I assume you need all 1 billion facts in WM at once?<br><br>i.e. event processing\CEP\streaming isn't more suitable?<br><br><div class="gmail_quote">On 8 September 2010 16:31, bellios <span dir="ltr"><<a href="mailto:carfid@gmail.com">carfid@gmail.com</a>></span> wrote:<br>

Hi all,<br>
i have read the Documentation and the Drools book. I am developping an<br>
application but i don't understand in my case how i can loading a<br>
1,000,000,000 facts (approx).<br>
At present I load all facts into a StatefulKnowledgeSession with a for-<br>
cycle and I insert them into ksession ("ksession.insert(customer);")<br>
<br>
The problem is the out of memory exception due the high memory<br>
requirements of facts.<br>
How i can resolve it? There is another approach to<br>
facts loading into session? Can i integrate the loading with JPA/Hibernate<br>
frameworks?<br>
<br>
Thanks in advance for any suggestion,<br>
David<br>
