Multiple DB support for Neo4j

[ekampp]

Hi.

We're actively using Neo4j in production with a Rails application, and we would really like to use the multi-db support that Rails 4 offers. My understanding from Gitter is that this is not yet supported and will probably only be supported on jRuby?

So I would love to spend some time helping to bring that feature into the driver for jRuby. I would love some guidance on where to start. Thanks.

@ekampp that is already part of the 4.1 driver in the 4.1 branch. I haven't released it yet because there is no compatible activegraph yet. But if you want to use the bare driver I could release it.

[ekampp]

In that case, I will start by checking out the branch and playing around with it. Thanks for the update.

@ekampp if you want to contribute then I would love your input in defining the driver API in idiomatic ruby, especially asynchronous and reactive sessions. Eventually, we will need to have all code examples form Neo4j Driver Manual 4.1 in ruby as for driver 1.7 in https://github.com/neo4jrb/neo4j-ruby-driver/blob/master/docs/dev_manual_examples.rb

I will have a look over the next week or so and give my thoughts.

@ekampp you might be interested in https://rubygems.org/gems/activegraph/versions/11.0.0.beta.1-java
It uses neo4j-java-driver-4.1.0.beta.1 with multi db support.

Great. We're in the process of migrating to a Java interpreter because of the announced expected lack of features for MRI here.
