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. 

# SVL\_FEDERATED\_QUERY
<a name="r_SVL_FEDERATED_QUERY"></a>

Use the SVL\_FEDERATED\_QUERY view to view information about a federated query call.

SVL\_FEDERATED\_QUERY 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\_EXTERNAL\_QUERY\_DETAIL](SYS_EXTERNAL_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.

## Table columns
<a name="SVL_FEDERATED_QUERY-table-columns"></a>


| Column name  | Data type  | Description  | 
| --- | --- | --- | 
| userid | integer  | The ID of the user running the query. | 
| xid | bigint | The transaction ID. | 
| pid | integer | The ID of the leader process running the query.  | 
| query | integer | The query ID of a federated call. | 
| sourcetype | character (32) | The federated call source type, for example "PG".  | 
| recordtime | timestamp | The time when a query is sent for federation. UTC is used. | 
| querytext | character (4000) | The query string sent to the remote PostgreSQL engine for execution. | 
| num\_rows | bigint | The number of rows returned by the federated query. | 
| num\_bytes | bigint | The number of bytes returned by the federated query. | 
| duration | bigint | The time (microseconds) spent fetching rows from cursor calls. It is the time spent running the federated query, as well as, getting results back. | 

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

To show information about federated query calls, run the following query.

```
select query, trim(sourcetype) as type, recordtime, trim(querytext) as "PG Subquery" from svl_federated_query where query = 4292;
                
 query | type |         recordtime         |                          pg subquery
-------+------+----------------------------+---------------------------------------------------------------
  4292 | PG   | 2020-03-27 04:29:58.485126 | SELECT "level" FROM functional.employees WHERE ("level" >= 6)
(1 row)
```
