Hi Avishek Das: Though I am not sure about your issue. but I encounter the similar issue and fix it with:
https://github.com/apache/kafka/pull/20007 https://github.com/apache/kafka/pull/20203 https://cwiki.apache.org/confluence/x/Hg9JFg You can refer to it to see if it is the same issue. thanks Regards Jian Avishek Das via users <[email protected]> 于2026年2月16日周一 21:32写道： > Hello Team, > > During tiered storage performance testing on Kafka 3.9.1, we observed cases > where a broker did not trigger scheduled RLMCopy tasks, resulting in no > segment uploads to remote storage.
