Optional SortedMap semantics for matching ----------------------------------------- Key: DROOLS-676 URL: https://issues.jboss.org/browse/DROOLS-676 Project: Drools Issue Type: Feature Request Affects Versions: 6.2.0.CR3 Environment: any Reporter: Paul Houle Assignee: Mario Fusco Original Estimate: 4 weeks Remaining Estimate: 4 weeks Drools uses a Map instead of a SortedMap to accelerate the matching of patterns that have an equality relationship. Performance-wise this is the right decision most of the time, but if one wanted to accelerate matching of patterns such as Person(age > 100) having a sorted index could be beneficial. In a case like that the object in question must implement Comparable or be associated with a Comparator. This behavior could be turned on for a particular field with @-annotation in either the DRL or Java file.
