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

[Tina Vießmann]

  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
