Diagnosing MySQL Replication Failures

Mauricio Stekl — Thu, 23 Jun 2011 22:06:24 +0000

Replication is one of MySQL’s most widely-used features, and despite significant improvements over the years, it still fails. When this happens, it can be due to any number of factors, either internal or external to your MySQL database. No matter how it fails, it is always a problem that should be taken seriously. For those who do not have a thorough understanding of the MySQL binary log format or the slave’s two-phase replication architecture, safely restoring replication while maintaining data integrity can be a daunting task. This talk will show you how to interpret SHOW SLAVE STATUS, how to read MySQL’s binary logs, and how to recover a replication slave from many types of real-world failures. This talk will also cover situations from which it is currently impossible to recover without some data loss, and briefly show you a tool which might be able to help in some of these, mk-table-sync.

Presented by Devananda Van Der Veen and Justin Swanhart at O’Reilly MySQL Conference, April 2011, Santa Clara CA.
