----------------------------------------------------------------
I need to dig into the TinkerPop API. I think implementing Gremlin would be the
desired end game.
I see a distributed Gremlin implementation as another Parallel Computing
problem, like the Parallel SQL interface. This is where the Streaming API comes
in. If we can model graph traversals with the Streaming API then we can have a
Gremlin parser that compiles to Streaming API objects. This was the approach
taken with the SQL interface.
So this ticket is really about laying the Parallel Computing framework for
supporting graph traversals.
I do agree that looking at TinkerPop will be very useful in understanding what
to model.

> Assignee: Joel Bernstein
> Labels: Graph
> Fix For: Trunk

>
> I think it would be useful to model a few *distributed graph traversal* use
> cases with Solr's *Streaming Expression* language. This ticket will explore
> different approaches with a goal of implementing two or three common graph
> traversal use cases.
