A recent post on the users list has led me to investigate DTs with O(10000) rows. While the sample XLS with 26,400 rows and 6 condition and 1 action columns was still manageable, a (my) system may exhibit severe memory problems when the number of rows is increased.
Test indicate that ~25,000 rows is just about manageable if you don't need lightning startup for your application - serialization doesn't help here. It would appear that Drools users are (not intentionally) led to believe that Drools' performance is immune against the usual detriments that arise from "large numbers". I think that Section 2.4., Decision Tables in Spreadsheets, should contain a warning. -W _______________________________________________ rules-dev mailing list rules-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
