ABSTRACT
In this paper, we study the benefits and overheads of lazy
MapReduce processing, where the input data is partitioned
and only the smallest subset of these partitions are processed
to meet a user's need at any time. We also develop guidelines
for successfully applying the lazy MapReduce computation
technique to reduce processing times of analysis tasks.
