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	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
