Reynold Xin commented on SPARK-3376:
------------------------------------
It is definitely possible. We should evaluate the benefit. What I find recently
is that with SSDs and zero copy send, disk-based shuffle can be pretty fast as
well. That is, the network (assuming 10G) is the new bottleneck.

> I think a memory-based shuffle can reduce some overhead of disk I/O. I just
> want to know is there any plan to do something about it. Or any suggestion
> about it. Base on the work (SPARK-2044), it is feasible to have several
> implementations of shuffle.
