> Mainly for restart a scan when error. For now, the logic for reverse scan is not stable.
You can see the ConnectionUtils.createClosestRowBefore. we just append some 0xFF to the end
of a key. This works for most time but theoretically we could have a row between the given
row and the 'closest row before'.
> So here I propose we use a cell as the start point of a scan internally as we can use
createFirstOnRow or createLastOnRow to bettr control the restart point.
