Rene Cannao	d55947b49f	Add comprehensive documentation for sqlite-vec integration ... This commit adds extensive documentation for the sqlite-vec vector search extension integration in ProxySQL, including: ## README Documentation ### deps/sqlite3/README.md - Overview of sqlite-vec and its vector search capabilities - Integration method using static linking - Directory structure explanation - Compilation flags and build process details - Usage examples for all ProxySQL databases - Benefits and verification instructions ### deps/sqlite3/sqlite-vec-source/README.md - Complete sqlite-vec documentation - Source files explanation - Integration specifics for ProxySQL - Licensing information - Standalone building instructions - Performance considerations ## Doxygen Code Documentation ### lib/Admin_Bootstrap.cpp - Added comprehensive doxygen comments for sqlite-vec integration - Documented sqlite3_vec_init function declaration - Added section documentation for SQLite database initialization - Detailed documentation for each database instance: * Admin: Configuration analytics and vector operations * Stats: Performance metrics and similarity analysis * Config: Configuration optimization with vectors * Monitor: Anomaly detection and pattern recognition * Stats Disk: Historical trend analysis - Included usage examples and cross-references - Explained auto-extension mechanism and integration benefits The documentation provides developers with a complete reference for understanding, using, and maintaining the sqlite-vec integration in ProxySQL's SQLite databases. Technical Details: - Static linking implementation - Virtual table mechanism - JSON vector format support - Auto-extension registration - Multi-database integration - Performance optimizations	4 months ago
Rene Cannao	fbd0d9732b	Add sqlite-vec static extension for vector search in ProxySQL ... This commit integrates sqlite-vec (https://github.com/asg017/sqlite-vec) as a statically linked extension, enabling vector search capabilities in all ProxySQL SQLite databases (admin, stats, config, monitor). Changes: 1. Added sqlite-vec source files to deps/sqlite3/sqlite-vec-source/ - sqlite-vec.c: main extension source - sqlite-vec.h: header for static linking - sqlite-vec.h.tmpl: template header 2. Modified deps/Makefile: - Added target sqlite3/sqlite3/vec.o that copies sources and compiles with flags -DSQLITE_CORE -DSQLITE_VEC_STATIC - Made sqlite3 target depend on vec.o 3. Modified lib/Makefile: - Added $(SQLITE3_LDIR)/vec.o to libproxysql.a prerequisites - Included vec.o in the static library archive 4. Modified lib/Admin_Bootstrap.cpp: - Added extern "C" declaration for sqlite3_vec_init - Enabled load extension support for all databases: - admindb, statsdb, configdb, monitordb, statsdb_disk - Registered sqlite3_vec_init as auto-extension at database open (replacing commented sqlite3_json_init) 5. Updated top-level Makefile: - Made GIT_VERSION fallback to git describe --always when tags missing Result: - Vector search functions (vec0 virtual tables, vector operations) are available in all ProxySQL SQLite databases without runtime dependencies - No separate shared library required; fully embedded in proxysql binary - Extension automatically loaded at database initialization	4 months ago
