Apache Curator
Apache Curator is a Java library that simplifies interaction with Apache ZooKeeper, a distributed coordination service. It provides high-level APIs, recipes for common distributed computing patterns, and robust error handling to manage ZooKeeper connections and operations. It is widely used in distributed systems for tasks like leader election, service discovery, and distributed locks.
Developers should use Apache Curator when building distributed applications that require reliable coordination, such as microservices architectures, cluster management, or real-time data processing systems. It abstracts the complexity of ZooKeeper's low-level APIs, reduces boilerplate code, and handles connection issues and retries automatically, making it essential for production-grade systems that depend on ZooKeeper for consistency and synchronization.
