  • Method Details

    • getParallelismInfo

      VertexParallelismInformation getParallelismInfo(JobVertexID vertexId)
      Returns a given vertex's parallelism information.
      Parameters:
      vertexId - vertex for which the parallelism information should be returned
      Returns:
      a parallelism information for the given vertex
      Throws:
      IllegalStateException - if there is no parallelism information for the given vertex

    • getAllParallelismInfo

      Map<JobVertexID,VertexParallelismInformation> getAllParallelismInfo()
      Gets a map of all vertex parallelism information.
      Returns:
      A map containing JobVertexID and corresponding VertexParallelismInformation.
