Hi Christopher, You wrote "A modified client/library could be used to store objects that should be sharded, vs "standard" ceph treatment. In this model, each shard would be written to a seperate PG, and each PG would we stored on exactly one OSD. " but there is no way for a client to enforce the fact that two objects are stored in separate PG. Am I missing something ?
