What is mysql-agent?

• High Availability

  Master failure detection and automating master failover enables master switch in a few seconds.

• Brain Split Omission

  By configuring proper lease ttl, mysql-agent enables at most one master in the cluster at any time.

• Cross AZ Topology

  Leveraging etcd as the service discovery, mysql-agent prevent its implementation from VIP, so that the cross-AZ MySQL cluster is able to be build via mysql-agent.

• Manual Master/Slave Switch

  Besides the automated failover as described below, mysql-agent provides the ability to switch master manually.
