Paul Kist commented on HBASE-2438:
----------------------------------
Jonathan, I made the suggested changes, as it would allow for a more generic
use of the Filter. Also, I added a unit test "TestColumnPaginationFilter"
which basically tests the serialization and performs a simple filter example
(since most of the filter testing is in the TestFilters unit test class. Will
post the patch

> 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.
