> 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.
