This is another tool in the same toolkit as archiver. I just saw a great blog post on it athttps://blog.arabx.com.au/?p=883. Documentation can be found athttps://mysqltoolkit.sourceforge.net/doc/mysql-checksum-filter.html. This is an invaluable tool for ensuring your replicated tables are staying in sync, something that MySQL replication does not do. Tables will drift and if you are dealing with critical data for read support, reports or backups, this will prove invaluable.
