> Currently we use CC as our cluster coordinator. However, if we lose the CC node, all information about the cluster is lost. To overcome this, distributed applications typically have a distributed coordination service (i.e ZooKeeper) that can store and persist metadata about the cluster. We need to introduce coordination service API to allow for such extension to the system.
