[jira] [Created] (SAMZA-738) Samza Timer based metrics does not have enough precision

Yi Pan (Data Infrastructure) created SAMZA-738:
--------------------------------------------------

             Summary: Samza Timer based metrics does not have enough precision
                 Key: SAMZA-738
                 URL: https://issues.apache.org/jira/browse/SAMZA-738
             Project: Samza
          Issue Type: Bug
            Reporter: Yi Pan (Data Infrastructure)


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.
