>
> Currently, nodes send heartbeats to the NCM periodically in order to indicate
> that they are actively participating in the cluster. As we move away from
> using an NCM, we need these heartbeats to go somewhere else. ZooKeeper is a
> reasonable location to push the heartbeats to, as it provides the HA that we
> need
