org.apache.flink.runtime.executiongraph.VertexInputInfoStore

public class VertexInputInfoStore
extends Object

A store contains all the JobVertexInputInfos. Note that if a vertex has multiple job edges connecting to the same intermediate result, their DistributionPattern must be the same and therefore the JobVertexInputInfo will be the same.
