I imagine it was rhetorical, but as you probably imagined I have no suggestions. I understand your needs and imperatives, but they are unfortunately incompatible with mine. Getting a green light on using custom licence is near impossible. Procurement and contracting for database as service is also a nightmare.

I think mongo and elastic could get away with it because they already had captive users. For illustration, I didn't really look at your offering, I went to the licencing section and just summarily disqualified. I am also unlikely to use it personal pet projects, because the learnings cannot be leverage in my paying job.
