Re: [BLOG] Configuring JanusGraph for spark-yarn
Hi Joseph,

Re: Best practice setup for Go driver development & identifying the websocket serialization format
I don't think that you have a serialization problem here, but more of an idiosyncrasy of how gremgo works. I've used it a bit, and whenever gremgo returns a value, it returns it using an empty

Index on a vertex label from Java
How does one create an index on a vertex label from Java? I want to speed up queries that retrieve or count the vertices with a particular label, e.g. g.V().hasLabel("foo").count().next(). In

Re: Do We Need Specialized Graph Databases? Benchmarking Real-Time Social Networking Applications
It did use parameters. They basically forked Jonathan Ellithorpe's work:

converted all the embedded Gremlin to strings.

Re: Best practice setup for Go driver development & identifying the websocket serialization format
What you're receiving looks a lot like the `data` section of the response JSON. Not knowing what client you're using, I can't say that's normal behaviour, but I've seen http clients behave similarly.
