[jira] [Created] (ARROW-1409) [Format] Use for "page" attribute in Buffer in metadata

Wes McKinney created ARROW-1409:
-----------------------------------

             Summary: [Format] Use for "page" attribute in Buffer in metadata
                 Key: ARROW-1409
                 URL: https://issues.apache.org/jira/browse/ARROW-1409
             Project: Apache Arrow
          Issue Type: Bug
          Components: Format
            Reporter: Wes McKinney
             Fix For: 1.0.0


This attribute is currently unused in any Arrow implementation. I think the original idea is that the "page" might indicate a particular shared memory page, so that a record batch could be spread across multiple memory regions.

The downside of this unused attribute is that Buffer metadata takes 24 bytes instead of 16 due to padding.
