Hello!
We are thinking about using Drools Fusion 5.1 for Complex Event
Processing. We have a prototype running that consumes events from a
Tibco JMS server. Everything works as expected. My boss is now asking
about HA features that are available. I have read the documentation
and found nearly nothing about HA features. In the case of Fusion you
have long running threads working on fireUntilHalt(). So when the node
goes down you loose all the events that live in the ksession memory.
What possibilities do you see to run Fusion in an HA environment?
There are two bespoke solutions you can do.
1) Setup 2 or more engines and the JMS queues sends facts to both so
that you have redundancy.
2) Keep all facts in a HA cloud, using something like infinispan, if the
engine goes down restart it and reload the data.

Thanks for your ideas
