Hi,
I have similar requirements as Mauro in that we want all facts to be shared
across multiple drools servers in the cluster. Does anybody have this
working with Infinispan or any other framework? Since Infinispan is provided
as a service in JBoss AS 7, are there any plans for drools server to
Hi,
as an alternative, would it be possible to have several independent nodes
persisting their sessions into a remote and shared database, thus a third
listener application would load the database content in memory as an
entire session, combining all persisted sessions?
Is there an out-of-the
Not as a realtime working memory. And don't even think about persisting these
things to a database if you're trying to process high volumes of events with
minimal latency. I'm assuming that you're trying to process high volumes of
events, and you're experiencing performance problems, because
Steve,
the system is not implemented yet, but that's what I'm worried about, you're
right.
I'll take a look at CEP and distributed queues.. haven't thought of that
before.
Moreover, does Drools provide any failover solution?
Thanks for the light!!

With regards failover, there is session persistence, but you won't have a 'hot'
failover node to switch to there. However, if your primary servers fail for
some reason, you could bring up another instance to take over that session.
There may be issues if you have a CEP environment with realtime
Things are clearer now!
I'll analyze the environment and try to apply one of the solutions. Probably
I'll be back with some more questions later.
Thank you!!

Hi guys, I appreciate your promptness!!
@salaboy, thank you for the clarification. I'll skip Grid then.. however
replication is not exactly what I need.
@laune, at the first boot the server will be empty. I don't need initial
(static) facts to be loaded, though it has to keep facts inserted over

One thing I couldn't figure out is how to trigger events (fusion) based on

facts, how to listen to N servers? To clarify, an example:

So if I want to know the whole world I have to scale up, right?
Ok, I'll try to work with this..
Anyway, is there any plan to implement shared sessions for further releases?
Thanks,

Hello all,
After searching the web and Drools forums for a couple of days, I couldn't
find a solution to the problem I've got to solve. Anyway, if there's a
thread pointing at the same problem, I apologize and please, let me know
where it is.
My current scenario involves a Drools cluster and
Hi Mauro,
At this moment you can't share the session state between multiple nodes.
You can replicate your sessions in different nodes. Which means that two or
more nodes will contain the same set of facts.
Drools Grid was an experiment, so I don't recommend you going on that
direction.

Processing a fact does take some time. But there's no guarantee that
distributing whatever results from this processing to another node and
incorporating it there into an application results in any considerable
saving as compared to distributing the original facts and repeat the
processing
