I have an Amazon EC2 (windows) and an Amazon Neptune, both in the same VPC. I would like to connect to Neptune from EC2 using either sparql or Gremlin and don't know how to do this. I found

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

and

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

None of the two explains how to call Neptune using sparql or Gremlin (is it from terminal or do they have studios of their own?) Thanks for any hint.

I imagine you would use something like the Gremlin Console to connect to your Neptune instance. I think the documentation is pretty good: http://tinkerpop.apache.org/docs/3.3.3/tutorials/getting-started/#_the_first_five_minutes

Unzip the console from the downloaded file and then just run bin/gremlin.bat (on Windows).

Thank you. I was able to switch to linux instance and use the page you recommended.

The documentation for how to connect to Neptune from EC2 using the Gremlin Console is located here [1]. You can also connect from EC2 using a program written in a language like Java. You will find additional links to samples of how to do that in the docs linked below also.

[1] https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-console.html

You can run the Gremlin Console from your EC2 instance in a basic terminal/command window.

If you prefer a more IDE/GUI approach you can also connect to Neptune from Cloud9

Hope this helps, Kelvin
