Serverless SQL pool has a very cool way to handle CREATE EXTERNAL TABLE AS SELECT (CETAS). I mean, you can use a serverless SQL pool to create a CETAS which will materialize the query results. It means a heavy query in which, for example, the results would be part of future large join with other queries or aggregations that can be consolidated for reporting purposes. Those scenarios are examples that could be used as a CETAS. CETAS will be stored as a parquet file accessed by an external table in your storage and the performance is awesome. Later I am suggesting how to recreate the CETAS using pipeline against serverless SQL Pool.
