I understood Hasura is planning to support other databases to like Mongo and/or MySQL. If you run Hasura with something like AWS RDS most of your scaling issue on the data side is resolved. You can still run multiple instances of Hasura itself to horizontally scale it. Have to admit I haven't had this issue yet and I think it's a nice problem to have at that time as means too many paying customers :)
