Fortunately Maatkit has a neat solution with 2 nice scripts: mk-table-checksum, which is a tool to detect inconsistencies between a master and its slaves and mk-table-sync, which can correct automatically these problems detected with mk-table-checksum.

This session will show you first how to use both tools depending on your replication setup (master-slaves or master-master) and then how to get the most from the multiple options that are available.
