pt-table-sync feels as though it could be more efficiently used if provided with --where params based upon the results from pt-table-checksum. It doesn’t seem to do so when running --sync-to-master, though. It feels inefficient re-process an entire large table.
I can see which tables need attention from the CRC and CNT values in checksums. Does anyone know how to compose a where statement based upon the content in the checksums table, or perhaps have a different workflow suggestion?
