EdgeRDD

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.

Abstract Value Members

  1. abstract def innerJoin[ED2, ED3](other: EdgeRDD[ED2])(f: (VertexId, VertexId, ED, ED2) ⇒ ED3)(implicit arg0: ClassTag[ED2], arg1: ClassTag[ED3]): EdgeRDD[ED3]

    Inner joins this EdgeRDD with another EdgeRDD, assuming both are partitioned using the same PartitionStrategy.

    Inner joins this EdgeRDD with another EdgeRDD, assuming both are partitioned using the same PartitionStrategy.

    other

    the EdgeRDD to join with

    f

    the join function applied to corresponding values of this and other

    returns

    a new EdgeRDD containing only edges that appear in both this and other, with values supplied by f

  2. abstract def mapValues[ED2](f: (Edge[ED]) ⇒ ED2)(implicit arg0: ClassTag[ED2]): EdgeRDD[ED2]

    Map the values in an edge partitioning preserving the structure but changing the values.

    Map the values in an edge partitioning preserving the structure but changing the values.

    ED2

    the new edge value type

    f

    the function from an edge to a new edge value

    returns

    a new EdgeRDD containing the new edge values

  3. abstract def reverse: EdgeRDD[ED]

    Reverse all the edges in this RDD.

    Reverse all the edges in this RDD.

    returns

    a new EdgeRDD containing all the edges reversed
