Subject [jira] [Created] (AURORA-52) Track percentile stats about replicated log write latency

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

             Summary: Track percentile stats about replicated log write latency
                 Key: AURORA-52
                 URL: https://issues.apache.org/jira/browse/AURORA-52
             Project: Aurora
          Issue Type: Story
          Components: Scheduler
            Reporter: Bill Farner
            Priority: Minor


We currently track the aggregate log append write latency, but this doesn't tell the whole
story.  We've encountered situations in production where kernel and disk issues can lead to
a long tail of high latency appends, which are buried in the aggregate.
