             Summary: Remove GroupCountStep in favor of new Reduce-based GroupStep
                 Key: TINKERPOP3-872
                 URL: https://issues.apache.org/jira/browse/TINKERPOP3-872
             Project: TinkerPop 3
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.0.1-incubating
            Reporter: Marko A. Rodriguez
            Assignee: Marko A. Rodriguez


Check it. In the {{group_step_2/}} branch, we can now do this efficiently as we now support "on the fly" reduction.

{code}
gremlin> g.V().both().both().group().by('name').by(count())
==>[ripple:3, peter:3, vadas:3, josh:7, lop:7, marko:7]
gremlin> g.V().both().both().groupCount().by('name')
==>[ripple:3, peter:3, vadas:3, josh:7, lop:7, marko:7]
{code}

Now, stand back... 

{code}
gremlin> clock(1000){g.V().both().both().group().by('name').by(count())}
==>0.008825609
gremlin> clock(1000){g.V().both().both().groupCount().by('name')}
==>0.0051918749999999994
{code}

Speed differences are reasonable and I know various places in the new {{GroupStep}} that I can optimize to make more efficient.

And that is how the dishes get done.
