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/). 

# SYS\$1RESTORE\$1STATE
<a name="SYS_RESTORE_STATE"></a>

Use SYS\$1RESTORE\$1STATE to monitor the migration progress of each table during a classic resize. This is specifically applicable when the target node type is RA3. For more information about classic resize to RA3 nodes, see [Classic resize](https://docs.aws.amazon.com/redshift/latest/mgmt/managing-cluster-operations.html#classic-resize-faster).

SYS\$1RESTORE\$1STATE 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).

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

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/redshift/latest/dg/SYS_RESTORE_STATE.html)

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

The following query returns records for running and queued queries.

```
SELECT * FROM sys_restore_state;
```

Sample output.

```
 userid | database_name | schema_id | table_id |   table_name   | redistribution_status | precentage_redistributed |   redistribution_type
--------+---------------+-----------+----------+----------------+-----------------------+--------------------------+-------------------------
    1   |     test1     |   124865  |  124878  | customer_key_4 |         Pending       |      0                   |  Rebalance Disteven Table
    1   |      dev      |   124865  |  124874  | customer_key_3 |         Pending       |      0                   |  Rebalance Disteven Table
    1   |      dev      |   124865  |  124870  | customer_key_2 |        Completed      |     100                  |  Rebalance Disteven Table
    1   |      dev      |   124865  |  124866  | customer_key_1 |       In progress     |     13.52                |  Restore Distkey Table
```

The following gives you the data-processing status.

```
SELECT
    redistribution_status, ROUND(SUM(block_count) / 1024.0, 2) AS total_size_gb
FROM sys_restore_state sys inner join stv_tbl_perm stv
    on sys.table_id = stv.id
GROUP BY sys.redistribution_status;
```

Sample output.

```
 redistribution_status | total_size_gb 
-----------------------+---------------
 Completed             |          0.07
 Pending               |          0.71
 In progress           |          0.20
(3 rows)
