>> This assumes the key is always sorted. Is it true?
Pagination is be numbers, e.g. get 10 rows starting from number 100 or getRows(100, 10). Column family uses KeyRange to get a section of the table. This assumes the key is always sorted. Is it true? Secondly, the key normally a string. How do you translate the starting row number to a string key? You can start from row 0 until row 100 and then collect 10 rows. This may not be efficient. Is there a better way to paginate through CF?
