How ZooKeeper Leader Election Ensures High Availability in Distributed Systems

ZooKeeper's leader election mechanism creates temporary sequential nodes under a shared /ELECTION path, allowing services to elect a primary node, monitor predecessor nodes, and automatically re-elect a new leader when the current one fails, ensuring continuous high availability across distributed applications.
