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\$1QUEUE\$1INFO
<a name="r_SVL_QUERY_QUEUE_INFO"></a>

Summarizes details for queries that spent time in a workload management (WLM) query queue or a commit queue. 

The SVL\$1QUERY\$1QUEUE\$1INFO view filters queries performed by the system and shows only queries performed by a user. 

The SVL\$1QUERY\$1QUEUE\$1INFO view summarizes information from the [STL\$1QUERY](r_STL_QUERY.md), [STL\$1WLM\$1QUERY](r_STL_WLM_QUERY.md), and [STL\$1COMMIT\$1STATS](r_STL_COMMIT_STATS.md) system tables. 

SVL\$1QUERY\$1QUEUE\$1INFO 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).

## Sample queries
<a name="r_SVL_QUERY_QUEUE_INFO-sample-queries"></a>

The following example shows the time that queries spent in WLM queues.

```
select query, service_class, queue_elapsed, exec_elapsed, wlm_total_elapsed
from svl_query_queue_info
where wlm_total_elapsed > 0;

  query  | service_class | queue_elapsed | exec_elapsed | wlm_total_elapsed
---------+---------------+---------------+--------------+-------------------
 2742669 |             6 |             2 |          916 |                918 
 2742668 |             6 |             4 |          197 |                201
