.NET Framework 4.5
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.
