PJ Van Aeken commented on FLINK-1962:
-------------------------------------
I did a new commit to my personal Github, which gives you a better idea of
what I am currently doing.
But I absolutely agree that the way I am currently doing it is a maintenance
and sync nightmare. I would be more than willing to implement it as a wrapper
of the Java API but there are some problems. Most of them are easily fixed, but
the one I can't seem to fix is dealing with the constraints of Vertices/Edges
key and values.
Basically, I want the key and value types to be either scala case classes or
scala primitives. For case classes, you can force implementation of Ordered and
Serializable (which is conform to the java constraints) but scala primitives
implement neither Ordered nor Serializable. You can solve part of this by doing
[K : Ordered[K]] but Ordered doesn't implement Serializable either. I've tried
many things and none of them compile for both scala primitives and case
classes. Is there something I am missing here?
