Class PartitionStrategy.RandomVertexCut$

Object

org.apache.spark.graphx.PartitionStrategy.RandomVertexCut$

All Implemented Interfaces:

java.io.Serializable, PartitionStrategy, scala.Equals, scala.Product

Enclosing interface:

PartitionStrategy

public static class PartitionStrategy.RandomVertexCut$
extends Object
implements PartitionStrategy, scala.Product, scala.Serializable

Assigns edges to partitions by hashing the source and destination vertex IDs, resulting in a random vertex cut that colocates all same-direction edges between two vertices.
