Interviewer: How did you learn RabbitMQ? I feel almost the same as Yushu Linfeng, romantic and suave...

What are the usual application scenarios for message queues in development?

Let's cite a few examples:

1. Asynchronous processing of tasks

The message queue informs the message receiver to perform asynchronous processing for operations that do not require synchronous processing and are time-consuming. Improve the response time of the application.

2. Application decoupling

MQ is equivalent to an intermediary. The producer interacts with the consumer through MQ, which decouples the application.

3. Peak cutting and valley filling

For example, the order system will write data to the database when placing an order. However, the database can only support about 1,000 concurrent writes per second, and no matter how high the concurrency is, it is easy to crash. During the low peak period, there are more than 100 concurrency, but during the peak period, the concurrency will suddenly surge to more than 5000. At this time, the database must be stuck.

....................................... There are many more, we will not list them one by one.

So why use MQ?

Because in the project, some time-consuming operations that do not need to be returned immediately can be extracted and processed asynchronously, and this asynchronous processing method greatly saves the server's request response time, thereby improving the throughput of the system .

So how to learn systematically? Today I brought you a systematically combed "RabbitMQ of Message Middleware" study notes, this note system combed RabbitMQ, from entry to grave and interview questions collection, this note is a leader of the goose factory In summary, there is only one copy on the entire network, not much to say directly on the dry goods! Will learn from the following ten aspects:

1. Overview of messaging middleware
2. Install and configure RabbitMQ
3. Getting started with RabbitMQ
4. AMQP
5. RabbitMQ working mode
6. Spring Boot integrates RabbitMQ
7. RabbitMQ advanced
8. RabbitMQ cluster
9. RabbitMQ high availability cluster [extended]
10. RabbitMQ application and interview
