Fix Version/s: 3.2.2
> RemoteConnection needs to provide TraversalSideEffects.
> -------------------------------------------------------

> Key: TINKERPOP-1347
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1347
> Project: TinkerPop
> Issue Type: Improvement
> Components: driver, process, server
> Affects Versions: 3.2.0-incubating
> Reporter: Marko A. Rodriguez
> Assignee: stephen mallette
> Labels: breaking
> Fix For: 3.2.2
>
>
> Right now the {{RemoteConnection}} API is this:
> {code}
> public <E> Iterator<Traverser.Admin<E>> submit(final Traversal<?, E>
> traversal) throws RemoteConnectionException;
> {code}
> This is bad because a result set is not just an iterator of traversers, it is
> also the sideEffects. I just hit a big snag in {{gremlin-variants}} when not
> using TinkerGraph and thus, not everything in the same JVM.
> I think we should do one of two things:
> {code}
> public <E> Traversal<?,E> submit(final Traversal<?, E> traversal) throws
> RemoteConnectionException;
> {code}
> In essence, a traversal goes out an then a traversal comes back and that
> traversal has an end step iterator of traversers as well as traversal
> side-effects. Moreover, that returned {{Traversal}} could be like
> {{RemoteTraversal}} and when {{getSideEffects()}} is called, the sideEffects
> are lazily fetched ....
> We will have the same problem when we extend {{RemoteConnection}} with:
> {code}
> public <E> Iterator<Traverser.Admin<E>> submit(final String alias, final
> String scriptEngine, final String traversalScript, Object... bindings) throws
> RemoteConnectionException;
> {code}
> I sort of like the concept of {{RemoteTraversal}} as it allows us to not only
> {{getSideEffects()}}, but also {{toString()}}, etc. A remote traversal can
> offer more control than just {{Iterator}}.
