7. Description of the issue: Hi, We are surprised by the pgbackrest activity profile with very numerous GetObjectTagging requests at the S3 Scality ring. Is this "normal" behavior, is it due to our configuration? Thank you for your insight.

We do not explicitly fetch tags (i.e. https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObjectTagging.html) so not sure where this is coming from. It could be that Scality is piggy-backing these requests on a list request.

Thank you for your response, we are also questioning Scality on this subject.

Closing since there has been no further word on this. I would be curious to know if you got a response from Scality.
