abstract class EdgeRDD[ED] extends RDD[Edge[ED]]

EdgeRDD[ED, VD] extends RDD[Edge[ED]] by storing the edges in columnar format on each partition for performance. It may additionally store the vertex attributes associated with each edge to provide the triplet view. Shipping of the vertex attributes is managed by impl.ReplicatedVertexView.
