Values.FailoverDBClusterMessageSourceForces a failover for a DB cluster. A failover for a DB cluster promotes one of the Read Replicas (read-only instances) in the DB cluster to be the primary instance (the cluster writer). Amazon Neptune will automatically fail over to a Read 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.
type nonrec t = {dBClusterIdentifier : String_.t option;A DB cluster identifier to force a failover for. This parameter is not case-sensitive. Constraints: Must match the identifier of an existing DBCluster.
*)targetDBInstanceIdentifier : String_.t option;The name of the instance to promote to the primary instance. You must specify the instance identifier for an Read Replica in the DB cluster. For example, mydbcluster-replica1.
