Hi drizzle.zk, Currently, we have a precise way to find out cold data, please see https://github.com/apache/rocketmq/issues/5837. And I agree with you that we should stop prefetch CommitLog if it is not the latest file. Maybe we can use madvise system call and MADV_FREE or MADV_DONTNEED flag.
Your response would be highly appreciated.
