Review Comment:
hi @jackye1995 if a object storage path has millions of files, S3 listing
usually takes very long time since it has to go thru all the keys recursively.
This behavior can be improved by listing files with hash prefix in parallel
like <location>/data/00, <location>/data/01, <location>/data/0a etc.
