Forces a failover for a DB cluster.

A failover for a DB cluster promotes one of the read-only instances in the DB cluster to the master DB instance (the cluster writer) and deletes the current primary instance.

Amazon Aurora will automatically fail over to a read-only instance, if one exists, when the primary instance fails. You can force a failover when you want to simulate a failure of a DB 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.

For more information on Amazon Aurora, see Aurora on Amazon RDS ( in the Amazon RDS User Guide.
