Steve Loughran commented on HADOOP-13453:
-----------------------------------------

# these should all go into org.apache.hadoop.fs.s3a.Statistic & Instrumentation
# tracking total & ongoing dynamoDB request rates could be useful, as it will 
help identify when you've over/under provisioned your DDB.
# include stats on detected inconsistencies
# include in {{S3AFileSystem.toString}}.
