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?
