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,
In the previous article, we mentioned the problem of Asynchrony in the short series of scalable architectures. It was recommended to use RABBITMQ to do the task queue implementation. This article takes node. js as an example to actually manipulate how to interact with RABBITMQ.IntroducedRABBITMQ is a message agent. Its initial thought was particularly simple: to accept and forward messages. You can think of
