How are you using Databricks in your company?

Hello. I have many years of experience, but I've never worked with Databricks, and I'm planning to learn it on my own. I just signed up for the free edition and there are a ton of different menus for different features, so I was wondering how every company uses Databricks, to narrow the scope of what I need to learn.

Do you mostly use it just as a Spark compute engine? And then trigger Databricks jobs from Airflow/other schedules? Or are other features actually useful?

Thanks!
