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\$1S3QUERY\$1SUMMARY
<a name="r_SVL_S3QUERY_SUMMARY"></a>

Use the SVL\$1S3QUERY\$1SUMMARY view to get a summary of all Amazon Redshift Spectrum queries (S3 queries) that have been run on the system. SVL\$1S3QUERY\$1SUMMARY aggregates detail from SVL\$1S3QUERY at the segment level.

SVL\$1S3QUERY\$1SUMMARY 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).

Some or all of the data in this table can also be found in the SYS monitoring view [SYS\$1EXTERNAL\$1QUERY\$1DETAIL](SYS_EXTERNAL_QUERY_DETAIL.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.

For SVCS\$1S3QUERY\$1SUMMARY, see [SVCS\$1S3QUERY\$1SUMMARY](r_SVCS_S3QUERY_SUMMARY.md).

## Sample query
<a name="r_SVL_S3QUERY_SUMMARY-sample-query"></a>

The following example gets the scan step details for the last query completed.

```
select query, segment, elapsed, s3_scanned_rows, s3_scanned_bytes, s3query_returned_rows, s3query_returned_bytes, files 
from svl_s3query_summary 
where query = pg_last_query_id() 
order by query,segment;
```

```
query | segment | elapsed | s3_scanned_rows | s3_scanned_bytes | s3query_returned_rows | s3query_returned_bytes | files
