📄️ CREATE EXTERNAL CATALOG
CREATE EXTERNAL CATALOG creates an external catalog. You can use external catalogs to query data in external data sources without loading data into StarRocks or creating external tables. Currently, you can create the following types of external catalogs:
📄️ DROP CATALOG
DROP CATALOG deletes an external catalog. The internal catalog cannot be deleted. A StarRocks cluster has only one internal catalog named default_catalog.
📄️ SET CATALOG
Switches to a specified catalog in the current session.
📄️ SHOW CATALOGS
SHOW CATALOGS queries all catalogs in the current StarRocks cluster, including the internal catalog and external catalogs.
📄️ SHOW CREATE CATALOG
SHOW CREATE CATALOG queries the creation statement of an external catalog.
