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 Sánchez Parra	1644c9a870	Add a second group of auxiliary maps ... This way, we can merge previous maps without locking the mutex. We move locking the mutex for merging the second group of auxiliary maps. This second merge it is faster than the previous merge, because the second group of auxiliary maps is not going to grow large.	3 years ago

Javier Sánchez Parra	263d645bad	Add auxiliary maps in get_query_digests() to improve performance ... Otherwise, all queries processed by ProxySQL have to wait for get_query_digest() to finish reading the maps. With this patch, ProxySQL stores query digests in the auxiliary maps while the main maps are being used by get_query_digests(). Once get_query_digests() finish reading the main maps, it merge the auxiliary maps in to the main maps and clear the content of the auxiliary maps.	3 years ago

René Cannaò	5e68075edf	Cluster: Speed up processing of MySQL Query Rules ... Multiple changes: - Query_Processor stored the resultset of query rules loaded to runtime (previously this was only for query rules fast routing) - Admin returns the stored resultset (query rules and fast routing) when queries by Cluster - In khash replaced the hashing function from the built-in __ac_X31_hash_string to CityHash32 - When Cluster is used, it calls load_mysql_query_rules_to_runtime() passing the resultsets retrieved by the remote peer - Increased SQLite cache_size to ~50MB: this seems to be a very small optimization and probably it will be reverted - pull_mysql_query_rules_from_peer() uses transactions to write to mysql_query_rules_fast_routing - (important change) pull_mysql_query_rules_from_peer() verifies the checksum of MySQL Query ules before loading them to runtime	4 years ago

René Cannaò	7b021e027a	Do not cache routing metadata for COM_STMT_EXECUTE ... From 1.3.0 till 2.0.x , when COM_STMT_PREPARE is executed and Query Processor is executed, metadata are stored in MySQL_STMT_Global_info(). These metadata include routing information. Is a prepared statement is prepared on a specific hostgroup, it will always be executed on the same hostgroup. This causes negative consequences, like the one reported in issue #2691 . This commit: * remove hostgroup_id from MySQL_STMT_Global_info() and other metadata * Query Processor is called also during COM_STMT_EXECUTE * removes hostgroup from table stats_mysql_prepared_statements_info * Query Processor do not perform any query rewrite ruding COM_STMT_EXECUTE	6 years ago
