[rules-users] Persistence & Clustering

Hi, I have started to look at drools and I had the following questions. Apologies if that is in the doc or in the archives of the mail group, but I did not find any answer. 1) Is there some support (is it a valid question?) for the persistence of the working memory and state of the engine? Or is it easier to just reassert all objects ? 2) Is there any support to grid/cluster the engine? Can the working memory use a distributed cache ? Best Regards, -- Jean Safar
