Hi

Looking at this example, doing the "rebalance" (e.g messageStream.rebalance().map(...) ) operation on heavy load stream wouldn't slow the stream ? is the rebalancing action occurs only when there is a partition change ? 

it says that "the rebelance call is causing a repartitioning of the data so that all machines" is it actually changing the num of partitions of the topic to match the num of flink operators ?
