dimgigov	0d51497f57	fix(raft): multi-stmt write gate, rich apply, delete kv convention ... - 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.	2026-07-30 21:14:46 +03:00
dimgigov	a462d21b25	docs: SQL writes through raft (C3b) done ... 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.	2026-07-30 21:07:14 +03:00
dimgigov	44060701b7	test(raft): E2E replicated writes; wire SQL path to raft node ... - 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.	2026-07-30 21:06:49 +03:00

dimgigov	2d09edd9f7	fix+refactor: soft keywords as identifiers, full test wiring, ORC crash docs ... - 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	2026-07-30 13:11:28 +03:00
dimgigov	ed5a71913c	fix: harden exception handling, break ARC cycles, sync license/client ... 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).	2026-07-23 01:07:51 +03:00
dimgigov	8db5cfe7e1	feat: harden storage, schema persistence, fair benches, fix wire crash ... 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.	2026-07-18 16:55:50 +03:00
dimgigov	aa4ab11210	feat: canonical Nim client refactor with typed rows, pool, and allographer wrapper ... - Extract wire protocol into clients/nim/src/baradb/wire.nim - Add BaraError exception hierarchy - Refactor BaraClient/SyncClient with typedRows, AsyncLock request queue, timeouts, TLS config - Add BaraPool and optional HTTP fallback - Add mock-server wire and pool unit tests - Bump baradb nimble package to 1.2.0 - Make nim-allographer depend on canonical baradb client - Use typed rows in allographer toJson - Deprecate src/barabadb/client/client.nim - Update docs/en/clients.md and clients/nim/README.md	2026-06-18 21:29:55 +03:00
dimgigov	1c42eff7ef	fix(vector): use float64 accumulators for distance functions ... 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.	2026-06-12 23:06:19 +03:00
dimgigov	ef264d7d69	feat: add unified search engine — HNSW heap-opt, segment index, boolean/phrase/ngram/facet ... New src/barabadb/search/ module with 9 components: - priority_queue.nim: BoundedHeap for O(log n) search - hnsw_opt.nim: heap-based searchLayer (2.4x faster, 92-99% recall@10) - inverted.nim: segment-based index with soft-delete and compaction - phrase.nim: positional phrase + proximity search - boolean.nim: recursive descent parser (AND/OR/NOT/ranges/wildcards) - ngram.nim: trigram index for O(1) fuzzy/prefix/wildcard - stemmer.nim: Porter2 stemmers (EN/BG/DE/FR/RU) - facet.nim: faceted search with filter pushdown - engine.nim: UnifiedSearchEngine combining all search types Performance (dim=128, efConstruction=200): N=1K: 0.30ms search, 99.6% recall@10 N=10K: 1.09ms search, 92.6% recall@10 N=50K: 2.26ms search, 75.5% recall@10 Includes search benchmarks (benchmarks/search_bench.nim), updated docs (en/bg fts.md, en/bg search.md), and crossmodal engine integration.	2026-05-30 13:42:08 +03:00
dimgigov	965ed2f675	perf: optimize FTS and HNSW engines + real PostgreSQL benchmarks ... FTS Engine (src/barabadb/fts/engine.nim): - Fix bm25Score doing O(n) linear scan per document - Cache IDF per token instead of recomputing for each doc - Use entry.termFreq directly instead of searching postings again - Result: FTS search +438% (249 -> 1360 queries/s) HNSW Vector Engine (src/barabadb/vector/engine.nim): - Optimize distance functions with float32 + 4x loop unrolling - Rewrite searchLayer: swap+pop instead of O(n) del, track worst-nearest instead of sorting nearest on every iteration - Result: HNSW insert +117% (245 -> 543 ops/s), search 2.2x faster Benchmarks: - Add real PostgreSQL comparison script (benchmarks/pg_bench.py) - Add report generator (benchmarks/generate_report.py) - Fix compare.nim cpuTime() bug (was dividing by 1M incorrectly) - Add nimble tasks: bench_pg, bench_report Docs: - Update README.md and docs/en/performance.md with real measured numbers - Add benchmarks/REAL_COMPARISON.md Version bump: 1.1.7 -> 1.1.8	2026-05-29 17:11:22 +03:00
