Greetings!

Does Everest support a configuration to prevent downtime when MySQL primary instances go down (failover)? If not, is there any planned support?

Hi! Everest uses Percona XtraDB Cluster under the hood. In other words, if you choose 3 or 5 MySQL nodes, it will automatically failover to another healthy instance in case of a failure.
