Hi, I'm looking for a graph-friendly DB that can sync well between many types of client (desktop, mobile) and server, similar to CouchDB/PouchDB. I found [1] below that seems relating but no further discussion. Could you give some more information about that? Thanks, and congrats on the new funding!!

  I think Dgraph is not a great choice for this right now, as it seems you're looking to be able to use those different replicas offline too? We use RAFT to reach consensus on transactions, so the nodes need to be able to communicate with each other. I'm definitely adding this as a feature request though, I would love to chat with you more about your requirements if you're interested (francesc@dgraph.io). Also, have you considered CRDTs?

    Thanks for your confirmation, and addition for a feature request (sorry for a bit late response). So, it will be more practical that I rethink my requirements first. Will send you email if there is further question!

I work with hypergraphs, where edges have an arbitrary number of nodes. I'm quickly looking through your documentation, Discuss, and GitHub issues/roadmap to try and find out if edges may have more than two nodes. This has been asked about already: https://github.com/dgraph-io/dgraph/issues/1#issuecomment-404801622 https://github.com/dgraph-io/dgraph/issues/1#issuecomment-40... While we have your attention on HN, could you comment? (Sorry if I missed this information elsewhere.) Thank you!

  in what scenario would you need an edge with two nodes rather than just making a node to represent the connection

  (Dgraph founder here) Dgraph's edges only have two nodes, sorry.

  Hi Richard, What applications/problems are you solving using hypergraphs? There is definitely a dearth of high performance hypergraph processing engines/systems.
