> S3 now supports object tags, attributes which can be updated during the life of an object.
> S3A could use that to preserve the permissions/ACLs of objects when copied from elsewhere,
in particular from HDFS. This would ensure that data backed up from HDFS preserves all the
permission information needed when doing a recovery from S3 to HDFS.
> Azure WASB does exactly this already.
