Zookeeper Atomic Broadcast | System Design | High Level Design

Welcome to a concise guide on the ZAB protocol in Apache ZooKeeper! Join me as I explore how ZAB (ZooKeeper Atomic Broadcast) ensures consistency and reliability in distributed systems. What is ZAB? ZAB (ZooKeeper Atomic Broadcast) is a consensus protocol used by Apache ZooKeeper to manage distributed coordination. It ensures that all nodes in a ZooKeeper ensemble agree on the order and content of updates, maintaining consistency and reliability across the system. Benefits of ZAB - Strong Consistency: Provides strong consistency guarantees by ensuring that all nodes agree on the order and content of updates. - Reliability: Handles failures and network partitions gracefully, maintaining system availability and consistency. - Simplified Coordination: Centralizes coordination through a leader, simplifying the consensus process in distributed systems. In a ZooKeeper ensemble, the ZAB protocol ensures that all nodes agree on updates to znodes. When a client makes a change, the leader proposes the update and broadcasts it to all followers. Once a majority of followers acknowledge the update, it is committed and applied to all nodes, ensuring consistent data across the system.
