Today the Modify Collection supports the following properties to be modified
1. maxShardsPerNode 2. rule 3. snitch 4. policy 5. collection.configName 6. autoAddReplicas 7. replicationFactor 1-4 seems something we should get rid of because we have the AutoScaling Policy framework? 5> Can anyone point out the use-case for this? 6> autoAddReplicas can be changed as a clusterprop and modify-collection API ? Hmm. Which one is supposed to win? 7> We need to allow a user to change replicationFactor. But how does this help? We have nrtReplicas / pullReplicas / tlogReplicas so changing this sounds just confusing? Or allow changing all replica types ?
