--------------------------------------
[~apurtell], [~stack] looks like a nice to have, but not sure how much this is
actually used...
> Export dry run mode.

> We encountered customer experiencing poor performance on Exports and we've
> spent some time trying to isolate the performance bottlenecks. It was
> suggested to add a "dry run mode" that just scans the table but does not emit
> data to hdfs. This would be really useful for determining if problems are on
> the write path or the read path.
