Jonathan Gray commented on HBASE-2438:
--------------------------------------
Patch looks good, just some nitpicks.
- Take out cleanup changes made to TestSingleColumnValueFilter (your patch
otherwise does not touch this file so doesn't belong in this patch)
- TestColumnPaginationFilter has a copyright header from your company. This
should be removed and replaced with the apache license.
- ColumnPaginationFilter should be given an apache copyright header as well.
Otherwise, this looks good. Haven't run unit tests yet but will try to get to
that tonight.
Good stuff Paul.

> 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.
