René Cannaò	a752292b9e	Added function unshun_server_all_hostgroups() ... MySQL_HostGroups_Manager::unshun_server_all_hostgroups() scans all hostgroups looking for a specific server, and if shunned it will bring it back online	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
Javier Jaramago Fernández	b929758a87	Several improvements to 'group_replication_lag_action' ... 1. Introduced new global variable: 'monitor_groupreplication_max_transaction_behind_for_read_only', that modifies the behavior of 'group_replication_lag'. 2. Improved logic making use of 'MyHGC_find' instead of directly searching 'MyHostGroups' structure. 3. Improved 'group_replication_lag' documentation with new implementation updates. 4. Introduced changes to 'update_group_replication_set_writer' preserving writters placed in 'OFFLINE_SOFT' state.	5 years ago

René Cannaò	26790c3679	Merge pull request #3349 from sysown/v2.1.1-MonRo ... Optimizations for instances with a lot of hostgroups	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	aaddb4e568	Port of #3001 to 2.1.0 , related to #3000 ... A client connection can use a backend connection with a session variable set by a different client	6 years ago
René Cannaò	507a68db29	Variable mysql-monitor_replication_lag_count ... Renamed variable mysql-monitor_replication_lag_retries to mysql-monitor_replication_lag_count to match other variables naming convention. As it is a counter, it minimum value is changed to 1. Maximum value sets to 10. Use of thread storage variable mysql_thread___monitor_replication_lag_count instead of GloMTH->variables.monitor_replication_lag_retries to avoid dirty reads .	6 years ago
Javier Jaramago Fernández	a2727739e4	Added new variable 'mysql-monitor_replication_lag_retries' ... This new variable controls the number of retries that replication lag needs to exceed 'max_replication_lag' in order to set a server SHUNNED.	6 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

René Cannaò	703ee8ef0f	Reset connections instead of dropping them when mysql-max_stmts_per_connection is reached ... Also fixed a memory leak associate with this feature. Cleaned up a bit of code.	8 years ago
René Cannaò	18f6826ef7	Added new variable to limit the number of backend connections per second ... Variable name is `mysql-throttle_connections_per_sec_to_hostgroup` . Curently it is a global variable and limits the number of new connections per hostgroup, and not per specific node. For example, if mysql-throttle_connections_per_sec_to_hostgroup=100, no more than 100 new connections can be created on any hostgroup no matter the number of servers in that hostgroup. The default is very high (1000000) thus not changing default behaviour. Tuning this variable allows to control and throttle connections spikes to the backend servers. Added also new status variable `Server_Connections_delayed`. This is a counter of how many times Hostgroup Manager didn't return a connection because the limit was reached. It is worth to note that a single client request could make multiple requests, therefore this variable counts the number of time a new connection wasn't created and not how many requests were delayed.	9 years ago

Maxim Bublis	30dbcc21a8	Refactor header includes. ... * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	9 years ago
