Keyword Description
SQL statement for accessing the latest global
fetch_last_gtid
transaction identifier. The SQL statement
is run if the plugin needs to know the most
recent global transaction identifier. This can
be the case, for example, when checking
MySQL Replication slave status. Also used
with mysqlnd_ms_get_last_gtid.
SQL statement for checking if a replica has

that can deliver session consistency. The
setting limits the time spend for polling the
