Ask HN: How relevant are graph databases/technologies today?

At Pinterest we have a graph db developed internally called Zen. If you just search on google you’ll find a lot of docs and presentations. It’s used all over the places, if you search in our engineering blog you’ll see it mentioned constantly.

In terms of applications using graph, my favorite one is our recommendation engine: https://medium.com/pinterest-engineering/an-update-on-pixie-...

Another very interesting (and very recent) application of graphs in security is Cartography by Lyft: https://github.com/lyft/cartography

(I’m on the go, please excuse the lack of links for Zen)
