Diagnosing & Fixing MySQL Replication

Replication is one of MySQL's most widely-used features, and despite significant improvements over the years, it can still fail. When this happens, it can be due to any number of factors, either internal or external to your MySQL database. 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. The first portion of this talk presents a detailed review of the replication architecture, while the main portion of the talk will show you how to recover a replication slave from some real-world failures.
