[xwiki-devs] read-only XWiki ?

Hello list, I have had a short attempt: set GLOBAL read_only=true; on the MySQL that runs my curriki and it kind of works. A few exceptions are thrown at the beginning but otherwise it seems to render well. The interest is that it could allow some of the web requests to be served by a database that is a slave of the main database, in live synchronization with the master MySQL. Has anyone tried that? thanks in advance paul
