It is not clear how to make collaborative filtering example for many users

[lfomendes]

The collaborative filtering example is good, but for a real app, we would have to make millions of requests, spending a lof of time going from app to Neptune. How can we change this example for many users in a single query?

g.V().has('GamerAlias','skywalker123')

How can we make a query that get the topN for many users, not only for skywalker123?
