Rahim Kanji c0f99c0e15 Refactor: Improved Prepared-Statement Cache Design (Lock-Free Hot Path) #5211 ... Concurrency and Memory Management * Lock-Free Ref Counting: Replaced global mutex-protected integer reference counts with `std::atomic<uint32_t>` within `PgSQL_STMT_Global_info`, eliminating lock contention during statement referencing. * Modern Ownership: Adopted std::shared_ptr<const PgSQL_STMT_Global_info> for global and local storage, providing automatic, thread-safe memory and lifecycle management. * Memory Optimization: Removed redundant auxiliary maps `global_id_to_stmt_names` and `map_stmt_id_to_info` from local and global statement managers respectively, reducing overall memory overhead. * Optimized Purging: Statement removal logic was simplified for efficiently identifying and cleaning up unused statements. Hot Path Performance (`BIND`, `DESCRIBE`, `EXECUTE`) * Bypassed Global Lookups: Local session maps now store the `shared_ptr` directly, removing the need to acquire the global lock and search the global map during hot path operations. * Direct Refcount Manipulation: Refcount modification functions now operate directly on the passed statement object, eliminating the overhead of searching the global map to find the object pointer based on statement id. Safety and Protocol Logic (`PARSE`) * Efficient Statement Reuse: Implemented a **local fast path** check for the unnamed statement (`""`), allowing immediate reuse of an identical query (same hash) upon re-parse, which bypasses global processing and locks. Cleanup * Cleaned up and class rename `PgSQL_STMT_Manager_v14` -> `PgSQL_STMT_Manager`.		3 months ago
