Apache ZooKeeper - Centralized Service for Distributed Coordination
Apache ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. It is used to build distributed applications.
Project Introduction
Summary
Apache ZooKeeper is a critical component for distributed systems, providing a robust and reliable service for coordination and state management.
Problem Solved
Managing coordination, configuration, and synchronization across distributed systems is complex and error-prone. ZooKeeper provides a robust, reliable service to simplify these tasks.
Core Features
Distributed Configuration Management
Provides a hierarchical namespace similar to a file system, allowing applications to store and retrieve configuration data.
Synchronization Services
Offers primitives like distributed locks, barriers, and queues essential for coordinating processes in distributed environments.
Tech Stack
Use Cases
Apache ZooKeeper is widely adopted in various distributed computing scenarios to manage state and coordination among nodes.
Leader Election
Details
Multiple nodes competing for a single resource or task can use ZooKeeper to elect a leader and ensure only one node performs the designated role at a time.
User Value
Ensures high availability and prevents split-brain scenarios in clustered applications.
Centralized Configuration Management
Details
Applications can store and retrieve configuration data centrally, allowing dynamic updates without restarting services.
User Value
Simplifies configuration deployment and management across a large number of distributed services.
