kafka-消费者组-发布订阅测试

1、发布订阅测试

接着上一篇点对点博客测试
kafka-消费者组-点对点测试博客链接
多个消费者组，每个组都可以消费一次消息
消费者在不同组 就是发布订阅模式

1.1、创建消费者4并指定组 my_group2

[root@localhost ~]# kafka-console-consumer.sh --bootstrap-server 192.168.74.148:9092 --topic my_topic1 --group my_group2

1.2、列出所有的消费者组

[root@localhost ~]# kafka-consumer-groups.sh --bootstrap-server 192.168.74.148:9092 --list
my_group2
my_group1

1.3、查看 my_group2 组的详细信息

[root@localhost ~]# kafka-consumer-groups.sh --bootstrap-server 192.168.74.148:9092 --group my_group2 --describe

GROUP           TOPIC           PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             CONSUMER-ID                                               HOST            CLIENT-ID
my_group2       my_topic1       0          2               2               0               consumer-my_group2-1-a101354d-34f8-4d3a-83e2-95b4edcab830 /192.168.74.148 consumer-my_group2-1
my_group2       my_topic1       1          1               1               0               consumer-my_group2-1-a101354d-34f8-4d3a-83e2-95b4edcab830 /192.168.74.148 consumer-my_group2-1
my_group2       my_topic1       2          2               2               0               consumer-my_group2-1-a101354d-34f8-4d3a-83e2-95b4edcab830 /192.168.74.148 consumer-my_group2-1
