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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
