Engineer working on Deno KV here. Building on FDB is mostly a pleasant experience since it solves the hard part of the problem for us (concurrency control and persisting mutations).
We sometimes run into its limitations - the way we are using FDB is a bit beyond what it was originally designed for. But when it works, it works great.
