Synchronous multi-master clusters with MySQL: an introduction to Galera

A session at OUG Harmony 2012

Friday 1st June, 2012

1:00pm to 2:00pm (RMT)

MySQL high-availability has usually been an exercise in tradeoffs: You can choose asynchronous replication and risk losing committed transactions on a failure. You can choose disk based (DRBD, SAN) replication for better durability but longer failover downtime. And in all cases you will end up taking a performance hit to achieve HA, not to mention the swearing due to inconsistent slave and other operational headaches. Galera replication, developed by Helsinki based Codership Oy, has finally raised the bar for MySQL HA: You will learn how Galera brings synchronous, true multi-master and high performance (parallel slaves) replication.

Henrik Ingo works as Senior Performance Architect at Nokia. Previously he has worked with MySQL AB and Sun and became an expert both in MySQL and MySQL Cluster performance and high-availability. He remains active with everything going on in the MySQL community. He is also a visible open source advocate and author of the book: Open Life: The Philosophy of Open Source (www.openlife.cc).
