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
Installing Rabbit MQRabbit MQ is built on the powerful Erlang OTP platform, so installing Rabbit MQ is premised on the installation of Erlang. Download the installation from the following two connections 3.2.3 version:
Download and install ERALNG OTP for Windows (VR16B03)
Run Install Rabbit MQ Server Windows Installer (v3.2.3)

This series of blog mainly from the practice of the theory of two points of view with everyone step-by-step understanding of the familiar rabbitmq, a total of basic, advanced, high-level article. The basic article mainly introduces some basic concepts of MQ, RabbitMQ's historical background, and some of the same types of technology, build a running environment and write a simple program, advanced article we will use

Brief introduction
RabbitMQ: Accepts message re-delivery messages, which can be treated as a "post office." The sender and receiver interact through the queue, the size of the queue can be considered unlimited, multiple senders can take place to a queue, and multiple receivers can accept messages from one queue.
Code
The protocol used by RABBITMQ is AMQP, and the recommended client for Python is

Work QueuesIn the first tutorial we wrote programs to send and receive messages from a named queue. In this one we'll create a work Queue that'll be used to distribute time-consuming tasks among multiple wor Kers.The main idea behind work Queues (AKA: task Queues) was to avoid doing a resource-intensive Task immediately a ND has to-wait for it to complete. Instead We schedule the task to is done later. We encapsulate a task as a message and send it to the queue. A worker process running in the b
