True, but there's no way to avoid people interpreting NoSQL as a relational database alternative. To your point regarding Google's F1, try looking at Impala (h

  It's quite interesting to compare the two approaches, thanks for the tip. I mentioned it not because of the SQL but because of its unusual construction: it's a relational database stored on top of a (admittedly ACID) NoSQL (it actually does have a sql engine) key-value store: it's a full-blown relational database system where you don't have to worry about sharding. I think Impala also has a great approach to this, but I'd say it's far more similar to Dremel in that it's structurally still Key-Value. This, again, could be good or bad: probably easier to develop with but harder for the query planner to plan without the hints provided by a table-and-index based system. (i.e. possible—that would basically be F1—but you'd have to do it by hand).
