What does java RabbitMQ message queue mean?

This article mainly introduces the relevant knowledge of what java RabbitMQ message queue refers to, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading what this java RabbitMQ message queue refers to. Let's take a look.

1. RabbitMQ is a high concurrency and high reliability AMQP message queuing server implemented with Erlang.

2. The usage scenarios are improving system response speed, system stability, asynchronization of service invocation, and so on.

Improve system response speed

Tasks are processed asynchronously. The long-time-consuming operations that do not require synchronous processing are processed asynchronously by the message queue notifying the message receiver. Improve the response time of the application.

Improve system stability

The system hung up the relationship, and the operation content was put into the message queue.

Service invocation asynchronization

The service does not have a direct invocation relationship, but communicates through the queue

Service decoupling

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

Sorting guarantees FIFO

Follow the first-in-first-out characteristics of the queue

Eliminate peak value

Speed up asynchronously (send messages), improve system stability (multiple system calls), service decoupling (5-10 services), sequencing guarantee, eliminate peak value
