> against S3 (and other object stores), opening connections can be expensive, closing connections
may be expensive (a sign of a regression). 
> S3A FS and individual input streams should have counters of the # of open/close/failure+reconnect
operations, timers of how long things take. This can be used downstream to measure efficiency
of the code (how often connections are being made), connection reliability, etc.
