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/). 

# STL\$1COMMIT\$1STATS
<a name="r_STL_COMMIT_STATS"></a>

Provides metrics related to commit performance, including the timing of the various stages of commit and the number of blocks committed. Query STL\$1COMMIT\$1STATS to determine what portion of a transaction was spent on commit and how much queuing is occurring.

STL\$1COMMIT\$1STATS 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).

Some or all of the data in this table can also be found in the SYS monitoring view [SYS\$1TRANSACTION\$1HISTORY](SYS_TRANSACTION_HISTORY.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.

## Sample query

```
select node, datediff(ms,startqueue,startwork) as queue_time, 
datediff(ms, startwork, endtime) as commit_time, queuelen
from stl_commit_stats
where xid = 2574
order by node;

node | queue_time   | commit_time | queuelen
-----+--------------+-------------+---------
  -1 |            0 |         617 |        0
   0 | 444950725641 |         616 |        0
