Good luck with your project, FDB fucked it's users back in 2015 when it abruptly closed shop and went closed source. Hopefully some good can come of it yet.
It has significant usage across large companies such as Apple, Snowflake, Epic Games, VMWare, etc. I don't see it going closed source. Besides that, here Tigris is taking the responsibility for the product as it is abstracting FoundationDB from the end-user.
I can assure you from FDB will not be closed sourced again. But I agree that it was pretty bad for its [open source] users that it was made closed source. Terrible move for adoption.
Many of those users continued to be users, with source licenses, who are users to this day. If you had a commercial contract you were unaffected. Perhaps not if you were freeloading…
