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	c5bc9ed2c6	DNS Cache Fixes ... * If a MySQL connection fails or times out for a specific hostname, the corresponding DNS record will be removed from DNS Cache. This ensures that outdated DNS records are not retained. (Rest of the DNS resolution process remains unchanged) * DNS cache functionality will automatically be disabled when ProxySQL is run with the -M or --no-monitor option.	1 year ago

Rahim Kanji	8c92f9292a	A hostgroup can now be configured to have a maximum number of online servers simultaneously. Once this limit is reached, any new connections attempting to access the connection pool will be denied, and existing connections will gradually be reassigned to the available connection pool until the number of online servers is reduced to meet or fall below the specified maximum.	2 years ago

René Cannaò	7f57f20e5a	Merge pull request #4430 from sysown/v2.x-4241 ... Added metric MultiplexDisabled_ext #4241	2 years ago
René Cannaò	41cd740701	Added metric MultiplexDisabled_ext #4241 ... In the output of PROXYSQL INTERNAL SESSION and stats_mysql_processlist.extended_info , MultiplexDisabled was only returning the output of MySQL_Connection::MultiplexDisabled() . If there was a transaction, or an error, multiplexing was disabled but MultiplexDisabled() was still reporting false. Therefore it was necessary to also check server_status flag and last_errno. This commits intruduces MultiplexDisabled_ext , that reports the output of: MySQL_Connection::MultiplexDisabled() || MySQL_Connection::isActiveTransaction() This should make troubleshooting easier. Also, removed any reference to deprecated STATUS_MYSQL_CONNECTION_TRANSACTION . Closes #4241	2 years ago
