Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/) that was published on June 30, 2025. 

# Shutting down and deleting a cluster
<a name="rs-mgmt-shutdown-delete-cluster"></a>

You can shut down your cluster if you want to stop it from running and incurring charges. When you shut it down, you can optionally create a final snapshot. If you create a final snapshot, Amazon Redshift will create a manual snapshot of your cluster before shutting it down. If you plan to provision a new cluster with the same data and configuration as the one you are deleting, you need a manual snapshot. By using a manual snapshot, you can restore the snapshot later and resume using the cluster. 

If you no longer need your cluster and its data, you can shut it down without creating a final snapshot. In this case, the cluster and data are deleted permanently.

Regardless of whether you shut down your cluster with a final manual snapshot, all automated snapshots associated with the cluster will be deleted after the cluster is shut down. Any manual snapshots associated with the cluster are retained. Any manual snapshots that are retained, including the optional final snapshot, are charged at the Amazon Simple Storage Service storage rate if you have no other clusters running when you shut down the cluster, or if you exceed the available free storage that is provided for your running Amazon Redshift clusters. For more information about snapshot storage charges, see the [Amazon Redshift pricing page](https://aws.amazon.com/redshift/pricing/). 

Deleting a cluster also deletes any associated AWS Secrets Manager secrets.

**To delete a cluster**

1. Sign in to the AWS Management Console and open the Amazon Redshift console at [https://console.aws.amazon.com/redshiftv2/](https://console.aws.amazon.com/redshiftv2/).

1. On the navigation menu, choose **Clusters**.

1. Choose the cluster to delete. 

1. For **Actions**, choose **Delete**. The **Delete cluster** page appears. 

1. Choose **Delete cluster**. 

**Note**  
When you delete a cluster and choose to create a final snapshot, Amazon Redshift will stop the delete request if a restore operation is in progress on the cluster. If this occurs, you can delete the cluster without a final snapshot, or you can delete it with a final snapshot after the restore completes.
