[ceph-users] Etag change of a parent object

Hi, shouldn't etag of a "parent" object change when "child" objects are added on s3? Example: 1. I add an object to test bucket: "example/" - size 0 "example/" has an etag XYZ1 2. I add an object to test bucket: "example/test1.txt" - size 12 "example/test1.txt" has an etag XYZ2 "example/" has an etag XYZ1 ... should this change? I understand that object storage is not hierarchical by design and objects are "not connected" by some other means than the bucket name. Kind regards, Rok
