René Cannaò	38c5a76d0e	Use Aurora writer for reads if max_lag_ms isn't specified ... This solves the issue described in issue #3522 It is a side effect of a mistake in commit 5336e72f1c	5 years ago
René Cannaò	dd71fcd81f	Shun "soft" and "hard" in group replication lag ... When shunning a node due to replication lag in a group replication cluster, we first shun the node as MYSQL_SERVER_STATUS_SHUNNED , then we shun it as MYSQL_SERVER_STATUS_SHUNNED_REPLICATION_LAG . In this way we prevent (for a short time) to kill connections on that backend. This backing off from that server can give the server enough time to sync up. See discussion in comments in https://github.com/sysown/proxysql/pull/3533	5 years ago

René Cannaò	eac6e75dad	Adding a simulator for read_only test ... This commit introduces a first simulator for read_only monitoring ProxySQL itself will simulate hundreds of backends across hundreds of hostgroups, all configured in hundreds of clusters, and return read_only values for each of the simulated backend. The read_only value can be configured in table READONLY_STATUS available in the SQLite3Server module. If a backend isn't configured in table READONLY_STATUS , its default read_only value is 1. It is possible to simulate a lot of simultaneous failover running queries like the following: UPDATE READONLY_STATUS SET read_only=1; CREATE TABLE t1 AS SELECT hostname FROM READONLY_STATUS ORDER BY RANDOM() LIMIT 50; UPDATE READONLY_STATUS SET read_only=0 WHERE hostname IN (SELECT hostname FROM t1); DROP TABLE t1;	5 years ago

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
