Subject [jira] [Created] (ACCUMULO-1639) Server-side iterator/filter that allows you to specify a lexicographical range of column qualifier values you want to retrieve from a Scanner (ColumnSliceFilter)

Jeffrey Principe created ACCUMULO-1639:
------------------------------------------

             Summary: Server-side iterator/filter that allows you to specify a lexicographical
range of column qualifier values you want to retrieve from a Scanner (ColumnSliceFilter)
                 Key: ACCUMULO-1639
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1639
             Project: Accumulo
          Issue Type: New Feature
    Affects Versions: 1.5.0, 1.4.3, 1.4.4, 1.5.1, 1.6.0
         Environment: All
            Reporter: Jeffrey Principe
            Priority: Minor


This filter is modeled off of the RegExFilter class in the org.apache.accumulo.core.iterators.user
package. It allows you to specify a lexicographical start and end (including whether or not
it is inclusive on each side) to a range of column qualifier keys that you would like returned
from the retrieved data set on a Scanner or BatchScanner. It sets options on its IteratorSetting
with a static method (setSlice), and is added to a Scanner/BatchScanner using addScanIterator
like normal iterators/filters. This filter is intended to be an Accumulo equivalent to HBase's
ColumnRangeFilter.
