Class PartitionStrategy.CanonicalRandomVertexCut$

Object

org.apache.spark.graphx.PartitionStrategy.CanonicalRandomVertexCut$

All Implemented Interfaces:

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

Enclosing interface:

PartitionStrategy

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

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