Overview

This node operation lists volumes within the Unity Catalog in Databricks. It allows filtering volumes by catalog and schema names optionally. This is useful for users who want to retrieve and manage storage volumes in their Databricks Unity Catalog environment, enabling them to see available volumes under specific catalogs and schemas.

Use Case Examples

1. List all volumes across all catalogs and schemas.
2. List volumes filtered by a specific catalog name.
3. List volumes filtered by both catalog and schema names.

Properties

Output

JSON

• volumes - Array of volume objects returned by the Unity Catalog API, each representing a volume with details such as name, description, and type.

Dependencies

• Databricks API with appropriate authentication token
• Unity Catalog API endpoints

Troubleshooting

• Ensure the catalog and schema names are correctly specified and exist in the Unity Catalog.
• Check that the API authentication token is valid and has permissions to access Unity Catalog resources.
• If no volumes are returned, verify that volumes exist under the specified catalog and schema.
• Handle API errors gracefully, such as network issues or permission denials.
