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

     [ https://issues.apache.org/jira/browse/MAVIBOT-40?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Emmanuel Lecharny resolved MAVIBOT-40.
--------------------------------------
    Resolution: Won't Fix

Actually, keeping those three pages separated is fine.

>            Reporter: Emmanuel Lecharny

> 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.
