Re: [rules-users] Simple aggregation problem

Raja, it is not clear what you are trying to achieve. The rule might be well written or not, we don't know your requirements. If "id" is what it should be - an identifier - your accumulate constraint would match a single object for each Product (the original product itself), which looks suspicious. I'll assume that you are doing a performance test and you are not satisfied with the overall execution time. The question, however, is: how many facts are you inserting? Are you firing all rules after the insertion of each fact, or just once at the end? Last, but not least, which version are you using? Accumulate should be used carefully in combination with insertLogical, since the former updates its result every time its fact collection changes. The latter will generate a new fact, keep track of its dependencies, and replace it when the accumulation result itself changes. Of course, if you were inserting 100 facts, the numbers would raise a warning, but could be reasonable for several thousands, if not hundred thousands. Citing one of your previous emails: "I want to test my rules with 10,000 facts to 20,000,000 facts" Best Davide On 03/03/2014 12:10 PM, Raja Sekhar wrote:
