Hi Alex, It is here: https://github.com/droolsjbpm/droolsjbpm-contributed-experiments/tree/master/twittercbr We would like to develop a proper web GUI for it and integrate it with Guvnor that now supports CEP constructs, but did not had the time to do it yet... if anyone would like to help,

Re: [rules-users] Drools-Fusion : Inserting an Event in to an "entry-point" stream in the RHS of a rule?? Pls help

I need to check if that's the correct syntax, but in the right hand side as far as i know you can also do insert() and retract() that uses the kcontext to be executed. I think that is just syntax sugar from the parser side. 2011/8/4 Wolfgang Laun > > > 2011/8/4 Mauricio Salatino > >> there is

Re: [rules-users] Drools-Fusion : Inserting an Event in to an "entry-point" stream in the RHS of a rule?? Pls help

there is short way to do the same without using the kcontext: you should be able to do something like: entry-point['Temporal Reasoning'].insert(evt); Please check the syntax in the docs. 2011/8/4 Esteban Aliverti > This should work: > > when >... > then > TransactionEvent evt = new

Re: [rules-users] Drools-Fusion : Inserting an Event in to an "entry-point" stream in the RHS of a rule?? Pls help

This should work: when ... then TransactionEvent evt = new TransactionEvent(); evt.setMessage("Temporal Reasoning"); kcontext.getKnowledgeRuntime().getWorkingMemoryEntryPoint("Temporal Reasoning").insert(evt); end Best Regards, Esteban Ali

Re: [rules-users] Drools Fusion Performance Evaluation

The standard well-established answer to this kind of question is that no benchmark can provide a reliable basis for predicting the behaviour of any particular application. It's easy to benchmark the simple insertion of facts (= events) where there is no or just a single rule; this will give you an

[rules-users] Drools Fusion Performance Evaluation

Hi all! Can anybody point me to a performance evaluation of Drools? I found some papers [1], [2] which focus on the rules part but I'm particularly interested in the event processing part of Drools. I want to know how many events can be processed per second with which latency, something that is
