> Currently the AM sends a set of all the topics and partitions to the container, which then groups them by partition and assigns each set to a task instance. By moving the grouping to the AM, we can assign arbitrary groups to task instances, which will allow more partitioning strategies, as discussed in SAMZA-71.
