René Cannaò	f7754a5e00	HostGroups lookup using unordered_map ... HostGroups are stored in an array of pointers. This commit allows the lookup using an unordered_map if the number of Hostgroups is greater than 100. For less number of hostgroups, a sequential scan seems more efficient. This also introduce a test for micro benchmark.	5 years ago
René Cannaò	532a0397f7	Faster MySQL_HostGroups_Manager::read_only_action ... This commit rewrites MySQL_HostGroups_Manager::read_only_action() in way to reduce the calls to SQLite. It relies on two new std::set() : - read_only_set1: if the server is already in a writer hostgroup - read_only_set2: a cache to track the first time that a server has RO=0 Added also an index on MySQL_HostGroups_Manager, ON mysql_servers (hostname,port)	5 years ago

René Cannaò	33d8db02a6	Change the mapping logic for SESSION_TRACK_GTIDS ... Changing the mapping logic in SESSION_TRACK_GTIDS in frontend and backend connections. Up to now, frontend and backend `SESSION_TRACK_GTIDSs match. This is now changed: * backend connections are by default set to `mysql-default_session_track_gtids` * if `mysql-default_session_track_gtids=OFF` (the default) , `session_track_gtids` is not changed on backend * if the client asks for `session_track_gtids=OFF` , proxysql ignores it (it just acknowledge it) * if the client asks for `session_track_gtids=OWN_GTID` , proxysql will apply it * if the client asks for `session_track_gtids=ALL_GTIDS` , proxysql will switch to OWN_GTID and generate a warning * if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities This commit also deprecates function `MySQL_Session::handler_again___verify_backend__generic_variable()` ProxySQL is now also able to know when proxysql binlog reader is perhaps in use tracking all gtid_port in mysql_servers. This feature in future will be used to deprecate `mysql-default_session_track_gtids`	6 years ago
