[esb-issues] [JBoss JIRA] Reopened: (JBESB-2830) Add Stream Mode support to BusinessRulesProcessor

Add Stream Mode support to BusinessRulesProcessor ------------------------------------------------- Key: JBESB-2830 URL: https://jira.jboss.org/browse/JBESB-2830 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Jeff DeLong Assignee: David Ward Fix For: 4.9 The BusinessRulesProcessor should support configuration for "StreamMode" with StatelessKnowledgeSessions. Most CEP applications will require StreamMode to enable sliding window support, garbage collection of expired facts, etc. This is really important (a necessity), and is turned on through the API. This would require configuration such as <action class="org.jboss.soa.esb.actions.BusinessRulesProcessor" name="OrderCountHistory"> <property name="ruleSet" value="OrderCount.drl"/> <property name="ruleReload" value="true"/> <property name="stateful" value="true"/> <property name="vventProcessingOption " value="STREAM"/> The code to use this would be something like: kconfig = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); kconfig.setOption( EventProcessingOption.STREAM ); kbase = readKnowledgeBase(kconfig); sconfig = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(); sconfig.setOption( ClockTypeOption.get( ClockType.REALTIME_CLOCK.getId() ) ); ksession = kbase.newStatefulKnowledgeSession(sconfig, null);
