Thanks for this @Luca. Can drools be used for transaction rules where you can have multiple rules for one decision, that is Approve or Decline transaction if a percentage of these hundreds of rules are true or false? how do you set that in DRL engine?

28:44 I tried the exact same rule 30 times and compared the execution time it didn't optimise, in fact the more times I repeat the same rule the more it takes to execute linearly

I have one doubt.. is it possible that if we update drl file so without restart server will it reflect. I tried but not working. Spring dev tools dependency is not feasible solution.
