Anton Vinogradov commented on IGNITE-1093:
------------------------------------------
Updated points
SupplyNode register N = cctx.config().getRebalanceThreadPoolSize() listeners
per cache at start.
DemandNode register N listeners per cache on new assignment and sends N
requests to supply node.
Each request contains 1/N part of partitions.
So, Supply pool will deliver 1/N partitions to each Demand node listener.
And as described before we have M batches for each listener in-flight.
> Rebalancing with default parameters is very slow
