Gabriel Reid commented on CRUNCH-210:
-------------------------------------
Looks good to me, other than one nitpick: I like the addition of a parameter to
specify the number of reducers, but I don't think that it should be called
parallelism -- I would prefer either numReducers or numPartitions.
The only other place that the name "parallelism" is used is in Cartesian, and
it has a totally different meaning there, so I think using the same name here
is confusing (it threw me off when I first saw it in the patch).
