Most consensus does not require heartbeat. Heartbeat is just the simplest way to detect a potential failure. > if you want a system that runs fast Consensus might affect the commit latency. It wont affect throughput that much though. But if you do not care, you can simply write to a consensus system without waiting for the commit. You can still get the serialization and replication.
