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

1. Related Concepts Rabbitmq is a message proxy. In fact, it receives the messages generated by the producer and then delivers the messages to the consumer. In this process, it can be routed, buffered, or more configured rules to persist messages. Rabbitmq and message transmission generally use some terms: Producer (Producing): It means the end of the message. If a program sends a message, it is calledPr

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

If the exchange,queue,message is persistent, the message will be retained after the RABBITMQ reboot, and any link is not persisted and the message will not be restored. Persistence can reduce throughput by up to 10 times times (with SSD storage can be greatly mitigated) a
