@guyinyou By design, this is to define the reclamation policy of the default message store and kick off the reclaiming thread when free disk space is running low. The whole design is pretty similar to how [Linux manages memory](https://blogs.oracle.com/linux/post/anticipating-your-memory-needs) With that said, we may have two improvements: 1. Watermarks measured in megabytes are better than the ratio. Image, if disks with a capacity of 100G expect a much more urgent action than those with a capacity of 4T if both of them have 15% disks free; 2. Free disk watermarks of min, low, and high (in Linux kernel terms) shall be validated before getting applied, where min <= low <= high. -- This is an automated message from the Apache Git Service.
