Delete Tables - Maia Documentation

The Delete Tables orchestration component lets you delete a list of tables in a single operation. It generates a single DROP TABLE statement, optionally with IF EXISTS and CASCADE modifiers. Note that the Delete Tables component has more in common with the Snowflake DROP TABLE statement than the DELETE statement. For detailed information on DROP TABLE in Snowflake, refer to the Snowflake documentation. This component may be used inside a transaction. However, on rollback, deleted tables will NOT be restored.
