Latency would be the big issue here. You’d likely have to spin up instances in lots of key data centres to try and combat this...

Each AWS location, each Google Cloud location.. and that’s not considering those that are colocating their own kit.

Interesting idea though, but you’d end up having to bundle it with DBaaS, at which point you’ve got the pressure and stress of having to look after everyone else’s data.

It’s really not worth doing this because the back and forth latency of SQL is much worse than proxying a HTTP/RPC request to the app server sitting next to the DB and getting the final result back.
