foreword
Message queues have gradually become the core means of internal communication in enterprise IT systems. It has a series of functions such as low coupling, reliable delivery, broadcasting, flow control, and eventual consistency, and has become one of the main means of asynchronous RPC. Although it is said that the current situation is that Kafka is more popular, the more extensive ones should still belong to the old-fashioned RabbtiMQ and the RocketMQ independently developed by Alibaba.
Alibaba must still have the right to speak about MQ-related content, especially the use of RocketMQ, so what we want to share today is actually a summary of the ten-year development experience of Alibaba P8, written in this book "RabbitMQ+ RocketMQ" technical manual, you have to sigh this superb manual after reading it!

Summarize
In fact, the communication between general business systems will use RabbitMQ/RocketMQ, which requires the support of complex message routing functions. Kafka is only used in real-time computing scenarios of big data, which requires a simple consumption model but ultra-high throughput.
Therefore, as a Java development, it is more important to focus on RabbitMQ and RocketMQ for learning. Finally, ask yourself again, how much do you know about MQ? To what extent will it be used? If it's not enough, you can't stop learning.
The above MQ manual is definitely 100% free to share with you, but I need your support for my article!
