Show answer and explanation

Correct answers: A, B, D, E

Explanation

To create a feature store table in Unity Catalog, you need to ensure that Unity Catalog is enabled and you have access to the appropriate catalog and schema. You can use either the databricks.feature_store.create_feature_table() function or the FeatureStoreClient.create_table() method to define the table and write feature data. Additionally, setting up proper access control policies in Unity Catalog ensures that other teams can access and query the table as intended. Manually registering a Delta table in the Feature Store UI is not part of this workflow.

  • A. Correct.

    Correct: Unity Catalog must be enabled, and you need access to the catalog and schema to store a feature table.

  • B. Correct.

    Correct: The databricks.feature_store.create_feature_table() function allows you to specify the Unity Catalog schema and create a feature table.

  • C. Incorrect.

    Incorrect: Setting up a Delta table and registering it manually in the Feature Store UI is not a valid or required workflow for creating a feature store table in Unity Catalog.

  • D. Correct.

    Correct: Using the FeatureStoreClient.create_table() method with the correct catalog and schema parameters enables writing feature data to Unity Catalog.

  • E. Correct.

    Correct: Configuring access control policies is necessary to enable other teams to query and use the feature table stored in Unity Catalog.
