My ideal version of this is simple: just define the queries you want (no matter how complex) and the you'll get exactly the data you need to fulfill those queries, no more, no less. And the cherry on top would be to have your queries update automatically with changes both locally and remote in close to real-time.
That's basically what we're doing with Triplit (https://triplit.dev), be it, not with SQL--which is a plus for most developers.
