- evalExpr accepts optional ExecutionContext for FTS index lookup
- CREATE INDEX ... USING FTS builds InvertedIndex from existing data
- @@ uses BM25 scoring when FTS index exists, falls back to term match
- INSERT/UPDATE/DELETE auto-maintain FTS indexes
- 283 tests, 0 failures
- Recursive CTE execution (WITH RECURSIVE + UNION ALL, work-table loop)
- UNION / INTERSECT / EXCEPT parser + executor (nkSetOp)
- DROP INDEX parser + executor
- VIEW DDL persistence via AST-to-SQL serializer
- JSON path operators -> and ->> (lexer, parser, IR, executor)
- FTS SQL wiring WHERE col @@ 'query' (case-insensitive term match)
- Multi-column index range scans (prefix equality + range on last col)
- Covering index optimization (skip LSM read when index covers SELECT)
- SCRAM-SHA-256 authentication (password-based validation)
- 279 tests, 0 failures
- Add fkJson to wire protocol with serialization/deserialization
- Validate JSON/JSONB on INSERT/UPDATE via std/json
- Send real column type metadata in wire protocol responses
- Update all 4 clients (Nim, Python, JS, Rust) for JSON and columnTypes
- Implement multi-column index parser (CREATE INDEX idx ON t(a, b))
- Add ciColumns to AST nkCreateIndex
- Build composite index keys as table.col1.col2 with val1|val2
- Support multi-column exact match in SELECT for AND chains
- Implement non-recursive CTE execution via ctx.cteTables materialization
- Add tkRecursive token and parse WITH RECURSIVE
- Fix test isolation: use temp dirs for JOIN, migration, and RLS tests
- All tests passing (0 failures)
- Fixed parseApplyMigration to use p.expect(tkApply) instead of p.expect(tkIdent)
- Added std/tables import to server.nim for Row table operations
- All 216 tests pass + 15/15 integration tests pass
Executor:
- FOREIGN KEY enforcement: checks referenced row exists on INSERT
- Type enforcement: INTEGER, FLOAT, BOOLEAN, TIMESTAMP validated
- GROUP BY execution: actual row grouping with count(*) aggregation
- WebSocket broadcast: onChange callback wired into INSERT/UPDATE/DELETE
- CREATE INDEX handler: creates B-Tree index + populates from existing data
- ALTER TABLE ADD COLUMN: actually adds column to table definition
- LIKE evaluation with regex pattern matching
- FK metadata stored in ColumnDef (fkTable, fkColumn)
Parser:
- CREATE INDEX / CREATE UNIQUE INDEX parser added
- ALTER TABLE now parses ADD COLUMN with type
HTTP Server:
- Rate limiter wired (token bucket per client IP)
- CORS headers on all responses (Allow-Origin: *, OPTIONS preflight)
- 429 Too Many Requests when rate limit exceeded
All 216 tests pass
