Or just use Clickhouse.
Your data catalog point remains, it doesn’t offer anything other basic SQL describe functionality.
I have rarely seen data people familiar with K8s as they mostly use managed services, but feel free to prove me wrong!
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.
Using popularity as justification of anything is the definition of slippery slope.
