If you want to shut down the cluster and retain it for future use, set SkipFinalClusterSnapshot to false
and specify a name for FinalClusterSnapshotIdentifier. You can later restore this snapshot to resume using the cluster. If a final cluster snapshot is requested, the status of the cluster will be "final-snapshot" while the snapshot is being taken, then it's "deleting" once Amazon Redshift begins deleting the cluster.
For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide.
