  6. object CanonicalRandomVertexCut extends PartitionStrategy with Product with 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.

  7. object EdgePartition1D extends PartitionStrategy with Product with Serializable

    Assigns edges to partitions using only the source vertex ID, colocating edges with the same source.

  8. object EdgePartition2D extends PartitionStrategy with Product with Serializable

    Assigns edges to partitions using a 2D partitioning of the sparse edge adjacency matrix, guaranteeing a 2 * sqrt(numParts) bound on vertex replication.

  9. object RandomVertexCut extends PartitionStrategy with Product with 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.
