Message queuing middleware is an important component in a distributed system. It mainly solves the problems of application coupling, asynchronous messaging, traffic cutting, etc. It achieves high performance, high availability, scalability and eventual consistency architecture, which is indispensable for large distributed systems. Middleware.
At the same time, many Internet companies now have higher and higher technical requirements for Java back-end developers, message queues have become a hot topic in interviews, and even small partners have been subjected to soul torture! (Message queues are not very good, do you need to really move bricks for the multi-million-level business of a big factory?)
- Why are the messages repeated?
- How to ensure that messages are not re-consumed? How to ensure that consumption is idempotent?
- How to ensure the reliable transmission of messages? What if the message is lost?
- How to ensure the order of messages?
In order to let the friends who are learning RocketMQ and RabbitMQ not step on the pits in their studies, we specially compiled RocketMQ and RabbitMQ from entry to principle technical points into a 30W word study notes manual!

RabbitMQ study notes manual
RabbitMQ, as a currently widely used messaging middleware, plays an important role in enterprise applications and microservice applications. Especially in some typical application scenarios and business modules, it has an important role, such as business service module decoupling, asynchronous communication, high concurrency current limit, timeout delay processing, etc. have a wide range of applications! This note fully analyzes these from theory to actual combat, it is very worth learning, let's take a look at the general catalog first!

to sum up
In today's era, systems are becoming more and more complex, and the more data comes, the interaction between systems becomes more and more important, but also more and more difficult. The message middleware plays an important role as an intermediate bridge. Therefore, in interviews, questions about message middleware are often asked. From its use to its principle design, it will be a point of interest to interviewers.
If you are still learning RocketMQ and RabbitMQ middleware, these 2 study notes manuals are very suitable for reference study!
