[jira] [Created] (ATLAS-2520) Use JanusGraph traversal over gremlin script

Apoorv Naik created ATLAS-2520:
----------------------------------

             Summary: Use JanusGraph traversal over gremlin script 
                 Key: ATLAS-2520
                 URL: https://issues.apache.org/jira/browse/ATLAS-2520
             Project: Atlas
          Issue Type: Improvement
    Affects Versions: 1.0.0-alpha
            Reporter: Apoorv Naik
            Assignee: Apoorv Naik


Currently lot of code in Atlas follow a concept of GremlinQueryProvider which gives TP2 and TP3 queries depending on the graph backend being used. Since Atlas 1.0 is primarily going to rely on JanusGraph, it makes a more sense to remove TP2 related queries/abstractions and use the GraphTraversal Java API provided by JanusGraph.

 

PRO: Lot of unused code can be removed, more expressive Graph querying/traversal.

CONS: Decommissioning TP2 completely is a major engineering effort
