Overview

This node operation lists functions within the Unity Catalog in Databricks. It allows filtering the functions by optional catalog and schema names, enabling users to retrieve a list of functions scoped to specific catalog and schema contexts. This is useful for managing and exploring available functions in a data governance environment.

Use Case Examples

1. List all functions in the Unity Catalog without filters.
2. List functions filtered by a specific catalog name.
3. List functions filtered by both catalog and schema names.

Properties

Output

JSON

• name - The full name of the function including catalog and schema.
• value - The identifier or value representing the function.
• description - Description of the function including catalog, schema, and data type if available.
• url - URL to explore the function details in the Databricks UI.

Dependencies

• Databricks API with appropriate authentication token

Troubleshooting

• Ensure the catalog and schema names are correctly specified and exist in the Unity Catalog to avoid empty results.
• API authentication errors may occur if the API token is invalid or expired; verify credentials.
• Network errors can happen if the Databricks host URL is incorrect or unreachable.
• If the node returns an error about volume path format, it is unrelated to this operation but indicates input format issues in other operations.
