    Description

      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.
