[rules-users] Drools response time
Dear all, I need to develop an Expert System for a new project and I want to use Drools, butI have some restrictions. The most important restriction: response time of the application must be less than one second. Also, the application access to one data base to retrieve some information and send it to the expert systetm. With this information, can anyone tell me, approximately, the response time of Drools? It is very important to can use Drools in this project. And we like very much to use it. (We use in other projects without these restrictions). Thank in advance. Best regards, Jesús. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools response time
Hi Jesus, Well do you want us to include the response time for your Database? The Drools Rule engine will keep all your facts inside the main memory (RAM) so it will be fast, but if you need to retrieve data from your database, you will need to take that into account. Depending on how you are doing that and how much data do you want to bring will be the response times.

If it is a hard requirement to have timely responses, you'll have to buy a real-time JRE from some commercial vendor.
