Re: [BLOG] Configuring JanusGraph for spark-yarn

Hi Joseph, You ran into terrain I have not yet covered myself. Up till now I have been using the graben1437 PR for Titan and for OLAP I adopted a poor man's approach where node id's are distributed

Re: [BLOG] Configuring JanusGraph for spark-yarn

Hi Marc - I've been able to get it to run longer, but am now getting a RowTooBigException from HBase. How does JanusGraph store data in HBase? The current max size of a row in 1GByte,

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: https://github.com/PlatformLab/ldbc-snb-impls converted all the embedded Gremlin to strings.

Re: Do We Need Specialized Graph Databases? Benchmarking Real-Time Social Networking Applications

This blew up a while ago on the Twitter last month https://twitter.com/adriancolyer/status/883226836561518594 The testing set up was less than ideal for Titan. Cassandra isn't really meant for a

Re: How can I load the GraphSON(JSON) to JanusGraph and how about update,delete vertices and edges?

That is an outdated version of TinkerPop and GraphSON as stated on that page. Use this current reference http://tinkerpop.apache.org/docs/current/reference/#graphson-reader-writer Robert Dale

Re: Problem downloading JanusGraph as a maven artifact.

That dependency isn't found in Maven central, jbcrypt-0.4 is found in the jitpack.io repository. You'll need to add a remote repository for it. If you're using the Gremlin Console, you can use the

Re: Best practice setup for Go driver development & identifying the websocket serialization format

That makes sense to me. Is there a suggested way to format data in the `data` section. I realise you can write a script to output anything you wish, but if I'm, say, wanting to do CRUD style work on a

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.

Re: Best practice setup for Go driver development & identifying the websocket serialization format

Do you have a reference for that setting the response format? The driver documentation doesn't mention it, only that you can specify the format of the request. There is an example response in JSON,

Re: Best practice setup for Go driver development & identifying the websocket serialization format

The server serializes the response in whichever format has been requested by the client. I'd imagine what you're seeing would be the unmarshalled version of the returned JSON that your go websockets

Best practice setup for Go driver development & identifying the websocket serialization format

I want to develop a driver in Go that connects to Gremlin Server using a websocket, runs a parameterized Groovy script and parses the response. At this stage all I need to do is perform basic queries
