Hi again,
I have collect some more information regarding the problem I mentioned in my
previous post. I take a thread dump during the compilation process and as I
can see the thread that makes the compilation is the following:

I am trying to run a partitioned rule base as we have a need to evaluate a
large number of facts. We have around 160 rules which are coordinated using
jBPM rule-flow groups(intermingled with some lightweight business logic).
The business logic in the process executed quickly(80ms for 10,000 facts)

Dear Mauricio and Anton and others,
thanks again for your interest.

Hi all,
i have a big problem with drools fusion.
I insert some new event (pojo object) into Working Memory, but another
thread retract it after a few ms.
Someone could tell me why?
Thanks a lot,

Why are you trying with that partitioning approach?
By the why I notice that most of the time when people uses ruleflow-groups
they didn't realize that all the evaluations are done at insertion time,
not when the process reaches the rule flow group, is that you case?
Doing consulting around these
I understand that all the evaluations are happening at insertion time. The
main reason for the groups is to intermix logic needed to execute outside of
rules(i.e I don't want rules invoking DAO's to retrieve data). I am trying
to partition because I need to be able to get a high level of messages

So the question is.. for processing those messages, you can set up multiple
sessions and evaluate each message separately?
or do you need to have all the messages in the same session?
Cheers

Executions need to happen in an order based on a data and a message id(at
least at one part of the evaluation). Because of this my plan was to use
dynamic salience and insert as many of the facts as I can at a time

But are the facts related with each other? do you need to analyze them all

Can you share a little bit more about your use cases? What do you mean with
Execution execution of what? What do you mean with evaluation?

We are writing a billing system using Drools to evaluate orders placed during
the day(this is a month to date process which will run nightly and we will
be bringing a real-time solution online later this year after we rewrite the
existing). Base fees of these orders can happen in parallel and in

of your data, chose the number of partitions, create a kbase per
partition and then hash on your inserted data to get the target kbase.

Drools doesn't partition. You will need to build an external framework
that partitions your data, and then assign a ksession per parition.
Whether it's a ksession or kbase per partition depends on whether you
can use the same rules per partition or not.

Additionally when does partitioning by data cause performance to be
compromised? It has always been in my experience and to my knowledge that
building a complete session with facts is cheaper then iterating a list of
facts, creating a session, and firing. Perhaps I am mistaken? Additionally

We also ran into similar memory issues. Some object references are not being
released. We load around 10,000 rules from different excels. When we reload

by 50%. It kept on increasing for each load and finally throws Out

I have a use case where I am executing a BatchExecutionCommand against a
stateless session. One of the sub-commands is a FireAllRulesCommand, from
which I would like to retrieve the number of rules actually fired. Since
there is no factory or constructor method to configure
I was thinking we could do separate sessions then queue up the results in
order and process themI also like Mark's idea of partitioning

i think that have to study more in deed some manuals, because there are
some aspects not very clear, in particular the threads behavior.
For example, i have a class running in a container (thread A) that launch
