Verifying Replication Integrity with Percona Toolkit
Percona Toolkit 2.0 has a newly upgraded tool for verifying replication integrity, pt-table-checksum. This unique tool verifies that your replicas have exactly the same logical dataset as their masters. No other tool offers this capability, yet it's vitally important to check that replication isn't causing data drift, and correct any problems that might be uncovered. In this webinar we'll explain why replicas can diverge from the master, discuss how pt-table-checksum works, and explore the new features in pt-table-checksum that make it work seamlessly out of the box, even on extremely large and heavily loaded servers.
