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\$1DATASHARE\$1CROSS\$1REGION\$1USAGE
<a name="r_SVL_DATASHARE_CROSS_REGION_USAGE"></a>

Use the SVL\$1DATASHARE\$1CROSS\$1REGION\$1USAGE view to get a summary of cross-Region data transferred usage caused by cross-Region datasharing query. SVL\$1DATASHARE\$1CROSS\$1REGION\$1USAGE aggregates details at the segment level.

SVL\$1DATASHARE\$1CROSS\$1REGION\$1USAGE 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\$1DATASHARE\$1CROSS\$1REGION\$1USAGE](r_SYS_DATASHARE_CROSS_REGION_USAGE.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 queries
<a name="r_SVL_DATASHARE_CROSS_REGION_USAGE-sample-queries"></a>

The following example shows a SVL\$1DATASHARE\$1CROSS\$1REGION\$1USAGE view.

```
SELECT query, segment, transferred_data, source_region
from svl_datashare_cross_region_usage
where query = pg_last_query_id()
order by query,segment;

  query | segment | transferred_data | source_region 
--------+---------+------------------+---------------
 200048 |       2 |          4194304 |    us-west-1  
 200048 |       2 |          4194304 |    us-east-2
