Vahid Hashemian commented on KAFKA-3818:
----------------------------------------
[~hachikuji] Since _round robin_ provides a more balanced output I'm curious
why _range_ is still being used as the default strategy for the consumer.
> Change Mirror Maker default assignment strategy to round robin

> It might make more sense to use round robin assignment by default for MM
> since it gives a better balance between the instances, in particular when the
> number of MM instances exceeds the typical number of partitions per topic.
> There doesn't seem to be any need to keep range assignment since
> copartitioning is not an issue.
