> Currently, in the need for clients to be more evenly balanced, stateful tasks should
be distributed in such a manner that it will be spread equally. However, for such an awareness
to be implemented during task assignment, it would require the need for the present rebalance
protocol metadata to also contain the number of state stores in a particular task. This way,
it will allow us to "weight" tasks during assignment.
