Reid Chan updated HBASE-29238:
------------------------------
Description:
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.
was:
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.
