             Summary: Provider a Future based Traversal.async(Function<Traversal,V>) terminal step
                 Key: TINKERPOP-1490
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1490
             Project: TinkerPop
          Issue Type: Improvement
          Components: language-variant, process
    Affects Versions: 3.2.2
            Reporter: Marko A. Rodriguez


[~mbroecheler] had the idea of adding a {{Traversal.async()}} method. This is important for not only avoiding thread locking on a query in Gremlin, but also, it will allow single threaded language variants like Gremlin-JavaScript to use callbacks for processing query results.

{code}
Future<List<String>> result = g.V().out().values("name").async(Traversal::toList)
{code}

{code}
Future<List<String>> result = g.V().out().name.async{it.toList()}
{code}

{code}
g.V().out().values('name').async((err,names) => {
  // I don't know JavaScript, but ...
  return list(names);
}) 
{code}

...
