从 kafka 主题 __consumer_offsets 中删除特定消息

Question

I want to delete all messages that are contained in the __consumer_offsets table that start with a given key (resetting one particular consumer group without affecting the rest).

Is there a way to do this?

Answer 1

Kafka comes with a ConsumerGroupCommand tool. You cand find some information in the Kafka documentation .

If you plan to reset a particular Consumer Group ("myConsumerGroup") without affecting the rest you can use

> bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --reset-offsets --group myConsumerGroup --topic topic1 --to-latest

Depending on your requirement you can reset the offsets for each partition of the topic with that tool. The help function or documentation explain the options.
