I've yet to go beyond a cursory skim of graphql - but my first impression is that in the end you get to write your very own query planner/optimizer - with the "benefit" of optimizing across wildly different data stores like unifying a few different sql databases, a few filsystem graph/hierarchies of meta-data and a handful of semi-structured document stores in the form of json/soap services... So a lot harder than the already pretty hard problem of writing a query planner for "just" an rdms.

But I think there's something "there" - graph dbs, datomic, web prolog - they all seem to point to clients asking a "what" with the server figuring out the "how" [ed: and not in the least: whence (from where)] .
