Thanks Todd
for the valuable information.
Partition re-balance: I am testing a scenario (1 topic with 8 partitions, 3
replicas with 3 brokers) where I brought down one broker2 acting as a
leader to partitions then immediately leaders and isr's have changed to 2
live brokers but not evenly balance
There’s no data moved when a PLE occurs, so that is not the problem here.
The issue is that the controller reelects all partitions at the same time.
This forces all the replica fetchers on the broker to stop and restart (for

There’s two things that people usually mean when they talk about
rebalancing.
One is leader reelection, or preferred replica election, which is sometimes
confusingly referred to as “leader rebalance”. This is when we ask the
controller in the cluster to pick the preferred replica for all partition

I am confused about the re-balancing?
How and where to configure the re-balancing option?
