      Description

      If there is an unclean leader election, a follower may have an offset out of the range of the leader. Currently, the follower will delete all its data and refetch from the smallest offset of the leader. It would be useful to add an option to let the follower refetch from the largest offset of the leader since refetching from the smallest offset may take some time.
