      Description

      The DSL query 'mytype where property.id = "id1"' appears to be rewritten as a gremlin query that resembles:

      g.V.has(typename, 'mytype'ยจ).as.out('property').has('id', 'id1').back('x')

      On our system this query takes 6-7 minutes. The query

      g.V.has('id', 'id1').in('property').has('typename', 'mytype')

      takes 350 milliseconds.

      Our graph:
      g.V.count() = 1359151

      We have atlas 0.7 installed. I've compiled the latest 0.9 code and looked at the generated gremlin query as reported in the logs for the same DSL-query, and I think 0.9 has the same performance issues. Unfortunately I don't have a big graph on a 0.9 installation to test performance.
