Rahim Kanji	743cd502a5	* Updated variable name from 'mysql-query_cache_with_warnings_support' to 'mysql-query_cache_handle_warnings' ... * Introduced global variable 'mysql-handle_warnings' to control warning support in ProxySQL * Included 'handling_warnings' flag in the 'mysql_hostgroup_attributes' table (hostgroup_settings). This flag holds top priority and can override the value of the global variable 'mysql_handle_warnings'.	2 years ago
Rahim Kanji	6b295477d6	Enhanced Warnings handling in ProxySQL: ... * Implemented 'SHOW WARNINGS' and 'SHOW COUNT(*) FROM WARNINGS' query handling. * When a query produces warnings, the warning count is now included in the query response. Additionally, a new variable 'mysql-query_cache_with_warnings_support' has been introduced for the query cache feature: * A value of '0' means that if a query execution produces warnings, the resultset will not be saved in the query cache. * A value of '1' indicates that if a query produces warnings, the resultset will be saved in the query cache, but the warning count in that resultset will be set to '0'. ** Note: * Warning handling is dependent on the query digest and 'mysql-query_digests' must be enabled for it to work. * Warnings saved in logfile ['mysql-log_mysql_warnings_enabled'] and the current feature can work in conjunction with each other.	2 years ago

René Cannaò	a6ff9e33ba	Initialize thr_SetParser	3 years ago
René Cannaò	37f8a50b90	Adding variable mysql-set_parser_algorithm ... Variable mysql-set_parser_algorithm defines which algorithm is used by SetParser for the parsing of SET statements. If value is 1: parse1() is used If value is 2: parse1v2() is used parse1v2() allows also the using a single SetParser per MySQL_Thread to process all SET statements. Regex is compiled only once. set_testing-240-t was also modified to test both algorithms	3 years ago

Javier Jaramago Fernández	8331858179	Remove thread variable for 'mysql-query_rules_fast_routing_algorithm' ... - Thread variable has been replaced for new variable in 'Query_Processor'. - Computation for 'mysql_query_rules_memory' is now performed by Admin during 'load_mysql_query_rules_to_runtime' instead of lazily by the MySQL_Threads.	3 years ago
Javier Jaramago Fernández	abccb39201	Add new variable 'mysql-query_rules_fast_routing_algorithm' ... - Implemented new variable 'query_rules_fast_routing_algorithm' that allows choosing between the classic per-thread hashmaps for 'query_rules_fast_routing' searches (1), and a new unique global hashmap (2). - Improved locking time on 'QueryProcessor::rwlock' during 'load_mysql_query_rules_to_runtime'. - Changed computation of 'mysql_query_rules_memory' to be lazily updated by threads themselves while building the per-threads maps. - Fixed 'ProxySQL_Admin::stats___memory_metrics' report of the memory metrics. - Improved 'PROXYSQLTEST 17' command, for being able to micro-benchmark and check 'query_rules_fast_routing_algorithm'.	3 years ago

René Cannaò	62182da20b	Merge pull request #4086 from sysown/v2.x-1486 ... Add soft TTL to Query Cache entries	3 years ago
Javier Jaramago Fernández	530353bea0	Log 'fast_forward' conns close due to 'log_unhealthy_connections' ... This is an improvement over commit '5751d71d'. Instead of avoiding to log when closing 'fast_forward' connections, now we log a dedicated message.	3 years ago
René Cannaò	51df157f3b	Rename query_cache_soft_ttl_percentage to query_cache_soft_ttl_pct	3 years ago
Javier Sánchez Parra	f5281b236b	Add soft TTL to Query Cache entries ... When Query Cache entries reach the soft ttl, the next query hit the backend and refresh the entry. While the refresh happens, other queries keeps getting the "old" Query Cache entry. Soft ttl is a percentage of the cache ttl and is defined by a global variable for all the entries. If the value is 0, soft ttl is disabled and no used.	3 years ago
