[jira] Created: (HBASE-2438) Addition of a Column Pagination Filter

Addition of a Column Pagination Filter
--------------------------------------

                 Key: HBASE-2438
                 URL: https://issues.apache.org/jira/browse/HBASE-2438
             Project: Hadoop HBase
          Issue Type: New Feature
          Components: filters
    Affects Versions: 0.20.3
            Reporter: Paul Kist
             Fix For: 0.20.3


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.
