Diancheng Wang (Alibaba Cloud), Guangchao Bai (Alibaba Cloud) delivers the talk, "How to make MySQL work with Raft", on DAY 1 of the Percona Live Open Source Database Conference 2018, 4/24, at Santa Clara, CA. For the cloud environment, we hope MySQL cluster can do the failover and choose the new master node by the instance-self automatically, without third-party middleware. So we built the Raft protocol inside MySQL. In MySQL-Raft version, every cluster usually has three nodes, one master and two slaves, but we can support more nodes. When the master node is down, the cluster can choose the new master by Raft Protocol, and use Flashback to rollback the committed transactions if needed, to make sure all of the nodes are the same.
