Re: [rules-users] Drools Fusion speedup

[PF]

Hi Mauricio,
We are using Drools Fusion. However, the classes from the example that you
mentioned in your previous post (
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-examples/drools-examples-fusion)
are not documented in the documentation (org.drools.time.Trigger and
org.drools.time.TimerService are not mentioned in the documentation:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-fusion/html_single/index.html).
The events that we are creating have the role "event" and they are matched
with the rules which are written in Fusion using the temporal reasoning
enabling operators. To get the comlex events feedback (printouts), please
uncomment the "println" statements in the "then" part in the fusion.drl
(rule file), these were commented out to get better results in the
benchmarks.
I attached the sources in this email.

BTW: We have a second question regarding aggregate functions (count, sum,
etc.). Does Drools Fusion provides any kind of aggregates over events or
these should be created separately in the .drl file (as rules)? We cannot
find anything like that in the documentation.
Regards,
Paul Fodor.
