- Add raft-cluster-status overview (C3a/C3b/post-C3b shipped on main)
- Mark C3a/C3b design+plans done; refresh operator docs en/bg
- CHANGELOG 1.2.0 Raft section; README cluster example and status line
- monitoring.md health/metrics match real HTTP port+440 and raft series
- lastSnapshotIndex/Term bound the compacted prefix; lastLogIndex/Term
and AppendEntries prevLog checks respect the snapshot base
- compactLog drops entries only through min(matchIndex, lastApplied) on
the leader so lagging peers can still catch up via AppendEntries
- Persist snapshot fields in raft_state.bin; BARADB_RAFT_LOG_MAX_ENTRIES
- Fix commit-index scan to use findLogEntryByIndex (works after compact)
- BARADB_RAFT_CLIENT_PEERS maps node id → SQL client host:port
- Followers proxy DML/DDL to the known leader over the wire protocol
(falls back to "not leader" when the map is missing)
- E2E: follower CREATE/INSERT succeed via forward; docs updated
- isRaftDdl + leader-only gate for CREATE/DROP/ALTER (not DATABASE)
- appendDdlToRaft ships original SQL; applyCommand re-executes via
applyReplicatedDdl (idempotent on leader double-apply)
- Mixed DDL+DML batches use the DDL path so order is preserved
- Fix secondary-index point lookup to use entry.lsmKey (not filter col)
- E2E: CREATE only on leader, schema + index SELECT on follower
- applyReplicatedPut/Delete keep in-memory graphs in sync with node/edge
table rows (idempotent edges via addEdgeWithIdIfAbsent).
- When Raft is enabled, DML is refused on any database other than
'default' (the only DB the state machine is wired to).
- Docs updated (en/bg); unit test for graph apply.
- Reject follower writes if any statement in the batch is DML/COMMIT
(not only stmts[0]).
- COMMIT always emits empty-valued kvPairs for isDelete entries.
- applyCommand updates LSM plus secondary B-tree/FTS/HNSW indexes
(applyReplicatedPut/Delete) so follower index scans see replicated rows.
- Tests: not-leader append, commit timeout, index apply unit, E2E
index-backed SELECT on follower.
Mark the C3b design done; document leader-only DML, env vars, and default-DB
apply limits in en/bg distributed docs; refresh the README raft status line.
- Fix runTcpServer to run the already-wired Server (raftNode was assigned
on a different instance that never accepted clients).
- Cap raft peer connect at 200ms and fan out heartbeats in parallel so a
dead peer cannot stall AppendEntries to the live majority.
- Add raft_writes_e2e_test: 3-node write replication, follower rejection,
and post-failover writes; wire into nimble test + gitignore.
- parser: clause keywords (header, format, status, user, csv, ...) now work
as identifiers everywhere; IMPORT/EXPORT accept FORMAT csv/HEADER true
- nimble test + CI run all 13 test suites (650 checks green)
- ExecutionContext.registry is now {.cursor.} (breaks registry<->ctx cycle)
- ORC crash reproduced and bisected (tests/orc_repro.py); ARC stays the MM
Replace bare except: with CatchableError across storage, query, Raft,
backup, and protocol code so Defects are not swallowed. Break uncollectable
ARC cycles in server shard/gossip callbacks via Server-owned refs and
cursor locals. Align package license with LICENSE (BSD-3-Clause), sync
README version, and point test_all at the canonical clients/nim baradb
client (parseConnectionString + aliases).
Core storage: hash MemTable, WAL group commit, L0 compaction rebuild,
reader-writer lock, and a global StorageGate so HTTP workers and TCP
share the LSM safely under multi-thread access.
Schema: durable CREATE/ALTER/DROP under _schema:tables:* with full LSM
restore on open. Executor types/values/schema split into query/exec/.
Wire protocol: switch default MM to ARC — ORC cycle collector segfaulted
after ~20 async INSERTs. Fair multi-tier benchmarks (SQLite/HTTP/wire/PG)
and honesty docs for mixed-tier comparisons.
Vector distance functions (cosine, euclidean, dot, manhattan) returned
float64 but accumulated sums in float32, causing precision loss in SQL
results (e.g. sqrt(2) truncated to float32). Use float64 accumulators
and casts throughout.
docs(bugs): mark BUG-023 and BUG-024 as fixed
The code already cleans up pendingAcks and passes oldAssignments from
rebalance to migrateData; update BUGS.md to match the implementation.
