At this point I really have to wonder how many people have written graph engines on top of lmdb! In the past month I've seen two from the same bank built on top of lmdbjava. Instead of reinventing this same wheel over and over it'd probably make sense for somebody to sitdown with lmdb and tinkerpop [1] and bang out one decent implementation.<p>...actually this has been done [2] but the project looks abandoned. So NSA guys you should get right on this.<p>[1] <a href="http://tinkerpop.apache.org/docs/current/reference/" rel="nofollow">http://tinkerpop.apache.org/docs/current/reference/</a><p>[2] <a href="https://github.com/pietermartin/thundergraph" rel="nofollow">https://github.com/pietermartin/thundergraph</a>
for laymen like me: what is this, and what are the perfect use-cases for this?<p>"..log-based transactional graph (nodes/edges/properties).. ..primary use case is to support streaming seed set expansion." -- I'm totally lost.<p>I know these kind of software is targeted at developers, but it won't hurt to give analogy like "Uber for XXX" like in startup pitches. e.g. "It's like <put popular product name here e.g. MySQL> but <differentiating factors>".
