Not at the latency needed for feature serving and most databases struggle with column limits.

But please enlighten us on which databases to use so Airbnb (and the rest of us) can stop wasting time.

Shameless plug, but XTDB v2 is being built for low-latency bitemporal queries over columnar storage and might be applicable: https://docs.xtdb.com/quickstart/query-the-past.html

We've not been developing v2 with ML feature serving in mind so far, but I would love to speak with anyone interested in this use case and figure out where the gaps are.
