[ceph-users] Consequence of maintaining hundreds of clones of a single RBD image snapshot

Hello, My use-case involves creating hundreds of clones (~1,000) of a single RBD image snapshot. I assume watchers exist for each clone, due to the copy-on-write nature of clones. Should I expect a penalty for maintaining such a large number of clones: cpu, memory, performance? If such penalty does exist, we might opt to flatten some of the clones. Is consistency guaranteed during the flattening process? In other words, can I write to a clone while it is being flattened? Perspectivus
