Public API v2 → Create External Schema Endpoint

About the /extraction/schema endpoint

The /extraction/schema endpoint creates a new external schema in the Spark Metastore for data extraction from verified business views. Only schemas defined in the CMC can be used in the data extraction endpoints.

Before using this endpoint, you must set the required configurations, such as enabling and configuring Advanced SQLi and setting the CMC configurations. For more information, refer to References → Data Extraction via Advanced SQLi and Public API.

This endpoint is the first of a series of endpoints that you use to extract data from verified business views into Parquet files that can be stored in different destinations, such as Google Cloud Storage, AWS S3, Azure, or local drive. After creating the external schema, you can use the POST /extraction/table endpoint to extract data to a new table or replace files in existing table. Afterward, you can use the PUT /extraction/table endpoint to append data to the path of an existing external table. For more information, refer to References → Data Extraction via Advanced SQLi and Public API.

Only the Super admin user (and users with the SuperRole when the Super User Mode is enabled) can use this endpoint.

For information about how to get started with Public API v2, refer to References → Public API v2.

Note

Use the HTTPS or HTTP scheme according to your installation. You must use the HTTPS scheme to successfully run the API endpoints on Cloud installations.
