> Some quick comments. I'm still trying to understand how the disk io stats get considered. Some documentation would be helpful. > > Instead of being part of AvailableSpaceVolumeChoosingPolicy, would it make sense to become a new volume choosing policy? Thanks @jojochuang for your comments, I will add documentation and update the code. When doing the POC testing, we define a new policy, named `IOUtilVolumeChoosingPolicy`, only considering the ioutils without considering the disk space usage, it will cause uneven disk utilization. So we change AvailableSpaceVolumeChoosingPolicy, under the same disk usage, preferred ioutils smaller disks, filtering the busy disks. What you said about offering a new policy is a good idea. -- This is an automated message from the Apache Git Service.
