Global Transaction ID at Facebook
Replication and High Availability Strategies
4 April 12:50PM - 1:40PM @ Ballroom E
50 minutes conference
Global Transaction ID (GTID) is one of the most compelling new features of MySQL 5.6. It is also one of the trickiest to deploy to an existing large-scale environment. This talk will cover every aspect of how and why we adopted GTID at Facebook, including: * Benefits and use-cases * Comparison of different GTID implementations * A failover technique to easily replay missing transactions on replicas * Combining GTID with semi-synchronous replication * Changes we made to Facebook's version of the MySQL Server to simplify deployment, fix crash-safety, improve slave reconnection performance, and more * Operational rollout and automation across many thousands of MySQL instances This session is geared towards DBAs and database engineers. Attendees will gain a full understanding of how GTID works, why it's beneficial, and how to deploy it at any scale.
