At Facebook, we created MyRocks (RocksDB Storage Engine for MySQL) a few years ago. Since then, we have migrated from InnoDB to MyRocks in our top three largest database services, including Facebook Messenger. On the other hand, we still have many InnoDB instances, especially for general purpose use cases. At previous Percona Live conferences, I spoke about how we migrated from InnoDB to MyRocks. In this session, I am going to talk more about lessons learned after migration. Topics like what kinds of production issues we faced will be covered. I am also going to talk about how we migrated Facebook Messenger -- from HBase to MyRocks.
Yoshinori Matsunobu is a Production Engineer at Facebook, and now is leading MyRocks project. Yoshinori has been around MySQL community for over 10 years, and was a senior consultant at MySQL Inc since 2006 to 2010. Yoshinori created a couple of useful open source product/tools, including MHA (automated MySQL master failover tool) and quickstack.
