What is Apache ZooKeeper?
Apache ZooKeeper is a management tool developed by Apache Software Foundation. It is a distributed and open-source coordination service for distributed applications designed to simplify the development of reliable distributed systems. ZooKeeper provides a highly reliable and distributed file system for storing and syncing configurations, naming services, and other important data.
How Apache ZooKeeper Works
Apache ZooKeeper works as a reliable coordination system for distributed Java applications. It is a distributed application that uses a simple architecture to solve coordination issues that arise in distributed systems. ZooKeeper follows a simple data model as well as distributed communications protocols. It allows distributed Java applications to coordinate and perform various tasks, such as configuration management, synchronization, group messaging, and naming services.
