Obviously, that depends on how the database is defined and if the
queries are half-decent (so that not everything has to fall back to
full table scans).

And it's not just about processing time.  With small VMs and
containers, it's also about not putting everything into RAM.

I think SQLite would be the better choice, after comparing the
upstream reactions (not features) when discussing RPM's special
requirements with them (key sizes, read-only access without locking).
