---------------------------------------------------
Hi [~ste...@apache.org], I saw that a few classes , such as S3AInstrumentation,
implement IOStatisticsSource and use IOStatisticsStore to track different
counters. Is this the approach that you think we should follow?
Could you also help explain what's the consumer of the IOStatistics?
