Verifying MySQL Replication Integrity with pt-table-checksum

Monday, June 17, 2013 - 16:30 to 17:00

Abstract

pt-table-checksum is a free tool which safely and efficiently verifies that data on MySQL replicas is identical to the master. Having inconsistent data on MySQL replicas is a well-known and rather common problem, yet many people who depend on MySQL replication never check for it. Moreover, inconsistent data can be an expensive problem, but the solution is free: pt-table-checksum.

Product Lead & Architect

Daniel joined Percona in July 2008 to work on Maatkit, which is now Percona Toolkit. He began creating and publishing MySQL tools at Hack MySQL in 2005, during his previous job as Unix sysadmin, because few tools existed at the time. At the 2010 MySQL Conference & Expo, Daniel was named the Community Contributor of the Year for his work on Maatkit.

Daniel holds a bachelor's degree in Philosophy (cum laude, Phi Beta Kappa) and a master's degree in French (summa cum laude), both from the University of Wyoming. He lives in Wyoming where the long winters give him ample time to program database tools, wax philosophically, and ponder French literature.
