computeMaxEdgesToTargetExecutionVertex

public static int computeMaxEdgesToTargetExecutionVertex(int targetParallelism,
                                                         int sourceParallelism,
                                                         DistributionPattern distributionPattern)

Given parallelisms of two job vertices, compute the max number of edges connected to a target execution vertex from the source execution vertices. Note that edge is considered undirected here. It can be an edge connected from an upstream job vertex to a downstream job vertex, or in a reversed way.

参数:

targetParallelism - parallelism of the target job vertex.

sourceParallelism - parallelism of the source job vertex.

distributionPattern - the DistributionPattern of the connecting edge.
