Step 4: Deleting a cluster - Amazon MemoryDB for Redis

Step 4: Deleting a cluster

As long as a cluster is in the available state, you are being charged for it, whether or not you are actively using it. To stop incurring charges, delete the cluster.

Warning

When you delete a MemoryDB cluster, your manual snapshots are retained. You can also create a final snapshot before the cluster is deleted. Automatic snapshots are not retained. For more information, see Snapshot and restore .

The following procedure deletes a single cluster from your deployment. To delete multiple clusters, repeat the procedure for each cluster that you want to delete. You do not need to wait for one cluster to finish deleting before starting the procedure to delete another cluster.

To delete a cluster

  1. Sign in to the AWS Management Console and open the MemoryDB for Redis console at https://console.aws.amazon.com/memorydb/.

  2. To choose the cluster to delete, choose the radio button next to the cluster's name from the list of clusters. In this case, the name of the cluster you created at Step 1: Create a cluster.

  3. For Actions, choose Delete.

  4. First choose whether to create a snapshot of the cluster before deleting it and then enter delete in the confirmation box and Delete to delete the cluster, or choose Cancel to keep the cluster.

    If you chose Delete, the status of the cluster changes to deleting.

As soon as your cluster is no longer listed in the list of clusters, you stop incurring charges for it.

The following code deletes the cluster my-cluster. In this case, substitute my-cluster with the name of the cluster you created at Step 1: Create a cluster.

aws memorydb delete-cluster --cluster-name my-cluster

The delete-cluster CLI operation only deletes one cluster. To delete multiple clusters, call delete-cluster for each cluster that you want to delete. You do not need to wait for one cluster to finish deleting before deleting another.

For Linux, macOS, or Unix:

aws memorydb delete-cluster \
    --cluster-name my-cluster \
    --region us-east-1

For Windows:

aws memorydb delete-cluster ^
    --cluster-name my-cluster ^
    --region us-east-1

For more information, see delete-cluster.

The following code deletes the cluster my-cluster. In this case, substitute my-cluster with the name of the cluster you created at Step 1: Create a cluster.

https://memory-db.us-east-1.amazonaws.com/    
    ?Action=DeleteCluster

The DeleteCluster API operation only deletes one cluster. To delete multiple clusters, call DeleteCluster for each cluster that you want to delete. You do not need to wait for one cluster to finish deleting before deleting another.
