Re: [rules-users] Loading facts and memory size limits
That seems a lot of facts, are you sure you really need that many facts in your knowledge
session?
What are you actually trying to achieve? Do you really need all of the facts in memory at
once?
Ignoring drools are you actually able to load them up into your JVM at all?

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