Overview

This node interacts with the Databricks Unity Catalog API to list all catalogs available in the Unity Catalog service. It is useful for users who want to retrieve and manage metadata about data catalogs within Databricks' unified governance framework. For example, it can be used to fetch a list of catalogs to display in a UI or to automate workflows that require catalog information.

Use Case Examples

1. Retrieve all catalogs in Unity Catalog to display in a dashboard.
2. Automate the process of auditing or managing data catalogs by fetching their details programmatically.

Output

JSON

• json
  • catalogs - Array of catalog objects returned by the Unity Catalog API, each representing a data catalog with its metadata.

Dependencies

• Databricks API with an API token for authentication

Troubleshooting

• Ensure the Databricks API credentials (host and token) are correctly configured and have the necessary permissions to access Unity Catalog.
• If the API returns an error, check the network connectivity and the validity of the token.
• The node expects no input properties for this operation; providing unexpected inputs may cause errors.
