> Client applications may need to do pagination, depending on the number of columns returned, it may be more efficient to perform pagination algorithms at the database level (similar to SQL's LIMIT and OFFSET).  This will be an additional filter taking two parameters:
> - page
> - pageSize
> For every row, that gets returned, only a subset of columns are returned based on page and pageSize
> If the page / pageSize column goes over the limits, then no results are returned from the filter.
> A practical example for using a filter like this may be for folks doing Row-based indexing with Hbase.
