// A failover for a DB cluster promotes one of the Aurora Replicas (read-only
// instances) in the DB cluster to be the primary instance (the cluster writer).
//
// Amazon Aurora will automatically fail over to an Aurora Replica, if one exists,
// when the primary instance fails. You can force a failover when you want to
// simulate a failure of a primary instance for testing. Because each instance
// in a DB cluster has its own endpoint address, you will need to clean up and
// re-establish any existing connections that use those endpoint addresses when
// the failover is complete.
