Overview

This node operation retrieves detailed information about a specific function within the Unity Catalog resource of Databricks. It is useful for users who need to access metadata or properties of a function defined in a catalog schema, such as for auditing, documentation, or integration purposes. For example, a user can specify the full name of a function in the format 'catalog.schema.function' to fetch its details via the Databricks API.

Use Case Examples

1. Retrieve metadata of a function named 'main.default.my_function' in Unity Catalog to verify its input parameters and return type.
2. Fetch details of a specific function to use its definition in automated workflows or data governance processes.
