3. Group Rebalancing及其发生的原因 **Group Rebalancing(消费者组重新平衡)**是Kafka自动将分区重新分配给消费者组中的消费者的过程。这通常发生在以下几种情况: 新的消费者加入或离开消费者组:当新的消费者加入或现有消费者离开消费者组时,Kafka需要重新分配分区以确保所有分区都被消费者组中的某个消费者处理。
@KafkaListener(groupId = "group1", topics = TOPIC, concurrency = "2") void listenForGroup1(String in) { latch1.countDown(); } @KafkaListener(groupId = "group2", topics = TOPIC/*TODO until we figure out non-relevant partitions on assignment, concurrency = "2"*/) @KafkaListener(grou...
The expected time between heartbeats to the consumer coordinator when using Kafka’s group management facilities. Heartbeats are used to ensure that the consumer’s session stays active and to facilitate rebalancing when new consumers join or leave the group. The value must be set lower thansession...
# Consumer timeout period when the Kafka consumer grouping mechanism is used. If the broker does not receive the heartbeat of the consumer within this period, the consumer will be considered to have failed and the broker will initiate the rebalancing process. Currently, the value of this parame...
一个消费者 group 由一个或者多个消费者组成,原则上每个消费者都需要有一个 groupId。这个可以在KafkaConsumer创建的时候指定。当消费者组只有一个消费者时,此时可以认为就是点对点模式;当有多个消费者时,就可以认为是发布订阅模式。 对于Broker 端的TopicPartition 而言,一个Partition 只能被一个消费者消费。也就是...
