> If storage policy is unspecified, the default is either HOT or DISK.
> In our production case, we have a cluster which support DISK in A IDC while SSD only in B IDC (yes, it is cross-IDC cluster).
> We want to export a snapshot to B IDC using all SSD directly, but since default policy, it will be DISK. We have to trigger a major compaction to move all data from DISK to SSD which it is time consuming.
> That's the background of this improvement.
