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.
