Jorge Bay commented on TINKERPOP-1490: -------------------------------------- {{async}} is a reserved keyword in many languages: - In C# 5+ and above. - In [Ecmascript|https://tc39.github.io/ecmascript-asyncawait/], already [implemented in some of the Javascript runtimes like Microsoft Chakra|https://blogs.windows.com/msedgedev/2015/09/30/asynchronous-code-gets-easier-with-es2016-async-function-support-in-chakra-and-microsoft-edge/#Ld5l0SCaX4soGX2p.97]. - It looks like it's also going to be a [reserved keyword in Python 3.7|https://www.python.org/dev/peps/pep-0530/]. Maybe something like {{toListAsync()}}, as async counterpart of {{toList()}}, and {{getAsync()}}, as a counterpart of {{next()}} (instead of {{nextAsync()}} to avoid to give the impression that is an "async iterator") ? > 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)
