 938 / 899 | 1,562 / 1,622 |
+
+What is the same in both runs:
+
+- **5,000 cards: FerretDB is 400-600 ms slower**, to the first card by 42-48% and until
+  settled by 27-39%.
+- **2,000 cards: within the noise** for "settled" (-30 to +300 ms), and 100-175 ms
+  slower to the first card.
+- **200 cards: 70-100 ms**, which is 9-12%.
+
+The warm second open of run 2: 5,000 cards 1,321 against 865 ms to the first card
+and 1,946 against 1,594 ms settled; 2,000 cards 904 against 824 and 1,628 against
+1,446; 200 cards 721 against 689 and 934 against 805.
+
+The Meteor server's CPU is the same on both databases within the noise (first open, run
+1 / run 2: 102 / 119, 276 / 421 and 470 / 517 ms on FerretDB; 178 / 93, 245 / 342 and
+521 / 483 ms on MongoDB), so the difference is **time spent waiting for the database**,
+and it grows with the size of the board while the data the browser receives does not.
+
+For a board of a few hundred cards, 0.7-0.75 s to the first card is nearly the same on
+both: that is the application (the development bundle, Blaze, the DDP round trips), not
+the database.
+
+## Where the Meteor server spends its CPU (5,000 cards, first open, run 2)
+
+| | FerretDB (517 ms) | MongoDB 8 (483 ms) |
+| --- | ---: | ---: |
+| Garbage collector | 31% | 24% |
+| MongoDB driver (wire, decode, encode) | 19% | 22% |
+| Meteor mongo (observers, polling, diff) | 12% | 13% |
+| Node internals | 11% | 12% |
+| WeKan code | 11% | 10% |
+| Other Meteor packages and dependencies | 8% | 9% |
+| Native, EJSON, DDP server (publish, mergebox) | 8% | 10% |
+
+The DDP server itself, publish and mergebox, is 1%. The largest single functions are
+the garbage collector, `CollectionDocument` (WeKan's model class), `replaceTypes`
+(Meteor's BSON-to-EJSON step) and the BSON decoder.
+
+## Where FerretDB spends its CPU
+
+With nobody in the browser FerretDB uses 110-510 ms of CPU in the 14 s window the
+profile covers. Opening a board adds, net: about nothing at 200 cards, **about 1.6 s at
+2,000 and about 3.9-4.1 s at 5,000** - eight times the Meteor server's CPU for the same
+open. For the 5,000-card board, of 4.41 s (run 2):
+
+- the SQLite engine, 1.72 s (39%), a good part of it moving through the pages of the
+  cards table (`btreeInitPage` 18% by itself);
+- 34% is `filterIterator.Next`: documents read from SQLite and filtered again in Go;
+- by MongoDB command: `find` 0.79 s, `getMore` 0.74 s, `aggregate` 0.68 s (a `$group`
+  done in Go over the documents it read);
+- the Go garbage collector, 0.57 s (13%).
+
+Which WeKan query sends the `aggregate` during the open was **not identified**; the
+debug log of a 2,000-card open contains none, so the 5,000-card profile may have
+included the All Boards page's card counters (`getAllBoardsTileData`, a `$group` over
+the user's boards) that the login lands on first. Treat that line as a lead.
+
+## What this does and does not say
+
+- It says the database layer is the part of opening a board that **scales with the board
+  size**, and that on FerretDB (SQLite) a 5,000-card board takes 400-600 ms longer than on
+  MongoDB, with the same data sent to the browser.
+- It says the **Meteor server is not the bottleneck**: 0.1-0.5 s of CPU, the same on both
+  databases, and the DDP server is about 1% of it. A backend rewritten in another language
+  could save a part of that, and would not change the database or the browser.
+- It does not separate the browser's own time from the wait for the server: the first
+  card at 0.7 s on a small board is mostly the development bundle and rendering.
+- Single machine, the development build, one user, two runs, two opens per board, `settled`
+  meaning 1.5 s without a DDP frame. A production build and a loaded server would differ.

+# Go databases that could be linked into FerretDB, against its SQLite
+
+FerretDB is one Go binary, and its SQLite handler is the pure-Go driver
+[modernc.org/sqlite](https://gitlab.com/cznic/sqlite) inside it. Is any database
+implemented in Go (the [awesome-go list](https://github.com/avelino/awesome-go#databases-implemented-in-go))
+one that could be linked in beside it, has enough to take SQLite's place, and is

