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. 

# STV\_XRESTORE\_ALTER\_QUEUE\_STATE
<a name="r_STV_XRESTORE_ALTER_QUEUE_STATE"></a>

Use STV\_XRESTORE\_ALTER\_QUEUE\_STATE to monitor the migration progress of each table during a classic resize. This is specifically applicable when the target node type is RG or RA3. For more information about classic resize to RG or RA3 nodes, go to [Classic resize](https://docs.aws.amazon.com/redshift/latest/mgmt/managing-cluster-operations.html#classic-resize-faster).

STV\_XRESTORE\_ALTER\_QUEUE\_STATE is visible only to superusers. For more information, see [Visibility of data in system tables and views](cm_chap_system-tables.md#c_visibility-of-data).

Some or all of the data in this table can also be found in the SYS monitoring view [SYS\_RESTORE\_STATE](SYS_RESTORE_STATE.md). The data in the SYS monitoring view is formatted to be easier to use and understand. We recommend that you use the SYS monitoring view for your queries.
