             Summary: DSL - Fix back reference DSL to gremlin translation issues
                 Key: ATLAS-145
                 URL: https://issues.apache.org/jira/browse/ATLAS-145
             Project: Atlas
          Issue Type: Bug
            Reporter: Suma Shivaprasad


GremlinQuery.scala

/*
     * TODO
     * Translation Issues:
     * 1. back references in filters. For e.g. testBackreference: 'DB as db Table where (db.name = "Reporting")'
     *    this is translated to:
     * g.V.has("typeName","DB").as("db").in("Table.db").and(_().back("db").has("name", T.eq, "Reporting")).map().toList()
     * But the '_().back("db") within the and is ignored, the has condition is applied on the current element.
     * The solution is to to do predicate pushdown and apply the filter immediately on top of the referred Expression.
