> The controlled shutdown mechanism should be integrated into the software for better operational benefits. Also few optimizations can be done to reduce unnecessary rpc and zk calls. This patch has been tested on a prod like environment by doing rolling bounces continuously for a day. The average time of doing a rolling bounce with controlled shutdown for a cluster with 7 nodes without this patch is 340 seconds. With this patch it reduces to 220 seconds. Also it ensures correctness in scenarios where the controller shrinks the isr and the new leader could place the broker to be shutdown back into the isr.
