Graph queries for a social feed

We’re building a platform with a social feed. Not a timeline of photos or opinions – a feed of plans. Things people intend to do. The interesting question isn’t “what did my friend share” but “what is my friend’s friend doing this Saturday, and can I join.”

That second question – friend-of-friend discovery – is what made me reach for a graph database.

Why graph

At first glance, a feed is just a list. The interesting part is underneath – a web of relationships: who knows whom, who created what, who joined what.
