Allow bulk edge creation to include addition key/value pairs

I took a pass at #300 (rather then just constantly opening tickets, right? ;) ). I couldn't get local builds running so I don't know for sure if the test works or not. I tried sticking to style but I never know what Eclipse is doing so feel free to suggest changes if necessary.

Thanks for the PR, I'll have a look at it later.
Why can you not get the local build to work? Errors?

There were compilation problems with the test project, it looked like it was unable to find Groovy. I didn't have Maven installed so I grabbed the latest (3.5.4). The test project also had problems in Eclipse, though I think that may have just been missing Groovy m2e extensions (aside from Gradle I don't have much experience with developing Groovy).

Also, I wasn't sure which databases I needed to have created: it would nice to have a Docker image that spins up the database ready for testing, I'm very busy right now, but I could put it on "the list" if I knew where to look for the expected initial state of Postgres.

Just discovered the .travis.yml, that should have everything I need, let me give it a try...

I found a few cycles :) See #302 for how I got a Postgres instance up for testing. Still didn't see the tests run through on that PR branch though.

I could not get Travis to work for Sqlg. The environment is too complex for Travis and needs too much memory.
Using Teamcity now running on

Not sure why your project did not build. mvn clean install -DskipTests is suppose to work.

Under the sqlg-test there is a file tp3.databases that indicates all the TinkerPop databases needed.
For Sqlg's own tests it is just sqlgraphdb

To run the full test suite is too intense. Need all the supported databases and it takes forever.
I'd suggest jut running PostgresAnyTest to test your PR specifically and PostgresAllTest to check something else did not break.

And ideally run SqlgPostgresStructureStandardTest and SqlgPostgresProcessStandardTest also as it will run TinkerPop's test suite. For this you will need to create all the TinkerPop databases.

A tad busy with the day job, should get round to checking the PR on the weekend.
