Register a Databricks Unity Catalog Connection

Public preview

This feature is public preview and available to select accounts. Reach out to your Immuta support professional to enable it on your tenant.

Requirements

Prerequisites

• Unity Catalog metastore created and attached to a Databricks workspace. See the Databricks Unity Catalog reference guide for information on workspaces and catalog isolation support with Immuta.

• Unity Catalog enabled on your Databricks cluster or SQL warehouse. All SQL warehouses have Unity Catalog enabled if your workspace is attached to a Unity Catalog metastore. Immuta recommends linking a SQL warehouse to your Immuta tenant rather than a cluster for both performance and availability reasons.

Register a connection

1. Click Data and select the Infrastructure tab in the navigation menu.

2. Click the + Add Host button.

3. Select the Databricks data platform tile.

4. Enter the connection information:

   • Host: The hostname of your Databricks workspace.

   • Port: Your Databricks port.

   • HTTP Path: The HTTP path of your Databricks cluster or SQL warehouse.

   • Immuta Catalog: The name of the catalog Immuta will create to store internal entitlements and other user data specific to Immuta. This catalog will only be readable for the Immuta service principal and should not be granted to other users. The catalog name may only contain letters, numbers, and underscores and cannot start with a number.

   • Connection Key: The connection key represents the unique name of your connection and will be used as prefix in the name for all data objects associated with this connection. It will also appear as the display name in the UI and will be used in all API calls made to update or delete the connection.

5. Click Next.

6. Select Access Token authentication method from the dropdown menu.

7. Enter the Access Token in the Immuta System Account Credentials section. This is the access token for the Immuta service principal. This service principal must have the metastore privileges listed in the requirements section at the top of this page for the metastore associated with the Databricks workspace. If this token is configured to expire, update this field regularly for the integration to continue to function. This authentication information will be included in the script populated later on the page.

8. Copy the provided script and run it in Databricks as a user with the CREATE CATALOG privilege on the Unity Catalog metastore.

9. Click Validate Connection.

10. If the connection is successful, click Next. If there are any errors, check the connection details and credentials to ensure they are correct and try again.

11. Ensure all the details are correct in the summary and click Complete Setup.
