Description

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.
