René Cannaò	efb716b048	Disable monitoring of servers not responding to ping ... This commit also prevents shunned nodes to come back online if they are missing pings. Related to #1416 Because it reduces the number of checks, it may also be relevant to #1417	8 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.	9 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

René Cannaò	a6c53d0d12	Revert "Refactor header includes."	10 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.	10 years ago

René Cannaò	ba7e37091b	Speed up LOAD MYSQL SERVERS TO RUNTIME #829 ... This commit is able to speed up LOAD MYSQL SERVERS TO RUNTIME up to 10x for very large mysql_servers table with tens of thousands of servers. Main improvements: * removed 1 unnecessary call to `generate_mysql_servers_table()` * replaced 1 call to `generate_mysql_servers_table()` with UPDATE statements when necessary * implemented new function `servers_add()` that replaces `server_add()` to perform bulk operation * replaced calls to `sqlite3_exec()` with proper parameters bindings * use of multirows INSERT statements (32 rows at the time) Miror improvements: * added new variable mysql-hostgroup_manager_verbose , 1 by default for backward compatibility and debugging * in not debug mode, access to HGM db has no shared cache * in not debug mode, tables in HGM have checks disabled Further note: * Once issue #797 is completed, `mysql_servers` in MyHGM can be simplified further	10 years ago
René Cannaò	86718882e0	Added 6 new status variables , #818 and #821 ... Added status variables: * Com_backend_change_user * Com_backend_init_db * Com_backend_set_names * Com_frontend_init_db * Com_frontend_set_names * Com_frontend_use_db	10 years ago

René Cannaò	8ce083fb20	Testing pthread mutex for MHM #644 ... If MHM_PTHREAD_MUTEX is defined MySQL_HostGroups_Manager.h , MySQL_HostGroups_Manager() is compiled using pthread mutex instead od spin loop. As a lot of computation is protected by mutex, maybe it is better not to use spin loop.	10 years ago
