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

RabbitMQ is a message queue server. in this article, we will learn how to deploy the Python + Pika + RabbitMQ environment and how to implement the workflow queue. if you need a friend, refer to the Chinese translation of rabbitmq, it is mainly on the mq letter: Message Queue, that is, the meaning of Message Queue.

A brief introduction of RABBITMQ PV website architectureWhat is RABBITMQ?
MQ is all called the message queue, and Message Queuing (MQ) is an application-to-application communication method. Applications communicate by reading and writing messages to and from the queue (data for the application) without having to connect them with private links. Message passing refers to the process of communicating
The main features of AMQP are message-oriented, queue, routing (including point-to-point and publish/subscribe), reliability, and security.The main thing to say in AMQP is two components: Exchange and queue (there are also changes in AMQP 1.0), as shown in the following figure, the green X is Exchange, the red is the Queue, both on the Server side, also called the Broker, which is part R ABBITMQ is implemented, while the blue one is the client, usually there are two types of Producer and Consume

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.

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
