Rahim Kanji	06e496b7c3	Added tracking of parameters: ... * client_encoding/names * datestyle * timezone/time zone * standard_conforming_strings	1 year 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.	1 year ago

Rahim Kanji	e723082a1b	Refactored Query Processor Architecture ... - Introduced separate query processors for MySQL and PostgreSQL. - Removed unnecessary GTID logic from `PgSQL_Session`. - Added a command counter for PostgreSQL queries. - Refactored `Query_Processor` to serve as a base class containing core functionalities applicable to both MySQL and PostgreSQL. Changes: - Removed GTID-related code from `PgSQL_Logger` and `PgSQL_Session`: - bool with_gtid; - char gtid_buf[128]; - int gtid_hid; - Added new PostgreSQL-specific tables: - `pgsql_query_rules`, `pgsql_firewall_whitelist_rules`, `pgsql_query_rules_fast_routing` - `runtime_pgsql_query_rules`, `runtime_pgsql_firewall_whitelist_rules`, `runtime_pgsql_query_rules_fast_routing` - Added PostgreSQL-related variables: pgsql_thread___commands_stats pgsql_thread___query_digests pgsql_thread___query_digests_lowercase pgsql_thread___query_digests_no_digits pgsql_thread___query_digests_replace_null pgsql_thread___query_digests_normalize_digest_text pgsql_thread___query_digests_track_hostname pgsql_thread___query_digests_keep_comment pgsql_thread___query_digests_max_digest_length pgsql_thread___query_digests_max_query_length pgsql_thread___query_digests_grouping_limit pgsql_thread___query_digests_groups_grouping_limit pgsql_thread___enable_load_data_local_infile pgsql_thread___auditlog_filename pgsql_thread___auditlog_filesize pgsql_thread___eventslog_filename pgsql_thread___eventslog_filesize pgsql_thread___eventslog_default_log pgsql_thread___eventslog_format pgsql_thread___firewall_whitelist_errormsg pgsql_thread___firewall_whitelist_enabled pgsql_thread___query_processor_iterations pgsql_thread___query_processor_regex	1 year ago
