Description
The following two rulesets produce the same output, but their performance differs dramatically.
My understanding is that the two rulesets should be equivalent to one another. It seems like the 'or' operation must be handled inefficiently by the engine. Is there anything that can be improved the engine's performance in this case?
Ruleset #1 takes ~3 seconds to execute on my local machine (for a dataset with 3 entities, 1 service ordered each). Ruleset #2 runs in ~200 ms.
Ruleset 1
rule "Rule183" dialect "mvel" when $entity : Entity( ) ( $service : ServiceOrdered( serviceId == "FORM" , entity == $entity , entity.entityTypeId in ( 291262, 291275, 291277 ) ) or $service : ServiceOrdered( serviceId == "DISSO" , entity == $entity , entity.entityTypeId in ( 291262 ) , stateId == 290864 ) ) $r1 : QuestionDefinition( id == 590 ) then Question fact0 = new Question(); fact0.setQuestionDefinition( $r1 ); fact0.setEntity( $entity ); insert( fact0 ); end
Ruleset 2
rule "Rule183" dialect "mvel" when $entity : Entity( ) $service : ServiceOrdered( serviceId == "FORM" , entity == $entity , entity.entityTypeId in ( 291262, 291275, 291277 ) ) $r1 : QuestionDefinition( id == 590 ) then Question fact0 = new Question(); fact0.setQuestionDefinition( $r1 ); fact0.setEntity( $entity ); insert( fact0 ); end
rule "Rule183-2" dialect "mvel" when $entity : Entity( ) $service : ServiceOrdered( serviceId == "DISSO" , entity == $entity , entity.entityTypeId == 291262 , stateId == 290864 ) $r1 : QuestionDefinition( id == 590 ) then Question fact0 = new Question(); fact0.setQuestionDefinition( $r1 ); fact0.setEntity( $entity ); insert( fact0 ); end
