# Manage Data Sources and Data Source Settings

As a data owner, you can [edit your data source settings](#edit-a-data-source) and [disable](#disable-a-data-source), [delete](#delete-a-data-source), and [re-enable](#enable-a-disabled-data-source) a data source.

For other guides related to data source members and management, see the [Related guides section](#related-guides).

## Edit a data source

1. Navigate to the **Overview** tab.
2. Click the **more actions** icon in the upper right corner of the page and select **Edit**.
3. Change your settings in the data source workflow.

   *Note: Some settings cannot be changed once the data source has been created. In these cases, simply create a new data source with the new settings.*
4. When completed, navigate to the end of the workflow and click **Save**.

   *Note: Some data sources may require the data owner to reconnect to the remote database before any changes to the data source can be saved.*

For information on specific settings, see the [Create a data source guides](https://documentation.immuta.com/2025.1/configuration/integrations/registering-metadata/data-sources/register-data-sources).

### Bulk edit data sources

Data owners can bulk edit data sources.

1. Navigate to the data sources list page.
2. Select the checkboxes for the data sources you want to edit. *Note that when editing a connection string using bulk edit, all data sources from that connection must be selected.*
3. Select the action you want or click **More Actions** for additional options.
4. Confirm your edits by following the prompts in the modals that appear.

## Disable a data source

Disabling a data source hides it and its data from all users except the data owner. While in this state, the data source will display as disabled in the console for the data owner and other users will not be able to see it at all.

1. Navigate to the **Overview** tab.
2. Click on the **more actions** icon in the upper right corner and select **Disable**.

A label will appear next to the data source indicating it is now disabled, and a notification will be sent to all users of the data source informing them that the data source has been disabled.

{% hint style="info" %}
**Disabled data sources and Immuta policies**

By default, Immuta blocks access to data sources when they are disabled. To prevent Immuta from doing so, add the following snippet to the **Advanced Settings** section on the app settings page:

```yaml
featureFlags:
  noLockdownOnDisable: true
```

Once this feature flag is set to `true`, disabling a data source for one of the integrations below removes Immuta subscription and data policies from that data source; policies will not be applied until the data source is re-enabled:

* Azure Synapse Analytics
* Databricks Unity Catalog
* Google BigQuery
* Redshift
* Snowflake
  {% endhint %}

## Enable a disabled data source

1. Navigate to the **Overview** tab.
2. Click on the **more actions** icon in the upper right corner and select **Enable**.

A notification will be sent out to all users of the data source informing them that the data source has been enabled.

{% hint style="warning" %}
**Databricks Unity Catalog behavior**

If you enable a data source and it has no subscription policy set on it, Immuta will REVOKE access to the data in Databricks for all Immuta users, even if they had been directly granted access to the table in Unity Catalog.

If you disable a Unity Catalog data source in Immuta, all existing grants and policies on that object will be removed in Databricks for all Immuta users. All existing grants and policies will be removed, regardless of whether they were set in Immuta or in Unity Catalog directly.

If a user is not registered in Immuta, Immuta will have no effect on that user's access to data in Unity Catalog. See the [Databricks Unity Catalog reference guide](https://documentation.immuta.com/2025.1/configuration/databricks/databricks-unity-catalog/unity-catalog-overview#what-does-immuta-do-in-my-databricks-environment) for more details.
{% endhint %}

## Delete a data source

Deleting a data source permanently removes it from Immuta. Data sources must first be disabled before they can be deleted.

1. [Disable the data source](#disable-a-data-source).
2. Navigate to the **Overview** tab and click the **more actions** icon and select **Delete**.
3. Confirm that the data source should be deleted by clicking **Delete**.

A notification will be sent out to all users of the data source informing them that the data source has been deleted.
