REPLICATION CLIENT Privilege
Grants ability to SHOW MASTER STATUS, SHOW SLAVE STATUS, SHOW BINARY LOGS. In ES10.5, is an alias for BINLOG MONITOR and the capabilities have changed. BINLOG MONITOR grants ability to SHOW MASTER STATUS, SHOW BINARY LOGS, SHOW BINLOG EVENTS, and SHOW BINLOG STATUS.
Starting in ES10.5 and CS10.5 BINLOG MONITOR is a synonym for REPLICATION CLIENT but the capabilities have changed.
If a user upgrades from ES10.4 or earlier to ES10.5.8-5 or later, any users with REPLICATION CLIENT and REPLICATION SLAVE privileges will automatically be granted the REPLICA MONITOR privilege. This privilege upgrade happens upon server startup, so
mysql_upgradeis not required.
The upgrade behavior does not apply to minor release upgrades that upgrade from ES10.5.6-4 or earlier ES10.5.x release to ES10.5.8-5 or later.
