Gremlin: adding edges between nodes having the same property

Question

I am very new to Gremlin. I am trying to build a graph on DSE graph using Gremlin. I am able to create the vertices:

a = graph.addVertex(label, \'label1\',          


        

Answer 1

Nested g.V()'s are usually a bad idea. You can solve the problem using a single traversal:

g.V().hasLabel("label1").as("a").
  V().hasLabel("label2").as("b").
  where("a", eq("b")).by("key").
  addE("link").from("a").to("b")

Also note that you'll have to allow scans in DSE Graph to make this traversal work.
