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 anywhere.
Persisting a session that has been loaded with some initial (static) facts and distributing that is another matter - but is this what you have in mind? -W On 04/04/2013, mauro <mdurant...@gmail.com> wrote: > 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.
