rationale:
Map/Reduce is an approach that collects data in parallel then
processes data in serial. A Map/Reduce job has 4 components/steps.
Batch : devide the targets into batches. Map : create threads to
collect data from/for each batch in parallel. Sort : aggregate
collected data by status. Reduce: (optional) process aggregated data
serially.
It is intended for efficiently process data on a large scale, with
fine grained control.
