Getting started with RabbitMQ-working queue and rabbitmq What is a work queue? A work queue is a processing method to avoid waiting for a number of resources or time-consuming operations. We encapsulate the task as a message and send it to the

In the implementation of Message Queuing, RABBITMQ is known for its robustness and reliability. The company's project has chosen it as the implementation of Message Queuing. About the mechanism and principle of MQ there are many articles on the web that you can see here, and we'll just talk about a few more confusing questions.1,binding Key and Routing keyThe binding key and the routing key are all just the set of characters that you are setting, exce

sends a message to see Routingkey. For example, a direct Exchange name is defined as X1, and then a queue name is Q1 with ROUTINGKEY=K1 bound to Exchange X1, and when a Routekey message arrives at K2, then only X1 The news can reach the Q1. Fanout-type exchange is better understood. It's a simple broadcast, and it ignores routingkey. So as long as there is a queue bound to fanout Exchange, messages sent th

RabbitMQ is a message queue server. here we are targeting the server environment of Python + Pika + RabbitMQ, let's take a look at how to use Python to operate the RabbitMQ server to implement the message queue routing function. RabbitMQ
20120825 Zheng Q: Why do MQ need to control the producer traffic? A: The trouble is: "The implementation and design of virtual machines like Erlang have not prevented users from throwing messages to the Message Queue of a process. When the message production speed is too fast, when the processing capacity of the process is exceeded, these messages are accumulated, occupying more memory and eventually causing VM crash. 』 Q: Why do I need to know that M
RABBITMQ Chinese translation, the main is the MQ letter: Message queue, that is, the meaning of messages queuing.

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 p
RabbitMQ Introduction: 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 requiring a dedicated connection to link them. Message passing refers to the process of communicating
