Got it. I'm asking because I worked on something similar. The idea was to unit test some Airflow workflows locally. The production workflows were using Hive, but having a local Hive container was too slow for tests, so we wrote a small parser to translate the Hive queries into SQLite queries at runtime. In the end, we had a decent PoC but couldn't complete it because of all the Hive features, but it was super fun.
