Neo4j Workshop

Seattle, it's time to refresh our enthusiasm for graph-like thinking with a hands-on workshop.

 

What do you think about having a progressive koan programming challenge, either focusing on Cypher or Java coding? We'll provide sample data sets that demonstrate different modeling approaches, and the consequent queries. 

 

Note that the Date is really just proposed, and we'll need to pick a host location. Please chime in on the comment thread with any thoughts about the topic, time and place. 

 

Cheers,

Andreas

    Very informative!

    I think a loose agenda could have made the meetup a bit more focused (too much driven by random questions).

    The solution I came up with works for my case I think. I kind of moved on to the next problem. If there's a shortage of things to talk about, I'd love to discuss, but it seems that there will be no shortage of topics, so let's play it by ear tonight :-)

    @Eelco On a project dealing with DNS records we wanted to deal with historical data on relationships. For instance last month the A record may have pointed to a different set of IPs than this month. We handled this by placing the fetch date as a property on the directed edge from the domain name to the artifacts of that record type. We could then say in our traversal, follow all "A" edges where the date is greater than X days, or is the most recent, etc. That worked well for us!

    @John: both. Here is a sketch of the solution I have implemented now: http://screencast.com/t/DikASCq...­. We'll discuss at the meetup if we get to it :-)

    Andreas, as I mentioned to you I'm starting an experimental effort to build out a graph database around theme park routes, there are 2 aspects of this problem, one is how to create these nice looking open-street like interface and tying this into a machine learning component that has a real time and an async aspect to it. I'd also like to talk through some design ideas around neo4j-mahout sometime during this workshop.

    Eelco,
    One idea is to store the old copies of the graph in a big table like database so that you can perform analytics on that data, additionally you can have a real time component like solr offer you a services API around the old graphs, you then would need to figure out how to map out keys identify the graphs from solr. We can talk more about this on a whiteboard during the workshop.

    Sweet, I'm going to be in town! See y'all there.

    I'd love for this to be about Cypher and even Gremlin, and about different ways of modeling, *not* about Java. =)

    I'm using Neo4J as the storage for a back-end system we're building, and the thing I'm currently exploring is how to deal with historical data. I have a few ideas how to map my regular graph to one that would support getting the state at any given (other) time, but would love to bounce these ideas to Neo4J peers if anyone is interested :-) Might be a fun thing to spend 20 mins on or so if we have a white board in the room?

    I'd like this to be a hands on workshop where we for example could tackle solving a few interesting problems , do folks have particular areas of interest, mine is tying together machine learning and graph databases

    I'm all for a focus on Cypher and how to optimize your model for the types of queries your application requires.
