Neha Narkhede commented on KAFKA-343:
-------------------------------------
Yang,
Do we know the impact of this patch on the leader election latency ? The idea
of having a controller do state changes was the possible reduction in leader
election latency. Curious to know if there are any numbers to support this
assumption ?
> revisit the become leader and become follower state change operations using
> V3 design
