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.

SVV\_ACTIVE\_CURSORS displays details for currently open cursors. For more information, see [DECLARE](declare.md). 

SVV\_ACTIVE\_CURSORS is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see [Visibility of data in system tables and views](cm_chap_system-tables.md#c_visibility-of-data). A user can only view cursors opened by that user. A superuser can view all cursors.
