Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025. If you would like to use Python UDFs, create the UDFs prior to that date. Existing Python UDFs will continue to function as normal. For more information, see the blog post .

REBOOT_CLUSTER

Reboot the Amazon Redshift cluster without closing the connections to the cluster. You must be a database superuser to run this command.

After this soft reboot has completed, the Amazon Redshift cluster returns an error to the user application and requires the user application to resubmit any transactions or queries interrupted by the soft reboot.

Syntax

SELECT REBOOT_CLUSTER();
