Yes, see this blog post that explains this in a bit more detail: http://www.ksingh.co.in/blog/2017/01/15/ceph-object-storage-performance-improvement-using-indexless-buckets/ > Whats going under the hood when I delete RGW object?

IIUC each RADOS object is in 1:1 correspondence with a single stripe unit, so all stripe objects are simply deleted when the RGW object is deleted/when garbage collection runs. _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
