> Now for the AsyncResultScanner, we can only close the scanner if we reach the
> cache size limit and open a new scanner later. This will breaks the region
> level consistency.
> For example, you put 10 rows to the region, and open a scanner to scan it.
> The scanner returns 5 rows at the first time and the cache is full, so it
> closes the background scanner. And before you reopens the scanner to fetch
> data, the remaining 5 rows has been deleted and a compaction makes them gone
> for ever. Then after you reopen the scanner you can not see the remaining 5
> rows.
> So here we should keep the scanner open at RS side to prevent the data below
> the mvcc read point of this scanner being deleted.
