   > It is not sufficient to just define the replication factor. The replication/recovery behavior completely changes based on the replication scheme. E.g. for EC, we are talking about picking some coordinator during recovery. How do you abstract away behavior like that?
   
   I am not sure If I understand this question. Offline-recovery and co-ordinator election is an internal implementation detail of EC replication scheme. The only role of storage-class is to *select* and *configure* the required configuration scheme. If EC 3:2 is configured we will have EC 3:2 containers created which will be managed by SCM as EC 3:2 containers.
