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\_MV\_REFRESH\_STATUS
The SVL\_MV\_REFRESH\_STATUS view contains a row for the refresh activity of materialized views.
For more information about materialized views, see [Materialized views in Amazon Redshift](materialized-view-overview.md).
SVL\_MV\_REFRESH\_STATUS 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\_MV\_REFRESH\_HISTORY](SYS_MV_REFRESH_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.
## Table columns
| Column name | Data type | Description |
| --- | --- | --- |
| db\_name | char(128) | The database that contains the materialized view. |
| userid | bigint | The ID of the user who performed the refresh. |
| schema\_name | char(128) | The schema of the materialized view. |
| mv\_name | char(128) | The materialized view name. |
| xid | bigint | The transaction ID of the refresh. |
| starttime | timestamp | The start time of the refresh. |
| endtime | timestamp | The end time of the refresh. |
| status | text | The status of the refresh. Example values include the following: [See the AWS documentation website for more details](http://docs.aws.amazon.com/redshift/latest/dg/r_SVL_MV_REFRESH_STATUS.html) |
| refresh\_type | char(32) | The definition of the refresh type. Example values include Manual and Auto. |
| consumer\_account | char(12) | The AWS account ID of the consumer cluster that initiated the refresh. This field is populated when the refresh is initiated from a consumer cluster in a data sharing setup. |
| consumer\_region | char(32) | The AWS Region of the consumer cluster that initiated the refresh. This field is populated when the refresh is initiated from a consumer cluster in a data sharing setup. |
| consumer\_namespace | char(36) | The namespace identifier of the consumer cluster that initiated the refresh. This field is populated when the refresh is initiated from a consumer cluster in a data sharing setup. |
## Sample query
To view the refresh status of materialized views, run the following query.
```
select * from svl_mv_refresh_status;
```
This query returns the following sample output:
```
db_name | userid | schema | name | xid | starttime | endtime | status | refresh_type | consumer_account | consumer_region | consumer_namespace
