It's cool to see different approaches to Rete in Clojure. I think a solid implementation could really disrupt Drools. Why would I want to write in a limited rule language if I can get rule-like semantics and the expressiveness of Clojure at the same time? Of course I'm going to be biased towards Clara, but more important is the fact that Clojure provides a stronger foundation for expert systems than anything else out there. This is an opportunity for Clojure to make inroads.
Regarding the benchmarking questions, I'm sure Drools will run Ms. Manners and other benchmarks faster than Clara at this point. This is partially because I've emphasized correctness and simplicity in Clara first, although I've recently started doing some significant profiling and optimizations. But Ms. Manners is really a poor example of typical rule engine use...it was created specifically to exercise some worst case scenarios. It's also constraint-oriented, so I'd actually use core.logic to solve that problem before I'd use any forward-chaining approach. More important is to ask whether a system is fast enough for your needs. I gladly pay some overhead for persistent data structures because they are fast enough and save me a lot of time. (And I can spend that time optimizing the real bottlenecks of the program!) These advantages tend to pay off in surprising ways, such as the recent excitement around how fast React and Om are. Clara will get optimized, but not at the cost of Clojure ideals like immutability. In any case, it's great to see activity around Rete in Clojure. Clara was designed for a particular problem space I've been working in, but it's certainly not the only approach we should consider. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
