Console Variables in gremlin remote console.

[Shahid Iqbal]

Hi,

I am newbie and using Gremlin Console connecting to AWS Neptune from an EC2 instance and having few questions if someone can guide.

1. I want to use variables within Gremlin Console with approach as below, but it's not working. How can I get this working? Please see error at the end of message.

Second, any reference you can suggest for:

- Graph Schema Modeling  (basically guidelines to model a NoSQL DB or Relational DB to Graph DB)

Third, Can you please suggest an add-on or API that can create Visual Graph either from a Gremlin Query output or from JSON output of a Gremlin query.

Many thanks.

Neptune is sessionless therefore it can't support that capability in the console. See other differences here:

https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-differences.html

As for references for "graph schema", i'm not sure. I've always found that kind of documentation really hard to write myself and i'm not sure i can think of any resources that are especially helpful....I don't think Kelvin's book even covers that:

http://kelvinlawrence.net/book/Gremlin-Graph-Guide.html

Gephi works pretty well for visualization with Gremlin:

http://tinkerpop.apache.org/docs/current/reference/#gephi-plugin

you do have to work a bit differently than that tutorial if you're trying to work with neptune though. you would need to subgraph() 

http://tinkerpop.apache.org/docs/current/reference/#subgraph-step

neptune and then visualize that subgraph or some query of that subgraph.

Yes, I only scratch the surface on data modelling in the book. It's a topic I should probably consider adding more coverage on but I do provide a little guidance on a few basic things to consider when designing a graph schema but that's about it.

The small amount of coverage I do have is in these two sections:

http://www.kelvinlawrence.net/book/Gremlin-Graph-Guide.html#gremlinandsql

http://www.kelvinlawrence.net/book/Gremlin-Graph-Guide.html#dmodel

Cheers,

Kelvin

As you mention Gephi as a vizu tools for Gremlin, maybe you can help me to well configure my env (I already do a post about my issue "tinkerpop.gephi plugin always 404"

I read the documentation many times, maybe I do a mistake.

My 3.3.3 console sequence:

gremlin> :plugin use tinkerpop.gephi
==>tinkerpop.gephi activated
gremlin> graph = TinkerFactory.createModern()
==>tinkergraph[vertices:6 edges:6]
gremlin> :remote connect tinkerpop.gephi
==>Connection to Gephi - http://localhost:8080/workspace1 with stepDelay:1000, startRGBColor:[0.0, 1.0, 0.5], colorToFade:g, colorFadeRate:0.7, startSize:10.0,sizeDecrementRate:0.33
gremlin> :remote config host 192.168.56.1
==>Connection to Gephi - http://192.168.56.1:8080/workspace1 with stepDelay:1000, startRGBColor:[0.0, 1.0, 0.5], colorToFade:g, colorFadeRate:0.7, startSize:10.0,sizeDecrementRate:0.33
gremlin> :remote config port 8081
==>Connection to Gephi - http://192.168.56.1:8081/workspace1 with stepDelay:1000, startRGBColor:[0.0, 1.0, 0.5], colorToFade:g, colorFadeRate:0.7, startSize:10.0,sizeDecrementRate:0.33

Gephi 0.9.2 side, the streaming plugin parameters are:

Port 8081, no SSL, no basic authent.

The embedded jetty seems to be OK, so no network problem, but the only response I receive is 404.

gremlin> :> graph
Unsuccessful request to Gephi - [404] Not Found - <html>

Even in a browser, no matter the URL: http://localhost:8081, http://localhost:8081/workspace1, http://192.168.56.1:8081/workspace1...

?
