Hi folks, I created a feature request ticket to call for bucket-level redirect_zone (https://tracker.ceph.com/issues/61199), which is basically an extension from zone-level redirect_zone. I found it helpful in realizing CopyObject with (x-copy-source) in multisite environments where bucket content don't exist in all zones. This feature is similar to what Matt Benjamin suggested about the concept of "bucket residence". In my own prototyping affect, redirecting feature at bucket level is fairly straightforward. Making use of it with CopyObject is trickier because I haven't found a good way to get the source object policy when RGWCopyObj::verify_permission() is called. Anyway, I will continue to explore this idea and hope to get more support of it. Thanks, Yixin
