# Data Task Stability

## Overview

The `oxla_data_task_stability` table provides information about the stability of data tasks for tables within Oxla.

* Data tasks are background processes responsible for normalizing and maintaining data layouts
* The stability status indicates whether the table's files have been processed and are up-to-date
* Regardless of the stability status the table is ready to be queried

## Example

When running the command below:

```sql  theme={null}
SELECT * FROM oxla_internal.oxla_data_task_stability;
```

you will get the following output:

```sql  theme={null}
 table_id | namespace_id | database_id | is_stable 
----------+--------------+-------------+-----------
    16384 |            0 |           0 | t
(1 row)
```

| Column Name    | Data Type | Constraints | Description                                                                                                                                                                                                                                    |
| -------------- | --------- | ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `table_id`     | `BIGINT`  | `NOT NULL`  | Unique identifier for the table                                                                                                                                                                                                                |
| `namespace_id` | `BIGINT`  | `NOT NULL`  | Identifier for the namespace that the table belongs to                                                                                                                                                                                         |
| `database_id`  | `BIGINT`  | `NOT NULL`  | Identifier for the database where the table is located                                                                                                                                                                                         |
| `is_stable`    | `BOOL`    | `NOT NULL`  | Indicates the state of the data task. `false` means the files are either being processed or queued for processing. `true` means the files have been processed, are stable and this state persists until the user updates the data in the table |

<Note>You can join the `table_id`, `namespace_id` and `database_id` columns with other virtual tables to obtain human-readable names for the table, namespace and database</Note>
