> do they have a feature store with built in time-travel functionality?
My feature store hasn't supported time-travel yet. But many SaaS implementations do, including Tecton, Hopswork, Splice Machine, etc. Open source feature stores haven't implemented this critical feature AFAIK.

Haha, I do. Actually I am thinking about implementing feature stores using some "old-school" DB technology. By the way, just curious since I've never used PL/SQL: Are you able to implement the time-travel functionality using pure SQL?
