René Cannaò	3520dbbacc	Remove all references to PS handling before 1.4 Handling of prepared statements changed a lot in 1.4 , as a lot of code was rewritten. Old code was still present, and was possible to toggle it on and off based on PROXYSQL_STMT_V14 . Because only the new code is maintained, all references to old code are now removed, including PROXYSQL_STMT_V14	9 years ago

René Cannaò	7eccd347e3	Add support for Percona Heartbeat #1248 This commits adds a new variable: mysql-monitor_replication_lag_use_percona_heartbeat This variable defines the percona heartbeat table used to check replication lag. If set, replication lag is checked against the defined table, otherwise `SHOW SLAVE STATUS` is used. To be set, the value should match the following regex: ``` `?([a-z\d_]+)`?\.`?([a-z\d_]+)`? ```	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	a22eb8b395	No connection from pool for fast_forward #1157 If a user is configured with fast_forward, no connection should be taken from the connection pool. Yet the Hostgroup Manager should know about such connection.	9 years ago
René Cannaò	e3c4cb9964	A lot of changes all related to Cluster In `MySQL_Cluster` class added functions to sync with remote node, like: - `pull_mysql_query_rules_from_peer()` - `pull_mysql_servers_from_peer()` - `pull_mysql_users_from_peer()` - `pull_proxysql_servers_from_peer()` Added 8 new global variables in Admin. 4 variables determine after how many different checks the remote configuration will be synced: - cluster_mysql_query_rules_diffs_before_sync - cluster_mysql_servers_diffs_before_sync - cluster_mysql_users_diffs_before_sync - cluster_proxysql_servers_diffs_before_sync 4 variables determine if after a remote sync the changes need to be written to disk: - cluster_mysql_query_rules_save_to_disk - cluster_mysql_servers_save_to_disk - cluster_mysql_users_save_to_disk - cluster_proxysql_servers_save_to_disk Table `proxysql_servers` is now automatically loaded from disk to memory and into runtime at startup. Added new Admin's command `LOAD PROXYSQL SERVERS FROM CONFIG` to load `proxysql_servers` from config file to memory (not runtime). Internal structures with credentials in MySQL_Authentication moved from `unsorted_map` to `map` : this to ensure the right order when generating the checksum. Config file supports both `address` and `hostname` for `mysql_servers` and `proxysql_servers` , #1091 `ProxySQL_Admin::load_proxysql_servers_to_runtime()` now has a lock or no lock option, to avoid deadlock For now, Cluster module is quite verbose.	9 years ago
René Cannaò	2a76f95e31	Further enhancement on Cluster Extended class ProxySQL_Checksum_Value() in ProxySQL_Cluster module to support further metrics Implemeted `SELECT GLOBAL_CHECKSUM()` and relative tracking of global checksums Added variable `admin-cluster_check_status_frequency` to check peer's global status at regular intervals	9 years ago
René Cannaò	ee8110a515	Enhancement on Cluster solution This commit introduces: 2 new tables: * `runtime_checksums_values` : stores checksums of configurations in runtime. For now for `mysql_query_rules`, `mysql_servers` and `mysql_users` * `stats_proxysql_servers_checksums` : when clustering is enabled, it collects all metrics from `runtime_checksums_values` from all its peers 3 new global variables that defines it checksum needs to be generated during `LOAD ... TO RUNTIME` * `admin-checksum_mysql_query_rules` * `admin-checksum_mysql_servers` * `admin-checksum_mysql_users` ProxySQL Cluster connections now have timeouts: * 1 second timeout for CONNECT and WRITE * 60 seconds timeout for READ (useful for long poll)	9 years ago

René Cannaò	2403b177ef	More support for Group Replication Enforced max_writers Enforced writer_is_also_reader Increased the number of entries in mysql_server_group_replication_log to 100 per node Lowered the minimum value for mysql-monitor_groupreplication_healthcheck_interval to 50ms Lowered the minimum value for mysql-monitor_groupreplication_healthcheck_timeout to 50ms	9 years ago
René Cannaò	752e3fd61e	Further improvement on forwarding #927 Introduced a timeout in HGCU_thread_run() Fixed a logical bug in MySQL_Protocol::process_pkt_COM_CHANGE_USER() that was causing to not authenticate user The absence of the timeout and the logicl bug was causing a lot of connections to be dropped and not really reused. But as now the connections are reused, they may present further bugs	9 years ago

René Cannaò	8768acf5a5	Third commit for GR support	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	53d24f4e53	Speed up LOAD/SAVE mysql_servers #829 A further optimization in `MySQL_HostGroups_Manager::generate_mysql_servers_table()` makes `LOAD MYSQL SERVERS TO RUNTIME` around 35 times faster than original implementation. `SAVE MYSQL SERVERS TO MEMORY` is now over 10 times faster than the original implementation.	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
