[jira] [Created] (MAVIBOT-40) We could probably merge the BTreeHeader page and the Root Page

----------------------------------------

             Summary: We could probably merge the BTreeHeader page and the Root Page
                 Key: MAVIBOT-40
                 URL: https://issues.apache.org/jira/browse/MAVIBOT-40
             Project: Mavibot
          Issue Type: Improvement
    Affects Versions: 1.0.0-M4
            Reporter: Emmanuel Lecharny
            Assignee: Emmanuel Lecharny
            Priority: Minor


Currently, each BTree has at least 3 pages :
- BTreeHeader
- BTreeInfo
- RootPage

As we copy the BTreeHeader and the RootPage for each modification, we could probably merge them into one single page. That would save one update on disk.
