> Sqoop uses MapReduce jobs to export files back to a table in the database. The degree
of parallelism is controlled by the number of splits; i.e., the number of input files used.
The bottleneck in the system, though, is likely to be the database itself.
> Users should have the ability to tune the number of parallel exporters being used to
a degree appropriate to their database deployment.
