> There should be a graceful way of decommissioning the broker so that there is 
> absolutely 0 data loss. Decommissioning is not necessarily related to 
> replication (Kafka-50).
> There should be a way to get the broker out of the cluster only from the 
> produce side. Consumers should be able to continue keep pulling data. When 
> the administrator is sure that all data has been consumed by consumers, 
> broker node can be removed permanently.
> Same would be useful for rolling upgrades without any message loss.
