Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, 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/) that was published on June 30, 2025. 

# query\_group
<a name="r_query_group"></a>

## Values (default in bold)
<a name="r_query_group-values"></a>

No default; the value can be any character string. 

## Description
<a name="r_query_group-description"></a>

Applies a user-defined label to a group of queries that are run during the same session. This label is captured in the query logs. You can use it to constrain results from the STL\_QUERY and STV\_INFLIGHT tables and the SVL\_QLOG view. For example, you can apply a separate label to every query that you run to uniquely identify queries without having to look up their IDs. 

This parameter doesn't exist in the server configuration file and must be set at runtime with a SET command. Although you can use a long character string as a label, the label is truncated to 30 characters in the LABEL column of the STL\_QUERY table and the SVL\_QLOG view (and to 15 characters in STV\_INFLIGHT). 

In the following example, query\_group is set to **Monday**, then several queries are run with that label.

```
set query_group to 'Monday';
SET
select * from category limit 1;
...
...
select query, pid, substring, elapsed, label
from svl_qlog where label ='Monday'
order by query;

query | pid  |        substring                   |  elapsed  | label
------+------+------------------------------------+-----------+--------
789   | 6084 | select * from category limit 1;    | 65468     | Monday
790   | 6084 | select query, trim(label) from ... | 1260327   | Monday
791   | 6084 | select * from svl_qlog where ..    | 2293547   | Monday
792   | 6084 | select count(*) from bigsales;     | 108235617 | Monday
...
