Explain parallel efficiency of MapReduce.
Explain parallel efficiency of MapReduce. [5]
Parallel efficiency (E) measures how effectively a parallel system utilizes its computing resources compared to an ideal scenario. For MapReduce, it indicates how well the framework scales as more nodes are added to the cluster. E = S / P Where: - S = Speedup (ratio of sequential time to parallel...
