一般来说消息堆积是由于生产消息的速率远大于消费消息的速率所导致的。比如某个时间段消费端处理消息异常缓慢，发送一条消息只要3秒钟，而消费一条消息需要1分钟，每分钟发送20个消息，只有一个消息被消费端处理，这样队列中就会产生大量的消息堆积。 消费者出现异常，生产者一直在发送消息，但是消费者不能消费，造成消息积压。
Consumer）表示队列中可以注册多个消费者，但是只允许一个消费者消费消息，只有在此消费者出现异常时，才会自动转移到另一个消费者进行消费。单一活跃消费者适用于需要保证消息消费顺序性，同时提供高可靠能力的场景。 如图1所示，Producer生产9条消息，由于队列设置了单一活跃消费者特性，只有Consumer
对消费者进行流控的方法。 设置预取值时，需要考虑多种因素： 预取值设置太小可能会损害性能，RabbitMQ会一直在等待获得发送消息的权限。 预取值设置太大可能会导致从队列中取出大量消息传递给一个消费者，而使其他消费者处于空闲状态。另外还需要考虑消费者的配置，消费者在处理消息时会将
