About:
Apache ZooKeeper is a high-performance coordination service for distributed applications. It provides a simple interface for configuration management, naming, distributed synchronization, and group services. Its main value is enabling developers to build robust distributed systems without having to implement consensus protocols from scratch.

Key Features:

Hierarchical key-value store for configuration
Reliable distributed synchronization primitives
Guaranteed ordering and atomicity
Watch mechanism for real-time notifications

Use Cases:

Service discovery and registration
Distributed locking and leader election
Configuration management across clusters

Alternatives:

etcd – etcd uses Raft consensus and is popular in Kubernetes ecosystems, while ZooKeeper uses Zab protocol and has been historically dominant in the Hadoop ecosystem.
Consul – Consul provides built-in service discovery and health checking, whereas ZooKeeper focuses primarily on coordination primitives.
