Thanks. dbt is very cool and evolved at the same time but focuses on the Transform step of ETL only. Unfortunately, as data engineers, we still spend a lot of time consolidating the many input sources to perform that transformation and also want to load it to places.

You can see the work we have done to build standardised methods for Extract (https://arc.tripl.ai/extract/) and Load (https://arc.tripl.ai/load/) in the documentation.
