Jonathan Gray commented on HBASE-2438:
--------------------------------------
Just wanted to clarify. This all sounds good guys. You're right, we currently
don't fully support stateful scanners as they cannot ride across regions. This
has been explored but not yet implemented.
> 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
> Original Estimate: 8h
> Remaining Estimate: 8h
>
> 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.
