---------------------------------------------

             Summary: OrderGlobalStep should use local star graph to compute sorts, prior to reduction.
                 Key: TINKERPOP-1248
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1248
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.2.0-incubating
            Reporter: Marko A. Rodriguez


We can get local star graph expressivity from `OrderGlobalStep` in OLAP if we emit the object + its `by()`-modulated values. It will yield more data in the order, but it will reduce the CPU time as we don't have to call `by()` on each order check.

This ticket will be a bit involved as it will depart from `CollectingBarrierStep` semantics and thus, complicate `OrderGlobalSteps` implementation...
