Scala 2.10 vs. 2.11 build of Janus?

rajdee...@...
 


    We are using Scala 2.11.8 in our project but Janusgraph build seems to use scala 2.10.(5/6?) libraries.

 We are wondering if there is near future release (perhaps through maven) with scala 2.11?

 If not, wondering if you already tried that and faced some issues.

We are facing compatability issues in using libraries specific to scala 2.11 such as logging when we try to use an older (several years old in fact) version of scala 2.10.6?

Thanks!

The Scala dependency is defined via Apache TinkerPop. JanusGraph is aligned currently with the TinkerPop 3.2.x branch, which is using Scala 2.10.5 (and Spark 1.6.1). Scala 2.11 (and Spark 2.0.2) is coming with TinkerPop 3.3, but there isn't a schedule in place for that yet.

I'm not aware if anybody has attempted to build JanusGraph against TinkerPop master branch, but I imagine there would be some work involved for any breaking changes.

You say it would take some work. Do you have a ballpark estimate my customer can use for planning? Presumably, when Tinkerpop 3.3 snapshots get to "candidate" stage, you start tooling for them. After that is it 2 months before you have a release? Is it 4 months? Is it six months? A ballpark number here would be really valuable for planning purposes.

Hi Raj,

Do you need Janusgraph's OLAP part?  If not, you might probably succeed in your scala 2.11 project if you simply exclude tinkerpop spark-gremlin from your janusgraph dependency. Note, I did not check the entire dependency tree. However, further proof for my suggestion stems from gremlin-scala which uses either scala-2.11 or scala-2.12:
https://github.com/mpollmeier/gremlin-scala/blob/v3.2.3.4/build.sbt

Cheers,    Marc
