Ask HN: Anyone use graph db in production/at scale? Like Neo4j or Arangodb?

Please share any experiences. I'm specifically evaluating Neo4j and my sandbox testing is going well so far but I'm curious to hear from people who have far more experience.

FWIW I have a graph use case implemented with pg where I'm running into issues with recursive queries, whereas the neo4j queries are far better performant and easier to reason.
