This was my thought exactly with the TinkerPop3 release. Looks like, to move this forward, we’d need to implement gremlin-core per <http://www.tinkerpop.com/docs/3.0.0.M1/#_implementing_gremlin_core>. The real question lies in whether GraphX can only support the OLTP functionality, or if we can bake into it the OLAP requirements as well. At a first glance I believe we could create an entire OLAP system. If so, I believe we could do this in a set of parallel subtasks, those being the implementation of each of the individual API’s (Structure, Process, and, if OLAP, GraphComputer) necessary for gremlin-core. Thoughts?

The whole Tinkerpop2 Gremlin design was based around streaming pipes of data, rather then large distributed map-reduce operations. I had to hack the pipes to aggregate all of the data and pass a single object wrapping the GraphX RDDs down the pipes in a single go, rather then streaming it element by element. Just based on their description, Tinkerpop3 may be more amenable to the Spark platform.

It has MapReduce to run Gremlin operators in a distributed manner and Giraph to execute vertex programs. The Tinkpop3 is better suited for GraphX.

I've also implemented portions of the Gremlin Search Language and a Parquet based graph store. I've been working out finalize some code details and putting together better code examples and documentation before I started telling people about it. But if you want to start looking at the code, I can answer any questions you have. And if you would like to contribute, I would really appreciate the help.
