如何重置偏移值重新读取kafka主题

Question

There is a situation when Consumer1 reads messages from a kafka topic. When connecting the second Consumer2 with the same groupId , there is a rebalance of partitions. Is it possible to somehow reset the offset , so that after the rebalance process, both Consumers read the topic from the beginning?

Answer 1

I think as per your requirement you can set the offset value as Earliest , so that it can consumed from beginning.
