Is listing Amazon S3 objects a strong consistency operation or eventual consistency operation?
The List Objects operation appears to be eventually-consistent, even for new objects. According to a support forum post from an AWS employee ChrisP@AWS:
Read-after-write consistency is only valid for GETS of new objects - LISTS might not contain the new objects until the change is fully propagated.
