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\$1QUERY\$1METRICS\$1SUMMARY
SVL\$1QUERY\$1METRICS\$1SUMMARY

The SVL\$1QUERY\$1METRICS\$1SUMMARY view shows the maximum values of metrics for completed queries. This view is derived from the [STL\$1QUERY\$1METRICS](r_STL_QUERY_METRICS.md) system table. Use the values in this view as an aid to determine threshold values for defining query monitoring rules. For more information about rules and metrics for query monitoring for Amazon Redshift, see [WLM query monitoring rules](cm-c-wlm-query-monitoring-rules.md).

SVL\$1QUERY\$1METRICS\$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\$1QUERY\$1DETAIL](SYS_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.
