> As part of SAMZA-220, a more radical patch was proposed. This patch appears
> to improve SystemConsumers' performance pretty significantly, while also
> reducing its complexity. The decision was made to move this change into the
> 0.8.0 release, rather than the 0.7.0 release, since it's a fairly risky
> change.
> This ticket is to explore updating SystemConsumers to eliminate almost all
> loops in order to increase performance in the Samza container.
