CONSUME_FROM_LAST_OFFSET issue

hi budies,
i have a new consumer group, and set ConsumeFromWhere=CONSUME_FROM_LAST_OFFSET.
hope it would consume from the last offset that other old consumer group did. but offset=0 alway i got, dont ignore historical messages, 
client code getting offset:



broker get the offset request,


ConsumeFromWhere

When a new Consumer Group is established, it will need to decide whether it needs to consume the historical messages which had already existed in the Broker. CONSUME_FROM_LAST_OFFSET will ignore the historical messages, and consume anything produced after that. CONSUME_FROM_FIRST_OFFSET will consume every message existed in the Broker. You can also use CONSUME_FROM_TIMESTAMP to consume messages produced after the specified timestamp.

萨尔卡你好,

每个Consumer Group之间的Offset都是独立的. 新的Consumer Group如果想从另一个Consumer Group的Offset开始, 可以使用cloneGroupOffset这个命令, 运维的方式设置.

使用方法, 可以通过 bash mqadmin cloneGroupOffset -h方式获得.

祝使用愉快.
