@farodin91 I will try to review it this week

[farodin91]

@farodin91 I didn't review this PR yet but I see that Travis CI fails and Codacy has a lot of issues. I think that should be fixed.

I don't want to fix all codacy issue to prevent any major changes.

I don't want to fix all codacy issue to prevent any major changes

That is OK but I think at least CI build should pass

@porunov I did break something by rebasing.

Finally I have reviewed all the code in this PR. All code LGTM. Thank you for moving it to janusgraph-driver, also thank you for some additional refactoring.
Even so it looks like everything should work, I would like to execute TinkerPop tests for all big PRs.
I've started TP tests for current master branch with merged this PR into it. I will post a result in about 15 hours.

[porunov]

LGTM. Thank you @farodin91 .
All TP tests passed.
