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/). 

# SVCS\$1UNLOAD\$1LOG
<a name="r_SVCS_UNLOAD_LOG"></a>

Use the SVCS\$1UNLOAD\$1LOG to get details of UNLOAD operations.

SVCS\$1UNLOAD\$1LOG records one row for each file created by an UNLOAD statement. For example, if an UNLOAD creates 12 files, SVCS\$1UNLOAD\$1LOG contains 12 corresponding rows. This view is derived from the STL\$1UNLOAD\$1LOG system table 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 tables with the prefix STL except that the STL tables provide information only for queries run on the main cluster.

SVCS\$1UNLOAD\$1LOG 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).

## Sample query
<a name="r_SVCS_UNLOAD_LOG-sample-query"></a>

To get a list of the files that were written to Amazon S3 by an UNLOAD command, you can call an Amazon S3 list operation after the UNLOAD completes; however, depending on how quickly you issue the call, the list might be incomplete because an Amazon S3 list operation is eventually consistent. To get a complete, authoritative list immediately, query SVCS\$1UNLOAD\$1LOG.

The following query returns the path name for files that were created by an UNLOAD for the last query completed:

```
select query, substring(path,0,40) as path
from svcs_unload_log
where query = pg_last_query_id()
order by path;
```

This command returns the following sample output: 

```
 
 query |             path
