Guozhang Wang commented on KAFKA-1071:
--------------------------------------
I tested the Random implementation a bit and the results look good. One thing
of using timestamp is that producer clients may start at roughly the same time,
and I do not know if there is a correlation between numeric difference of seed
values and the numeric difference between the generated values.
> The random partition selected in DefaultEventHandler is not random across
> producer instances
