---------------------------------
Linking a dupe- AURORA-73: Break out storage latency and log latency into
percentiles
> Track percentile stats about replicated log write latency

> Labels: O3

> 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.
