queue is a buffer, that stores messages. A consumer is a user application that receives messages. The core idea in the messaging model in RabbitMQ is, the producer never sends any messages directly to a queue. Actually, quite often the producer doesn ' t even know if a message would be delivered to any queue at all.Instead, the producer can only be send messages to an exchange. An

现实生活中，机器的配置不同，有的性能高，有的性能低，有可能A机器处理了四条消息，B机器一条消息还没处理完，要是按照轮询方式来分发消息的话，那就是A机器一直是空闲，B机器有一大丢消息处理不完。我们在部署集群的时候，往往要添加一个服务器的权重值，那个服务器性能好就多给它点儿任务，那么在RabbitMQ怎么办呢？RabbitMQ里的公平分发是指你有多大本事就干多少活儿，比如A机器处理速度快RabbitMQ就多给它发，B机器处理速度慢就给它少发。RabbitMQ是这样做的，Server端在给Client发消息时会先检查Client端还有多少条消息没有处理完，如果当前队列里消息大于1就不发，队列里为空就发。只需要在**消费者**端加一条短短的

The MQ whole process (message queue) is also known as the information queuing, which is a middleware for asynchronous communication. Can be understood as the Post office, the sender sends the message to the Post office, then the Post office helps us to send to the specific receiver, the specific sending process and the time is irrelevant to us, the common MQ also Kafka, Activemq, Zeromq, RABBITMQ and so on.RabbitMQRABBITMQ is a follow the AMQP protoco

RABBITMQ is undoubtedly one of the most popular message queues in the world, and support for various locales is also plentiful, and it is necessary to learn and understand this tool as a. NET developer. There are about 3 usage scenarios for Message Queuing:1, system integration, the design of distributed systems. Various subsystems are connected via messages, and this solution has evolved into an architectural style, the "architecture through messagin
