> Since server side prefetching was not proved to be a good way to prefetch, we
> need to do it on client side.
> This is a wrapper class that takes any instance of `ResultScanner` as the
> underneath scanning component. The class will schedule the scanning in a
> background thread. There is a buffering queue storing prefetched results,
> whose's length is configurable. The prefetcher will release the thread if the
> queue is full and wait for results to be consumed.
