-----------------------------------
The failed UT of branch-1 is not related. But seems it fails consistently. Will
open another issue to fix it.
Will commit shortly.

> For the current implementation, if we use batch or allowPartial when scan,
> then the row level atomic can not be guaranteed if we need to restart a scan
> in the middle of a record due to region move or something else.
> We can return the mvcc used to open scanner to client and client could use
> this mvcc to restart a scan to get row level atomic.
