TCP Keepalives。 一些客户端(如C语言客户端)没有发送心跳的逻辑,即使配置了心跳超时时间,开启了心跳,仍然无法发送心跳。此时需要额外启动一个线程,编写发送心跳的逻辑。 LVS的心跳超时时间 RabbitMQ集群实例使用LVS进行负载均衡,如图1所示,单节点实例不涉及LVS。

华为云使用RabbitMQ作为消息引擎,RabbitMQ是一个生产者和消费者模型,主要负责接收、存储和转发消息。以下概念基于RabbitMQ进行描述。 消息 消息一般分为两部分,消息体和标签,标签主要用来描述这条消息,消息体是消息的内容,是一个JSON体或者数据等。 生产者发送消息
Active 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

最终的处理结果都是一致的,避免了因消息重复而对业务产生影响。 例如在支付场景下,用户购买商品后进行支付,由于网络不稳定导致用户收到多次扣款请求,导致重复扣款。但实际上扣款业务只应进行一次,商家也只应产生一条订单流水。这时候使用消息幂等就可以避免这个问题。 在实际应用中,导致消息
者中未被确认的消息数量达到设置的预取值,服务端将不再向此消费者发送消息,除非至少有一个未被确认的消息被确认。设置预取值本质上是一种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
