> [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
> Assignee: Wes McKinney
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.8.0
>
>
> 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.
