Rene Cannao	fb66af7c1b	feat: Expose MCP catalog database in ProxySQL Admin interface The MCP catalog database is now accessible as the 'mcp_catalog' schema from the ProxySQL Admin interface, enabling direct SQL queries against discovered schemas and LLM memories.	3 months ago
Rene Cannao	a816a756d4	feat: Add MCP query tool usage counters to stats schema Add stats_mcp_query_tools_counters and stats_mcp_query_tools_counters_reset tables to track MCP query tool usage statistics. - Added get_tool_usage_stats_resultset() method to Query_Tool_Handler - Defined table schemas in ProxySQL_Admin_Tables_Definitions.h - Registered tables in Admin_Bootstrap.cpp - Added pattern matching in ProxySQL_Admin.cpp - Added stats___mcp_query_tools_counters() in ProxySQL_Admin_Stats.cpp - Fixed friend declaration for track_tool_invocation() - Fixed Discovery_Schema.cpp log_llm_search() to use prepare_v2/finalize	3 months ago
Rene Cannao	ef07831780	Add MCP module to admin bootstrap and SHOW MCP VARIABLES command The MCP module was not being loaded because: 1. The admin bootstrap process was not calling flush_mcp_variables___database_to_runtime - Added the call after flush_sqliteserver_variables___database_to_runtime 2. There was no SHOW MCP VARIABLES command handler - Added the handler in Admin_Handler.cpp, following the same pattern as SHOW MYSQL VARIABLES and SHOW PGSQL VARIABLES Now after this change: - MCP variables (mcp-enabled, mcp-port, mcp-mysql_hosts, etc.) will be automatically inserted into global_variables table during ProxySQL startup - Users can run "SHOW MCP VARIABLES" to list all MCP configuration variables - The configure_mcp.sh script will work correctly Note: Requires rebuilding ProxySQL for changes to take effect.	3 months ago
Rene Cannao	01d654692d	Integrate sqlite-rembed for text embedding generation Add support for sqlite-rembed Rust SQLite extension to enable text embedding generation from remote AI APIs (OpenAI, Nomic, Ollama, Cohere, etc.) within ProxySQL's SQLite3 Server. Changes: 1. Build system integration for Rust static library compilation - Rust toolchain detection in deps/Makefile - Static library target: sqlite3/libsqlite_rembed.a - Linking integration in lib/Makefile and src/Makefile 2. Extension auto-registration in Admin_Bootstrap.cpp - Declare sqlite3_rembed_init() extern C function - Register via sqlite3_auto_extension() after sqlite-vec 3. Documentation updates - doc/sqlite-rembed-integration.md: comprehensive integration guide - doc/SQLite3-Server.md: usage examples and provider list 4. Source code inclusion - deps/sqlite3/sqlite-rembed-source/: upstream sqlite-rembed v0.0.1-alpha.9 The integration follows the same pattern as sqlite-vec (static linking with auto-registration). Provides rembed() function and temp.rembed_clients virtual table for embedding generation. Build requires Rust toolchain (cargo, rustc) and clang/libclang-dev.	4 months ago

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

Rahim Kanji	720441af20	Refactored and Optimized Query Cache with PgSQL Support * Added Query Cache Support for PgSQL: * Introduced new variables for PgSQL Query Cache management: * pgsql-query_cache_size_MB * pgsql-query_cache_soft_ttl_pct * pgsql-query_cache_stores_empty_result * pgsql-query_cache_handle_warnings (not yet utilized) * Overwriting Transaction Status: * Sending current transaction state to the client when a result is returned from the query cache. * This currently does not differentiate between normal and error transaction states—both are treated as active transaction states. * Cache Lifetime Management: Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries, ensuring proper memory deallocation and reducing complexity. * Unified Purging Logic: Refactored the query cache purging logic to use a single thread for both MySQL and PgSQL cache entries. * Code Cleanup: Removed unnecessary methods and data members to streamline the codebase and improve maintainability. * Performance Optimization: Improved memory management, reducing memory footprint and enhancing performance.	2 years ago
