This is frustrating to read. Tigres is built on FoundationDB, but doesn't expose all FoundationDB operations like transactions, range reads, and get mapped range. They go through all sorts of complications to handle these issues, including a database for caching (and they don't consider thundering herd problems).

What if you just ran FoundationDB instead?

Would that let you do collaboration blog-posts with another VC-funded startup though?

FoundationDB is only as metadata store.

Also, the database is the last thing you want to re-invent unless your business is explicitly building a db (even then it's best to re-use a db like all the postgresql forks that have existed)
