Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, 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/). 

# SVL\$1RESTORE\$1ALTER\$1TABLE\$1PROGRESS
<a name="r_SVL_RESTORE_ALTER_TABLE_PROGRESS"></a>

Use SVL\$1RESTORE\$1ALTER\$1TABLE\$1PROGRESS to monitor the migration progress of each table in the cluster during a classic resize to RA3 nodes. It captures the historic throughput of data migration during the resize operation. For more information about classic resize to RA3 nodes, go to [Classic resize](https://docs.aws.amazon.com/redshift/latest/mgmt/managing-cluster-operations.html#classic-resize-faster).

SVL\$1RESTORE\$1ALTER\$1TABLE\$1PROGRESS 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\$1RESTORE\$1LOG](SYS_RESTORE_LOG.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.

**Note**  
Rows with a progress of `100.00%` or `ABORTED` are deleted after 7 days. Rows for tables dropped during or after a classic resize can still appear in SVL\$1RESTORE\$1ALTER\$1TABLE\$1PROGRESS.
