> But there is another scenario that we need small scan is that, we do not know
> the stop row but we only want a small set of results. For example, in the
> implementation of region locator, we will use small scan and set caching to 1
> as we only need one row.
> So I think we need to add a new option(maybe called limit?) for the scan
> object, and deprecate the small option. And the server side modification
> should also be committed to branch-1 to simplify the logic of async client in
> 2.0.
