What is the purpose of RocketMQ in Java?

In Java, RocketMQ is a distributed message queue system primarily used for asynchronous communication, decoupling messaging senders and receivers, and caching messages. RocketMQ can achieve high reliability and high throughput message delivery, making it suitable for messaging communication needs in large-scale distributed systems. It provides features such as persistent message storage, reliable message transmission, message broadcasting, and cluster consumption, making it a commonly used middleware solution for messaging.
