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

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

If variable mysql-monitor_replication_lag_group_by_host=true: Monitor will perform 1 replication lag check per server. This variable need to be set only in setups in which the same server is configured in many hostgroups, thus reducing the number of checks	4 years ago

René Cannaò	2ba9c401f1	Bug fixes in the new implementation of tracking mysql variables ... Better parsing of SET SQL_LOG_BIN . SQL_LOG_BIN is now managed by the same functions that handle boolean variables instead of the now deprecated MySQL_Session::handler_WCD_SS_MCQ_qpo_Parse_SQL_LOG_BIN() For naming convention, enum value SQL_LOG_BIN was renamed to SQL_SQL_LOG_BIN In MySQL_Thread we also deprecated match_regexes[0] , previously used to parse `set sql_log_bin`. Functions Variable::fill_server_internal_session() and Variable::fill_client_internal_session() seems to handle sql_log_bin as a special value. This exception was removed. Fixed a bug in MySQL_Session::generate_proxysql_internal_session_json() where when backend variables needed to be generated, fill_client_internal_session() was incorrectly called instead of fill_server_internal_session() , leading to incorrect values reported by `PROXYSQL INTERNAL SESSION`	4 years ago

René Cannaò	c4fce91fc5	Change default value of mysql-session_idle_ms from 1000 to 1 ... Not only the default value is change from 1000 to 1 , but it also perform an upgrade from earlier release. If during bootstrap a value of 1000 is found, it is automatically changed to 1 and a warning is generated. This release also prevents the value 1000 to be a valid one during bootstrap. This means that it is still possible to set the value to 1000 and to have a running proxysql instance with value 1000 , but during bootstrap it will be switched to 1. If you really want to set mysql-session_idle_ms close to 1000 , it is recommended to set it to a closer value like 999 or 1001	5 years ago
