> S3A is currently storing much more detailed metrics via StorageStatistics than are logged
in a MapReduce job. Eventually, it would be nice to get Spark, MapReduce and other workloads
to retrieve and store these metrics, but it may be some time before they all do that. I'd
like to consider having S3A publish the metrics itself in some form. This is tricky, as S3A
has no daemon but lives inside various other processes.
> Perhaps writing to a log file at some configurable interval and on close() would be the
best we could do. Other ideas would be welcome.
