ProxySQL needs to consider the new mysql source/replica terminology commands wherever applicable. MySQL 8.4+ no longer recognize the old master/slave terminology commands.
AFAICS the below three stats in stats_mysql_commands_counters table needs to be updated to consider the new terminology commands:
CHANGE_MASTER (shall consider CHANGE REPLICATION SOURCE)
RESET_MASTER (shall consider RESET BINARY LOGS AND GTIDS)
RESET_SLAVE (shall consider RESET REPLICA)
ProxySQL version : 2.7.1
OS version: centos 9
Steps to reproduce:
Setup proxysql with at least one backend mysql 8.4+ server correctly configured.
Configure the mysql user in proxysql, ensure that the user with necessary privileges exists on mysql 8.4+ server.
Open proxysql connection via the user configured.
Execute CHANGE MASTER command with right syntax as per mysql 8.0, the query errors out as syntax ERROR but the stats_mysql_commands_counters table will increase the count for CHANGE_MASTER.
Execute CHANGE REPLICATION SOURCE command with right syntax, the query executes successfully on server but no effect in CHANGE_MASTER counter.
Same behavior for RESET_MASTER and RESET_SLAVE
Fix:
Rename CHANGE_MASTER, RESET_MASTER and RESET_SLAVE to CHANGE_REPLICATION_SOURCE, RESET_BINARY_LOGS_AND_GTIDS and RESET_REPLICA respectively and when server is 8.4+ then consider only the new terminology commands as old terminology commands are invalid and when the version is lower then 8.4 then consider both the new and old terminology commands.
