To purge the Kafka topic, you need to change the retention time of that topic. The default retention time is 168 hours, i.e. 7 days. So, you have to change the retention time to 1 second, after which the messages from the topic will be deleted. Then, you can go ahead and change the retention time of the topic back to 168 hours.

之前有个 Kafka 集群的每个节点的挂载磁盘多达 20+ 个，平均每个磁盘约1T，每个节点的分区日志被平均分配到这些磁盘中，但由于每个分区的数据不一致，而集群节点 log.retention.bytes 这个参数的默认值是 -1，也就是没有任何限制，因此 Kafka 的日志删除日志依赖 log.retentio Kafka can serve as a kind of external commit-log for a distributed system.
