Hi everyone,

I'm pleased to announce G.V() (pronounced gee dot vee), a new IDE to support your every day Gremlin work. 
G.V() is a software executable for Windows, Mac and Linux that allows you to write and execute gremlin queries against any hosted Gremlin Server technology that implements Apache Tinkerpop 3.4.0 or above.

In short, it does (and allows doing) the following:
- Create connection configurations to your gremlin server(s)
- Write, execute, save Gremlin queries against your gremlin server(s)
- Visualise your database's data model
- Auto complete of your queries as you write them
- Visualise the output of your gremlin queries in various formats (graph, plain text, table)
- Implements the Tinkergraph functionality to allow you to create in-memory graphs from scratch or against existing data, for learning and experimenting purposes.

It's free to download and use, no details required. You can get it now or learn more about it at https://gdotv.com.

As this is a beta version feedback is crucial and will help turning G.V() into a solution that fits the needs of the Apache Tinkerpop community.
Please feel free to provide feedback below, or to feed...@gdotv.com
If you run into any bugs, please feel free to get in touch too. 
Alternatively a survey is available from within the software itself.

Hi Arthur,

Very promising!
Will it be opensourced in the futur? Could it be embedded in a web navigator like VisualStudio / Theia?

Hi Nicolas,

G.V() shares an awful lot in common as far as architecture/design with VSCode/Theia (ElectronJS is the common software development framework). The entire user interface is web-based already, so from a design perspective it's already 90% ready to embed in a browser. 
The main barrier to integrating to VSCode/Theia I can see at the moment is that G.V()'s "backend" is written in Java to match Apache TinkerPop's technology stack as closely as possible. 
It's likely to be quite impractical for integration with other tools. However there are components of G.V() that could definitely make it into those two, particularly the "Query Language Service" (the bit that allows writing queries, getting auto complete suggestions, and offering syntax error detection) and possibly the "Data Model Visualisation Service"  (the bit that loads known vertices/edges/properties and their structure to display and use within the "Query Language Service").
At the moment I don't plan to have these integrated in these tools; however I do plan to swap out the "CodeMirror" query editor with Monaco (VSCode's awesome code editor) so the look and feel will certainly converge to that. 
Regarding the future of the tool, it's unclear at the moment. 
My main priority is to make something useful for Gremlin users and attractive to those that are considering working with graph databases and perhaps trying to decide between different technologies or considering migrating to Gremlin. To allow this to happen G.V() will need to be free to at least some degree. Which of an open source or commercial model will allow it to get achieve that and more, I don't know. For now I hope that it's useful and fit for purposes - there's a lot of features I intend to add to it.

Can't actually connect to AWS Neptune, getting: 

Failed to connect: All hosts are considered unavailable due to previous exceptions. Check the error log to find the actual reason.

With no link/direction to the error log ¯\_(ツ)_/¯

This looks like a networking issue.  Do you get a response if you curl https://<your endpoint>:8182/status?

I usually use wss, not https (from gremlin-python). for https I got {"code":"AccessDeniedException","detailedMessage":"Missing Authentication Token"}

Hi Shay,

Are you tunnelling through to your AWS VPC hosting your Amazon Neptune instance before connecting to it via G.V()? The error message you've received indicates that the host is not known or reachable, which suggests as David pointed out a networking issue. 
To get your local machine connected to your Neptune instance, I'd suggest following the steps described at https://github.com/aws/graph-notebook/tree/main/additional-databases/neptune for SSH tunnelling. 
Alternatively, you can stand up a Windows/Ubuntu virtual machine in the same VPC as your Neptune instance, allow traffic on port 8182 of your instance from your VM and run G.V() from there. 
Though SSH tunnelling is the most convenient option.
Let me know how that works.

I am not. I'm connecting using AWS credentials from my dev env (IAM) with the https://github.com/awslabs/amazon-neptune-tools/tree/master/neptune-python-utils lib. Any change for IAM DB authentication support? https://docs.aws.amazon.com/neptune/latest/userguide/iam-auth.html

G.V() doesn't support AWS IAM authentication just yet, though it looks quite straight forward to implement based on those docs. I'll see about building that in the next week or two, if you're okay to stay tuned for it. In the meantime your only option would be to authenticate the legacy way to your Neptune cluster.

I'll wait. But it it was open-source, I'd probably implement it for y'all. Worth considering open-sourcing it. Might help with the Linux image size as well - 250MB is WAYYY too big

Because G.V() comes with a bundled JRE it's a bit bulky, though it does save users needing to download and install it beforehand or worry about having the right version. That being said it can be heavily shrunk with jlink/jrelease.  Optimizing build size is definitely feasible, haven't got round to implementing it :D
