Wake up after being repeatedly upset by MQ! Hate code out this MQ manual to help the journey of autumn recruitment

Message Queuing Middleware is an important component of distributed system ,

Mainly solve application coupling 、 Asynchronous messaging 、 Flow cutting , Achieve high performance 、 High availability 、 Scalable and ultimately consistent architecture , It is an indispensable middleware for large distributed system .

At the same time, many Internet companies now have Java The technical requirements of back-end developers are also getting higher , Message queuing has also become a hot topic in the interview , There are even little friends who have been tortured by their souls ！（ Message queuing is not very good , Do you really need to move bricks for the hundreds of millions of businesses of big factories ？）

• Why does the message repeat ？

• How to ensure that messages are not consumed repeatedly ？ How to ensure that consumption is idempotent ？

• How to ensure the reliable transmission of messages ？ What if the news is lost ？

• How to ensure the order of messages ？

In order not to learn RocketMQ and RbbitMQ My friend stepped on the pit , Specially RocketMQ and RabbitMQ The technical points from introduction to principle have been sorted out and written into a 30W A notebook of words ！

RabbitMQ manual

RabbitMQ  As a widely used message oriented middleware , In enterprise applications 、 Microservices play an important role in applications . Especially in some typical application scenarios and business modules , For example, the business service module is decoupled , asynchronous communication , High concurrency current limit , Timeout and delay processing are widely used ！

This note fully analyzes these from theory to practice , It's worth learning , Let's take a look at the general catalogue first ！

summary

Today's era , The system is becoming more and more complex , More data , The interaction between systems becomes more and more important , At the same time, it becomes more and more difficult . And the message middleware plays an important role as an intermediate bridge . therefore , The interview will often be asked questions about message middleware . From its use to its principle design , Will be a point of interest to the interviewer .
