Hi 赵科, Currently, RocketMQ uses mincore system call to determine if the message data is in memory or swapped out. It seems more reliable than judging hot and cold data based on the maintenance experience described in your proposal. And turning off read-ahead for old CommitLog is a good idea, looking forward to your progress!
Your response would be highly appreciated.

Now the i...@foxmail.com is willing to support the RIP, so I think it is time to start an email thread to enter the voting process. The vote will be open for at least 72 hours or until a necessary number of votes are reached.
