----------------------------------------------------

Hi, [~a.pejakovic], thanks for picking this up. I left some comments on RB. Also, ideally, we should update the flush-ms in KafkaSystemProducerMetrics as well.

Thanks!

> The current metrics like process_ms, choose_ms, etc. only works at millisecond level precision and results in erroneous reports only containing values greater than 1ms latency. This does not work when each container's actual throughput is at multiple K qps. The precision of those metrics should be at nano-second level.
