For those who integrated drools on GAE, can you please give some feedback on - the memory consumption (does it work with a F1 instance)? - startup time (initialization of KnowledgeBase) - do you serialize your KnowledgeBase objects to datastore? - do they fit in 1MB blobs? And more generally, I'd like to know if it's a good idea to use drools on gae also asked on http://stackoverflow.com/questions/23626451/does-drools-work-well-on-goog... Best Regards, Zied Hamdi
