> 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.
