["Jacky.J.Wang (mis.cnxa01.Newegg) 43048" <Ja...@newegg.com.INVALID>]

Hello kafka

I truncate data of kafka as follow

1：stop kafka service
2：delete zookeeper /broker/topics/topic and /consumers/group
3：delete kafka log dir
4：restart kafka service
5：recreate topic info
but this way need to stop the service，so how truncate kafka topic data with no stopping kafka service？

Eagerly awaiting your reply，thanks

Hi Jacky,

Could you elaborate a bit on your use cases, like why you want to manually
truncate logs? Kafka provide a set of configs for data retention based on
data size and time (for example maintaining as much as 100 GB or up to 7
days of old data), would that be sufficient to you?
