> 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.
