Actually I think Convex team are right, synchronous functions or database views would be huge improvement to Firebase.

Firebase Functions are asynchronous, and can be reordered relative to DB operations. They would be much more powerful if synchronous and on the wrtie path (so you could put auth logic in them instead of being forced to use the bespoke security language).

Firebase functions are at-least-once though, so they are pretty good but could be better.
