Re: [rules-users] Rule processing for High volume input
Thanks Greg. Since I'll do update on the facts to control the order of
execution, I don't think i can go for sequential mode.
1. I can't have multiple session from same rulebase and assign each session
to single thread. right?
2. Can I use drools 5 in production environment? if not, when is first prod
release expected?
3. where can I do look for rule base partitioning examples/info?

I'm assuming you'll be running each rule base in a separate thread
simultaneously? There are no dependencies between the rules in the five
rule bases? If so, that will work just fine.
If your rules are simple enough you can use sequential mode. It can speed
up execution quite a bit.
http://downloads.jboss.com/drools/docs/4.0.7.19894.GA/html_single/index.h...
This could be used in conjunction with the simultaneous execution above.
Finally, you can get some multithreaded benefit in a single rule session
if you're using drools 5 and turn on rule base partitioning. As I
understand it this works best when the rules have less join conditions in
them. (i.e. mostly single object conditions, and less multi-object
conditions.)
