[jira] [Created] (ATLAS-1369) Optimize Gremlin created for DSL Translation

Jeffrey Hagelberg created ATLAS-1369:
----------------------------------------

             Summary: Optimize Gremlin created for DSL Translation
                 Key: ATLAS-1369
                 URL: https://issues.apache.org/jira/browse/ATLAS-1369
             Project: Atlas
          Issue Type: Improvement
            Reporter: Jeffrey Hagelberg
            Assignee: Jeffrey Hagelberg


The way the queries are generated now, in many cases the indices are not used when executing queries.  The main problem is that gremlin cannot currently use "has" expressions within an "and" or an "or".  This JIRA introduces a GremlinQueryOptimizer that attempts to extract "has" expressions out of "and" expressions and turn "or" expressions into unions.
