Graph DB technology has been advancing fast over the last few years, and more evolutions are coming down the pipe. For example, Titan and Blazegraph are distributed and can handle billions of edges, and Blazegraph can be GPU-accelerated, which "demonstrated a throughput of 32 Billion Traversed Edges Per Second (32 GTEPS), traversing a scale-free graph of 4.3 billion directed edges in 0.15 seconds" (https://www.blazegraph.com/product/gpu-accelerated/).
NB: TinkePop is not a graph DB -- it's a graph software stack / computing framework for graph DBs (OLTP) and graph analytic systems (OLAP). Since TinkerPop is integrated with almost all of the graph DBs and graph processing engines, its mailing lists are good place to discuss and get help with graph-related projects.
I like how at least the BlazeGraph people are talking about billions of edges and not thousands, but I'm not sure that's something I could use. That seems to be a "pre-order" page, so it sounds neither open source nor existent. And I'm trying to figure out what their normal non-GPU non-distributed software is, but it seems to mostly be a pile of Javadocs.
Using distributed computing on mere gigabytes of data is silly.
I think TinkerPop was something else back in 2011, but apologies if I've used the wrong terminology.
