Forces 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.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginFailoverDBCluster and EndFailoverDBCluster.
public abstract Task<FailoverDBClusterResponse> FailoverDBClusterAsync( FailoverDBClusterRequest request, CancellationToken cancellationToken )
Container for the necessary parameters to execute the FailoverDBCluster service method.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
