GroupByKey

case class GroupByKey(in: CompNode, wfk: WireReaderWriter, gpk: KeyGrouping, wfv: WireReaderWriter, nodeSinks: Seq[Sink] = ..., bridgeStoreId: String = ...) extends ProcessNodeImpl with Product with Serializable

The GroupByKey node type specifies the building of a CompNode as a result of partitioning an exiting key-value CompNode by key
