It's also possible to use boto3 without any credentials cached and instead use either s3fs or just rely on the config file reddit.
Probably not. It should work out to about same as looping over each key with boto3 maybe with an added call to list objects, but you need that in both cases — hume.

In my application's instance, I need to set permissions and owners so I have added that too can be comment out if not needed.
