Sequential execution means no inference and in general rules are
executed in the order defined in the rule engine. We have this now.
Drools 5.0 will also add JIT for this, to improve performance further.
Look in the manual for details on sequential mode.

I found the following thread searching through the Drools mailing

archives and I was wondering if there were any interesting
developments to mention about sequential rules execution since it was
posted last year. I am achieving sequential execution by preprocessing
rules into activation groups and generating transfer rules to move
between groups, but I imagine my performance is much worse than it
could be.

I'm interested in sequential execution not for performance reasons but
for the simplicity it offers some users in writing their rules. A
rules engine and the RETE algorithm is too advanced for some users and
a sequential engine allows these users to author rules that will run
in a well-understood environment and protects them from infinite rule
execution, for example.
Is there any plan to offer a sequential execution mode in Drools? Does
anyone else have a similar interest?
