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://amazonaws-china.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# SVCS\$1S3LIST
<a name="r_SVCS_S3LIST"></a>

Use the SVCS\$1S3LIST view to get details about Amazon Redshift Spectrum queries at the segment level. One segment can perform one external table scan. This view is derived from the SVL\$1S3LIST system view but doesn't show slice-level for queries run on a concurrency scaling cluster. 

**Note**  
System views with the prefix SVCS provide details about queries on both the main and concurrency scaling clusters. The views are similar to the views with the prefix SVL except that the SVL views provide information only for queries run on the main cluster.

SVCS\$1S3LIST 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).

For information about SVL\$1S3LIST, see [SVL\$1S3LIST](r_SVL_S3LIST.md).
