This does that. There's nothing saying that individual query elements have to hit the database directly. Besides authz (which others have mentioned), you have the potential for various caching strategies as well as letting the backend make cost decisions in general about where to get things. It could be that you mostly pass through to a Datomic. It could also be that each element hits a different microservice. The point is that your client doesn't know this or care.
