Gremlin needs vertex centric index for such kind of queries it is in our roadmap but is not implemented yet. > Am I right in assuming something like > pipe.start(root).out("link_to_test").has("testId",123) > can't be represented using the VertexQuery api ?

Yes you are right. > Are there any performance advantages/disadvantages to using the > VertexQuery or gremlin api as opposed to the SQL api ? Usually SQL queries are faster because they use database internal features. > If I create a compound index, is there anyway to query over that compound > index using the gremlin api ? You should use SQL in such case, gremlin does not have such kind of index in it's model.
