    Description

      A straggler is a machine that takes an unusually longer time to complete tasks than other machines do. Straggler is usual in large-scale distributed systems. Earlier straggler detection and handling can significantly reduce query response times. So, we need to add the straggler detector. Detected stragglers should be added to the black list, and they should not used for processing.
