1. 理解RocketMQ消费者偏移量(Offset)的概念 在RocketMQ中,每个消费者组(Consumer Group)对其订阅的每个主题(Topic)下的每个消息队列(MessageQueue)都有一个消费偏移量(Offset)。这个偏移量记录了消费者下一次拉取消息的位置。 2. 确定需要重置偏移量的原因和目标位置 在重置偏移量之前,我们需要明确重置的原因和目标...

Reset a consumer offset to clear accumulated messages or roll back consumption,ApsaraMQ for RocketMQ:If you reset a consumer offset, the offset from which a consumer starts to consume messages is changed. If faults occur or wrong messages are consumed du
new ActiveMQQueue("TEST.QUEUE?consumer.exclusive=true"); 1. 如果有2个consumer都是这样配置的,broker只会把队列消息发送给其中一个consumer,如果这个consumer挂掉了,broker会把消息推送给另外的consumer,这样就保证了按顺序消费消息。 那么,ActiveMQ是怎样实现这种逻辑的呢?
暂无变更历史 控制台操作 除了调用 OnsConsumerResetOffset 接口,您还可以通过云消息队列 RocketMQ 版控制台重置指定 Group ID 的消费位点。具体操作,请参见重置消费位点。 上一篇:OnsConsumerGetConnection - 查询Group ID客户端连接情况下一篇:OnsConsumerTimeSpan - 查询Topic可重置时间范围 ...
Consumer作为ActiveMQ的消费端,看起来简单,不过还有很多隐藏的特性,值得我们去探索和调优。 如下为典型的Consumer端代码示例 String brokerUrl = "tcp://localhost:61616?" String queueName = "test-queue"; ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(brokerUrl); ...
