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.

<a name="serverless-workgroup-query-limits"></a>

Under the **Limits** tab for a workgroup, you can add a limit to monitor performance and limits. For more information about query monitoring limits, see [WLM query monitoring rules](https://docs.aws.amazon.com/redshift/latest/dg/cm-c-wlm-query-monitoring-rules.html).

1. Choose **Manage query limits**. Choose **Add new limit** on the **Manage query limits** dialogue.

1. Choose the limit type you want to set and enter a value for its corresponding limit.

1. Choose **Save changes** to save the limit.

When you change your query limit and configuration parameters, your database will restart.
