> I have a table with 3 ranges,then I scan the table cross all 3 ranges.
> Scan scan = new Scan();
> scan.setCaching(10);
> scan.setFilter(new PageFilter(21));
> [result rows count = 63]
> the Result has 63 rows, each range has scaned,and locally limit to page_szie.That is expect result.
> Then if the page_size = N * caching_size, then result has only page_size rows,only the first range has scanned.
> If page_size is Multiple of caching_size,one range rsult just align fill the caching,then client NOT trrige next range scan.
> Example:
> Scan scan = new Scan();
> scan.setCaching(10);
> scan.setFilter(new PageFilter(20));
> [result rows count = 20]