+
+**Short answer: no. Nothing is faster in a way that matters, and the ones that are
+faster at a single read or write are key-value stores that would make the handler
+do SQLite's job.**
+
+This is the engine level of the question, so it can be answered in minutes and
+without writing a handler for each: [bench.go](main.go) loads the speed test's cards
+and asks each engine the questions WeKan asks of cards, the way a FerretDB handler
+written for it would ask them.
+
+```sh
+node docs/Databases/FerretDB/1/SpeedTest/embedded/export.cjs 0.05 <dir>   # the speed test's cards as JSON lines
+cd docs/Databases/FerretDB/1/SpeedTest/embedded && go run . -data <dir>   # go 1.24+, pure Go, no cgo
+```
+
+Run on 2026-11-03 on an Apple M2 Max, Go 1.27, one engine at a time, each in its own
+directory. `-only "Pebble (CockroachDB's LSM),Nutsdb"` runs some.
+
+## What is asked
+
+| Column | The question |
+| --- | --- |
+| By id | one card by `_id` |
+| Board cards | the unarchived cards of a board (an index on boardId and archived), **decoded** from JSON as FerretDB must |
+| (raw, not decoded) | the same fetch without the decoding: the part that differs between engines |
+| Count | how many unarchived cards a board has |
+| Edit, Move | read the card, change it in Go, write it back (FerretDB's `updateOne`), 200 different cards |
+| Add | insert a card |
+
+Each read is asked of 15 boards - the 3 biggest and 12 ordinary ones, as in the
+speed test - and a cell is the average of the 15 medians. Times are milliseconds
+for one call, **Total** is the sum of the six and the table is ordered by it. Every
+engine first has to give the right number of cards and the right counts for every
+board, and the writes must be there afterwards: a fast wrong answer is no answer.
+
+**SQLite is set up as FerretDB sets it**: WAL, `synchronous=NORMAL`, a 64 MiB cache
+and 256 MiB of mmap, the document as JSON and the indexes on `json_extract`
+expressions. A row with plain columns shows what SQLite could do and FerretDB does not.
+The key-value stores keep a document under `d/<id>` and an index of
+(boardId, archived) as keys, which is what a handler on them would have to build.
+No engine fsyncs per commit except where the row says so, to match SQLite's
+`NORMAL`.

+
+## What it says
+
+- **Nothing is faster where it counts.** A board's cards cost 1.4 ms at 15,000 cards
+  and 5.7-6.2 ms at 154,000 for every engine that is not slower, and nearly all of
+  it is decoding the JSON, which is the same work whatever stores it. Totals are
+  within 5% of SQLite's for Nutsdb and bbolt.
+- **The key-value stores win single reads and writes, by microseconds.** A card by
+  id takes 0.0003-0.0006 ms on bbolt, Nutsdb and BuntDB against SQLite's 0.008; an insert
+  0.001 ms on Pebble against 0.062; an edit 0.022 ms on Nutsdb against 0.072. But the
+  cheapest call through FerretDB costs about 0.2 ms in the speed test (the protocol,
+  the handler, the network) and most cost more, so an engine that took nothing at all would make one call
+  at most a few percent faster.
+- **Some are slower, and by a lot.** Pebble's LSM is 12x SQLite on fetching a big
+  board's cards (5.0 ms against 0.43), Badger 3.5x, Clover about 1,300x (it decodes every
+  document to answer anything), 90-190x in total. **bbolt with its default - an fsync on every commit
+  - takes 8-12 ms per write, 100-160x SQLite's**; without it, it is as fast as
+  SQLite and not durable the same way.
+- **The cost is in what is not there.** A key-value store has keys. FerretDB's SQLite
+  handler is about 8,500 lines because filters, sorting, `$or`, `$in`, regular
+  expressions, aggregation, indexes and statistics are SQL there. On a key-value
+  store the handler would do them in Go, and this benchmark asked only the six
+  easiest questions. Of the stores here only BuntDB and Clover have indexes on JSON
+  fields, and neither has a query language that could take SQLite's place.
+- **Loading** at 154,000 cards: Badger 0.4 s, Nutsdb 0.3 s, Pebble 2.0 s, SQLite 1.8
+  s, BuntDB 4.3 s, bbolt 14.5 s (unsorted inserts), Clover 26 s.
+- Disk: SQLite 141 MB, Pebble 67, Nutsdb 132, BuntDB 124, bbolt 274, Clover 301.

+| --- | --- |
+| goleveldb (2024-05), tiedot (2021), pudge (2021), scribble (2023), ledisdb (2023), hare, diskv, libradb | not maintained since 2021-2024, or toys; the engines that matter of their kind (LSM, B+tree) are Pebble, Badger and bbolt, tested |
+| Bitcask, pogreb, moss, LotusDB, RoseDB, Coffer, tempdb | more key-value stores of the same kind; they would also need the handler to do what SQL does |
+| gedb, [minisql](https://github.com/RichardKnop/minisql) (54 stars) | not looked at beyond their descriptions: a MongoDB-like store and a young single-file SQL database |
+| [rqlite](https://github.com/rqlite/rqlite), [redka](https://github.com/nalgeon/redka) | they are SQLite underneath, so not faster by construction |
+| [Dolt](https://github.com/dolthub/dolt), [TiDB](https://github.com/pingcap/tidb) | tested as servers in the [speed test](../) (Dolt the slowest of all, TiDB 2.3x MySQL's total); embedding their engines (go-mysql-server) would bring the same engines and far more code |
+| CockroachDB | not open source (proprietary licence) |
+| immudb | GitHub does not recognise its licence as an open-source one (`NOASSERTION`); an immutable ledger |
+| DiceDB, godis, rotom, Vasto, ledisdb | Redis-style servers, not libraries |
+| Dgraph, EliasDB, NornicDB, MemHop | graph databases |
+| InfluxDB, Prometheus, VictoriaMetrics, LinDB, lynxdb, nanotdb, unitdb | time series and logs |

+| CovenantSQL, Databunker, NoKV, piladb | blockchain, a PII vault, a metadata service, a stack |
+
+## What would be needed to know more
+
+A real answer for one engine means a handler for it: query pushdown, updates,
+indexes, statistics, 2,000-8,000 lines each. This benchmark says where it could pay:
+nowhere on reads (decoding dominates), and only on small writes, which the protocol
+hides. It does not measure what SQLite does in the engine and a key-value store
+would do in Go - sorting, `$or`, regular expressions, aggregation - where SQLite can
+only be ahead.
