             Summary: Add null count member to Array containers, remove 
nullable member
                 Key: ARROW-20
                 URL: https://issues.apache.org/jira/browse/ARROW-20
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney


Nullability/non-nullability may become a property of the metadata (if at all, 
TBD based on implementation-wide discussions); in the meantime the array 
containers and associated algorithms will be simplified.
