You are probably thinking of Amazon's S3 where adding a random prefix to object names was a common performance optimization in the past, but I think they fixed that recently. Anyways, common prefixes are very common in Ceph and no problem. For example, all objects within an rbd imge have the same prefix. Paul Am Do., 27.

The objects are copied to various buckets like bucket_YYYYMMDD/dir1/dir2/dir3/yyyy/mm/dd. This setup minimize some internal code change when moving from NFS to object store. > > I heard that CRUSH may NOT evenly balance OSDs if there are many common leading characters in the object name?
