Brain Zambrano presented recently at ☞ MongoSV the way Eventbrite is using MongoDB for modeling their user/events social graph.
Slides can be downloaded from ☞ here.
Now the slides are really interesting and provide a lot of details both about the setup and the implementation details. But if you check slides 19 to 22 you’ll see why I’m saying that graph databases should be used for any graph problem that involves more than 1-level navigation.
Twitter has built their own ☞ simpler graph database, ☞ FlockDB, but as stated in the docs: “multi-hop queries (or graph-walking queries) are a non-goal”.
