例如 Consumer Group A 订阅了 Topic A,Consumer Group B也订阅了Topic A,则发送到Topic A的每条消息,不仅会传一份给Consumer Group A的消费实例,也会传一份给Consumer Group B的消费实例,且这两个过程相互独立,相互没有任何影响。 一个Consumer Group 对应一个应用 建议一个 Consumer Group 对应一个应用,即不...
CreateConsumerGroup - 创建消费组,云消息队列 Kafka 版:调用CreateConsumerGroup创建Group。 下表是API对应的授权信息,可以在RAM权限策略语句的Action元素中使用,用来给RAM用户或RAM角色授予调用此API的权限。具体说明如下:
has a 'Group Id' contains multiple consumer instances consumers work together to consume the Topics 1 partition could be consumed ONLY by 1 consumer example if we have 3 Topics A, B, C and they have 1, 2, 3 partitions respectively, how many conusmer instances should we create?
processRecords(consumer); }privatestaticKafkaConsumer<String, String>createConsumer() { Properties props=newProperties(); props.put("bootstrap.servers","localhost:9092"); String consumeGroup="cg1"; props.put("group.id", consumeGroup);//Set this property, if auto commit should happen.props.put...
To summarize, you create a new consumer group for each application that needs all the messages from one or more topics. You add consumers to an existing consumer group to scale the reading and processing of messages from the topics, so each additional consumer in a group will only get a su...
