Show answer and explanation
Correct answers: A, B, C
Explanation
Creating a feature store table in Unity Catalog involves defining and registering the table schema, writing feature data using the Feature Store client, and managing access permissions through Unity Catalog. These steps ensure that features are stored, discoverable, and accessible securely. Unity Catalog complements the Feature Store but does not replace the need for the Feature Store client.
- A. Correct.
Correct: Defining a feature table schema and registering it with Unity Catalog is a necessary first step to create a feature store table.
- B. Correct.
Correct: Writing computed feature data to the feature store table using the Feature Store client ensures the data is properly stored and managed within the feature store.
- C. Correct.
Correct: Granting access permissions using Unity Catalog ensures that the feature store table can be securely accessed by appropriate users or teams.
- D. Incorrect.
Incorrect: The Delta Lake library is already integrated into Databricks, so no separate installation is required before creating a feature store table.
- E. Incorrect.
Incorrect: While Unity Catalog is used to manage feature tables, the Feature Store client is required to interact with the feature store. Unity Catalog alone cannot directly create a feature table.
