Deleting a Cluster with Replicas

If you no longer need one of your clusters with replicas (called replication groups in the API/CLI), you can delete it. When you delete a replication group, ElastiCache deletes all of the nodes in that group.

Once you have begun this operation, it cannot be interrupted or cancelled.

Deleting a Replication Group (Console)

To delete a cluster that has replicas, see Deleting a Cluster.

Deleting a Replication Group (AWS CLI)

Use the command delete-replication-group to delete a replication group.

Copy
aws elasticache delete-replication-group --replication-group-id my-repgroup

A prompt asks you to confirm your decision. Enter y (yes) to start the operation immediately. After the process starts, it is irreversible.

						
   After you begin deleting this replication group, all of its nodes will be deleted as well.

Deleting a Replication Group (ElastiCache API)

Call DeleteReplicationGroup with the ReplicationGroup parameter.

Example

Copy
https://elasticache.us-west-2.amazonaws.com/ ?Action=DeleteReplicationGroup &ReplicationGroupId=my-repgroup &Version=2014-12-01 &SignatureVersion=4 &SignatureMethod=HmacSHA256 &Timestamp=20141201T220302Z &X-Amz-Algorithm=AWS4-HMAC-SHA256 &X-Amz-Date=20141201T220302Z &X-Amz-SignedHeaders=Host &X-Amz-Expires=20141201T220302Z &X-Amz-Credential=<credential> &X-Amz-Signature=<signature>

Note

If you set the RetainPrimaryCluster parameter to true, all of the read replicas will be deleted, but the primary cluster will be retained.
