Marko A. Rodriguez updated TINKERPOP-1118:
------------------------------------------
Fix Version/s: (was: 3.2.1)
3.3.0
> SparkGraphComputer should use StarGraph, not VertexWritable.
> ------------------------------------------------------------
>
> Key: TINKERPOP-1118
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1118
> Project: TinkerPop
> Issue Type: Improvement
> Components: hadoop
> Affects Versions: 3.1.1-incubating
> Reporter: Marko A. Rodriguez
> Labels: breaking
> Fix For: 3.3.0
>
>
> {{SparkGraphComputer}} input RDDs are typed as:
> {code}
> JavaPairRDD<Object,VertexWritable>
> {code}
> The {{VertexWritable}} usage is a vestige from Hadoop and Giraph. In Spark,
> we don't need to have this wrapper and thus, we can reduce the overhead (one
> less object header) by making the input RDDs typed as:
> {code}
> JavaPairRDD<Object,StarGraph>
> {code}
> This would be a breaking change for graph providers that implement their own
> {{InputRDD}} and {{OutputRDD}}, however, the fix is trivial. Instead of {{new
> VertexWritable(vertex)}}, they would simply do {{StarGraph.of(vertex)}}.
