I don't recommend overpriced SaaS solutions; I highlight that there is a lesson to be learned on why they're so popular, and open-source tech could be as simple as them.
That's why I started Universql in the first place; use their interface/protocol as an open-source tech and reduce the compute cost (often ~90% of the total cost of DWHs) by using DuckDB. You still get all the catalog features without paying the premium price.
I have rarely seen data people familiar with K8s as they mostly use managed services, but feel free to prove me wrong!
