This problem used to be one of the popular benchmarks for rule engines 20 years ago. And now DMCommunity.org brings it back to see how modern decision engines can represent and solve this problem today. I will demonstrate it in this post with the latest OpenRules Rule Solver.

Our customers frequently select OpenRules for their decision management needs because of two important factors: 1) Ease of Use; and 2) Performance and Scalability. We have large customers who use OpenRules to create very complex decision models capable to handle large payloads – see an example with 17M records.
Recently we received a request to create a decision service capable to handle 1B records. Luckily this large corporation already uses Apache Spark for scalable computing as thousands of other companies, including 80% of the Fortune 500.
Within a few days, our team built a POC that put an OpenRules-based decision service inside an Apache Spark application. The performance results were really impressive: the total execution time for 1 billion records was under 7 minutes averaging 2.5 million decisions per second! Read more in the new manual “OpenRules-Spark Integration“.
When we converted a POC into a real decision service that handles more than 30,000 complex rules, we received the following execution results:
For years OpenRules was among the fastest rule engines. When last year we moved from run-time interpretation to design-time code generation, we, like our colleagues at Red Hat Drools, managed to further improve the overall performance and provide support for practical decision microservices. As a result, we dramatically minimized start-up time, went from 50-100 milliseconds per transaction to 5-10 milliseconds, made memory footprint small. These are really good results needed by modern enterprise decision-making systems.
However, I knew that we have multi-year customers that use really big (!) decision tables with 10 and even 30 thousands of rules. How to improve their performance? Continue reading
