So, changing it to 1 will create an issue for existing system if they will try to use upgrade release without knowledge of this configuration. However, recently while doing testing on high throughput bookies, we figured out that 16 bookie channel was the bottleneck and we need to make it configurable to tune it based on number topics and per bookie traffic. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
