[rules-users] Stream Mode with Temporal Reasoning and Event Lifecycle Management

Hi, I'm thinking about something. Maybe anyone can tell me. The Stream Processing Mode of Drools Fusion provides automatic lifecycle managment. For my understandings this is based on the sliding windows used inside the rule conditions, the @expires metadata and the @delay metadata. Am I right so far? My questions is now: How are Events handled if non of the things listed above are used? Let's say I've got rules just using the temporal reasoning operators inside the rule conditions - no sliding windows at all. I'm also not using any of the @expires and @delay metadata. Is it correct than that: - Drools matches the event coming in and the events existing in the KnowledgeBase and eventually activates a rule. And after fireAllRules() is called the resulting actions are performed and all Events are retracted by the automatic lifecycle managment, because there are no hints (like a sliding window) that events will be needed again. (So that the knowledge base would be empty again?) Thanks for any explanations. :) Tina
