There's one thing I would like to point out about drools 5, which should cause concern for users. The "new" asymmetrical Rete feature is a big mistake in my mind. It is equivalent to telling users "go ahead and modify the database file directly and by pass the database." Clearly, that is wrong and violates well established transaction theory and practice. I've tried my best to convince drools to go with a simpler approach, which gives users the option of telling the engine which facts should be shadowed. The current drools api has insert(Object).   The simpler solution is to add a new method insert(Object, boolean shadowed). This is more flexible and gives users the choice. Plus, it doesn't violate transaction principles. I know mark has been hyping asymmetrical for almost a year now. As far as I'm concerned, it's a step backwards for rule engines. Having said that, I think the over all suite is still solid and users should continue to use it. I still recommend it to developers who ask me. I caution people not to use the new asymmetric feature.
