Distributed coordination service: ZooKeeper is a distributed coordination service used to manage and maintain metadata information in distributed systems, such as configuration and status information.
High performance: ZooKeeper utilizes a high-performance replication protocol, enabling it to provide superior performance and throughput.
Reliability: ZooKeeper utilizes a majority-based mechanism to ensure data consistency and reliability, meaning as long as the majority of nodes have successfully written, the entire cluster considers the write operation successful.
Sequential consistency: ZooKeeper ensures that client read and write requests are executed in order, without any data races or disorder.
Easy to use: ZooKeeper provides a user-friendly API for easy data reading, writing, and monitoring.
Scalability: ZooKeeper supports cluster mode, which allows nodes to be dynamically expanded as the system scales up, providing increased performance and availability.
