As far as i've read in the documentation, creating statefulKnowledgeSession's is cheap, even though reading the rulebase is not. And you can even persist your sessions in database, so i'd say that's not too much to worry about

But i'm a newbie, more experienced users may disagree.

Hi everyone,

I'm trying to find a solution to the following situation:

- KnowledgeBase with approx. 1000 rules
- Approx. 200 users (hence 200 simultaneous sessions) whereas each session
might most likely have different values for the working memory facts

So let's say we create a KnowledgeBase (with those 1000 rules) and out of
this one KnowledgeBase we create for each existing session its own
StatefulKnowledgeSession.
Now, how expensive (memory-wise) are these StatefulKnowledgeSessions? Is it
reasonable to have more than just a few StatefulKnowledgeSessions?
Or is there an other, better approach?

Thank you very much!
