> _The current {{RebalancePartitioner}} implementation seems a little hacky for selecting a random number as the first channel index, and the following selections based on this random index in round-robin fashion._
> _Especially for the corner case of {{numChannels = Integer.MAX_VALUE}}, it would trigger next random index once reaching the last channel index. Actually the random index should be selected only once at the first time._
