Looker & DAG Workflows

Hey guys,

I came across a use case where too many transformations are needed in order to reach the end result. Some solutions rely on DAG workflows in such cases - for example Apache Spark or GCP Composer (Apache Airflow).

I could use one of these but then the beauty of Looker would be lost - I have to abandon the LookML definitions and go back to basic SQL.

So my question is - can this be achieved by somehow creating dependancies between PDTs or in any other way so the whole workflow of transformations would become more visible.

Sorry if my explanation is not clear enough, ready to answer any questions.
