One of the most important virtues of any distributed system is its ability to detect failures in any of its subsystems before things go havoc. Early detection of failures helps in taking preventive actions and ensuring that the system stays fault-tolerant. The conventional way of failure detection is by using a bunch of heartbeat messages with a fixed timeout, indicating if a subsystem is down or not.
