Description: The heartbeat mechanism is a method used in distributed systems to monitor the health of nodes. This mechanism allows components of a system to verify that other nodes are operational and functioning correctly. Through the periodic emission of ‘heartbeat’ signals, nodes can communicate with each other and detect failures or outages in the system. This process is crucial for maintaining the integrity and availability of services in distributed environments, where communication and coordination among multiple nodes are essential. The heartbeat mechanism not only helps identify issues but can also be used for automated recovery tasks, ensuring that the system continues to operate efficiently. In the context of distributed computing frameworks, the heartbeat mechanism plays a fundamental role in managing cluster resilience and stability, allowing nodes to remain synchronized and operational.
