I think there used to be a mysqldbcompare tool (old web pages talk about it), but that seems to be gone. I don't see this feature in the MySQL Workbench. Is there something new which replaced it?
Percona has a pt-table-checksum tool which is very sophisticated, but unfortunately, it requires statement replication (which it can set itself at the session level), but won't work with replicates of replicates (and super priv on the 1st replicate)
Thanks in advance
