ASF GitHub Bot commented on TINKERPOP-1490: ------------------------------------------- Github user davebshow commented on the issue: https://github.com/apache/tinkerpop/pull/478 @aholmberg I'm not sure if I follow...it seems to me that if a `RemoteConnection` implementation returns a list (or future list ) of `FutureTraversers`, the traversal API can still remain independent from the transport. Even if the GLV needs to operate on the Traversers, `asyncio.Future`, `concurrent.Future`, and `tornado.concurrent.Future` have compatible APIs (`done`, `cancel`, `add_done_callback`, `result`, `set_result`, `etc.`). The "specialized" handling of the future, whether it be a coroutine that requires a `yield`, `yield from`, or `await` expression, or a `concurrent.Future`, will in the end be handled by application code written by the end user. > 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} > ... -- This message was sent by Atlassian JIRA (v6.3.4#6332)
