Abstract

In this talk Yoshinori will introduce a newly announced MySQL master failover tool: MHA (http://code.google.com/p/mysql-master-ha/). By using MHA, when master is down, one of the new slaves will automatically become new master, and other slaves will automatically replicate from the new master. Consistency issues (in case of the master crash, relay log states on slaves might be different each other) will automatically be fixed, and you can install MHA on existing MySQL replication environments without stopping MySQL. He'll explain the details of MHA, and how to use and how we use MHA on our environments.
