delete_cache_cluster(**kwargs)¶Deletes a previously provisioned cluster. DeleteCacheCluster deletes all associated cache nodes, node endpoints and the cluster itself. When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the cluster; you cannot cancel or revert this operation.
This operation is not valid for:
