[rules-users] Order of columns and of constraints

Does the order of columns in the rule definition, and the order of constraints within a column matter? For a given rule, I know which test is most likely to fail, and (probably) which one is most "expensive" in terms of processing time (eg. 'someCollection contains $var' is more expensive than 'field == "literal"'). I'd like to put the fail-fast tests up front, and the expensive ones last. Does that actually work in Drools? Can I "optimize" my rules by juggling the order of the columns and constraints? -- Dirk Bergstrom dirk(a)juniper.net _____________________________________________ Juniper Networks Inc., Computer Geek Tel: 408.745.3182 Fax: 408.745.8905
