Re: [TinkerPop] A 2D Gremlin Language Variant

[Marko Rodriguez]

Hi,

I was thinking about your tensor notation desire.

[created]x[knows]^ 

is equivalent to:

V().out(‘created’).in(‘knows’)

In general, we could do stuff like in this article:

https://arxiv.org/abs/0806.2274 

We just map all the presented algebraic operations over to a syntax that can 
then be compiled to Gremlin bytecode.

Hi,

Check it out:

https://gist.github.com/okram/c9e7dc6e51fcf067b9d77c6c4ea094da 


The code is pretty dead simple:


https://github.com/apache/tinkerpop/blob/9b15e90a651383bc7ab0c014f1492bbf70bc3848/tinkergraph-gremlin/src/test/java/org/apache/tinkerpop/gremlin/tinkergraph/g2/g2Parser.java
 


Right now I’m manually testing using text files on my Desktop. However, you can 
see how easy it is to interact with the parser.

All good here, `docker/build.sh -t -i -n` succeeded 2 times in a row for me.

Been having problems with traversal interrupted tests failing across many 
branches but I ran other tests including neo4j and everything passed.  Checked 
out match retraction updates and they look good.

I remember that we talked about that, but I thought we'd said this version 
was ok

```text
$ docker --version
Docker version 1.12.3, build 6b644ec
```

no?

I retested again overnight after rebasing the PR on `tp31` and still having 
success with Docker build on Ubuntu and Mac. Looking at the code changes, I 
don't see how they would cause that Spark failure.
