I am trying to explore the possibility to use ceph object based storage in software development and client side deployment.I configured Rados gateway.I am able to access data with filename reference using S3 API and various other s3 clients.I wish to use Object ID to access the data rather then file name.Hence I want to know about the Objet ID assignment of files/object in Ceph.Can anyone tell l how to get ObjectID of object in Ceph? Is Ceph provides unique object ID of objects? Thanks in advance
