One of the problems with Ceph is that it doesn't operate at the highest possible throughput or the lowest possible latency point.

DAOS seemed promising a couple of years ago. But in terms of popularity it seems to be stuck. No Ubuntu packages, no wide spread deployment, Optane got killed.

Yet the NVMe + metadata approach seemed promising.

Would love to see more databases fork it to do what you need from it.

Or if folks have looked at it and decided not to do it, an analysis of why would be super interesting.
