>
> In a heavy load read/write cluster, frequent leader step down is observed
> because of lost the majority heartbeat.
> The investigation shows that follower side heartbeat process is very quick,
> while the leader side heartbeat latency is high. See the attached metrics
> diagram.
> This task aims to use seperate grpc channel for heartbeat to reduce the
> latency introduced by the network queuing.
