Github user okram commented on the pull request: https://github.com/apache/incubator-tinkerpop/pull/316#issuecomment-220440890 These are "master traversal" traversers. Even before when it was stored in sideeffects, those are ultimately stored in `Configuration` (`TRAVERSAL`). Its the same scalability as before, just better semantics as we shouldn't store halted traversers as side-effects (they have "left the traversal"). Finally, since the beginning, OLAP reductions to the master traversal are only as scalable as the single machine it comes back to. Thus, groups(), limits(), groupCounts(), sums(), etc. are important. There is no `g.V()` on a billion vertex graph and stream back results.
