I. What is Message Queuing?A message is the data that is transferred between apps. Messages can be very simple, such as containing only text strings, or they can be more complex and may contain embedded objects.Message Queuing is a way of communicating between applications, which can be returned immediately after a message is sent, and the message system ensures reliable delivery of the message. The message publisher simply publishes the message into MQ without having to take care of who gets it
RABBITMQ Installation Steps
(1) To install RABBITMQ under Linux, you need to install the Erlang installation package first. Because RABBITMQ is written in Erlang language, you need to configure Erlang's environment first.
(2), Erlang installation:

What is RABBITMQ? MQ (Message queue) message middleware, which is generally deployed in cluster mode, mainly provides the receiving and sending of messages, and realizes the synchronization of messages between each micro-service. Principle Introduction RABBITMQ is based on the distributed nature of Erlang (RABBITMQ is implemented by the Erlang architecture, so ra
, and MQ follows the specific implementations and products of the AMQP protocol.
Usage Scenarios
In the project, some operations without immediate return and time-consuming are extracted and processed asynchronously, which greatly saves the request response time of the server and improves the throughput of the system.
Meaning
RABBITMQ is a popular open source Message Queuing system, developed in Erlang language.
RabbitMq window set up the process, some of the internet is not quite clear, so personally fencing the test process, referring to a lot of people's information, thank you to the great God's valuable informationThe first step: Install RABBITMQ operating environment, similar to a virtual machine Dongdong1.otp_win32_19.0.exe:https://www.erlang.org/32-bit and 64-bit according to the personal system installation
HelloWorld introduction RabbitMQ: it can be regarded as a "post office" to receive and re-transmit messages ". The sender and receiver interact through the queue. The size of the queue can be viewed as infinite. multiple senders can be sent to one queue, and multiple recipients can also receive messages from one queue. Introduction to co... HelloWorld

In our previous blog post, we used direct exchange instead of fanout exchange, and this time we looked at topic exchange.First, Topic Exchange introductionTopic Exchange and direct Exchange are similar and are matched by routing key and binding key, but topic Exchange can set multiple standards for routing key.A direct router is similar to an exact query in an SQL statement; The topic router is somewhat similar to a fuzzy query in an SQL statement.Do you remember? We introduced the classificatio
In the previous article using the RABBITMQ Series in node. js a Hello world I used a task queue, but the scene at the time was to send a message to a consumer, and in this article I'll discuss scenarios with multiple consumers.In fact, the problem with the core of the task queue is to avoid dealing with time-consuming tasks immediately, that is, the synchronous pattern of avoiding request-response. Instead, we use a scheduling algorithm that allows th

The most important role of message middleware is decoupling, the most sta
How to implement priority queue based on RabbitMQOverview
For various reasons, up to now, RabbitMQ has not implemented a priority queue, but only implemented priority processing for Consumer.
However, for various reasons, Priority Queues are required at the application layer, so the requirement is: how to add priority queue features to RabbitMQ.
