Subject Re: Retrieving Multiple Revisions
Date Thu, 02 Feb 2012 23:40:28 GMT
Hi jon,

its not a good idea to rely on document revisions, they are prune on compaction, you have
to create your own new documents if you want to implement versioning and stuff. i think its
generally a bad idea to  do it that way. you can also create just one document per user and
merge their posts in a view for the chat. the app itself could use the _changes feed.

thx
mario
