[rules-users] Retrieving facts from a database

Hi all, I've been lurking on this alias for a while but I have not seen any questions about this so I thought I would ask... Our application is DB intensive with potentially millions of rows in certain tables. Currently, we are testing Drools in our app with small data sets that can easily be loaded into Java heap memory, but we are concerned about the scalability of our design. My question is: Does Drools support a mechanism to dynamically load pages of facts into the working memory? Or do you have to load *all* facts in at one time as we are currently doing it? Any pointers (especially to web pages or documentation) would be appreciated. Thanks, Bryan
