Dear all, We posted this question two weeks ago, but with no replies. please forgive me for posting it again.
In our business, most of the facts have time-stamp attributes. For example, each laboratory test (a fact) has the time stamp when the sample was taken, and when the machine produced the result value. In our business-logic, we often analyze the relation between facts using these attributes. For example: 1) finding two adjacent labResults with an increasing value 2) checking whether 3 facts are consecutive 3) counting the number of facts fulfilling a specific constraint within a specific time window. We were happy to read (in the blog) about the new CEP feature which is about to be added to drools 5.0. * Where can we find a more detailed description of CEP functionality in drools? * Is it a good idea to use CEP for analyzing historic data (retrieved from the database)? or is it best for online data. * Can we use CEP in a stateless session? * As we understand, CEP attaches to each fact a temporal attribute of the assertion time. Can we define that a particular attribute (e.g., LabResult.samplingDate) will be used as the time stamp? Or, should we assert the facts by their temporal order, and advance the session-clock appropriately? * Can we use CEP to analyze the data in the examples above? Many thanks for the help, David -- View this message in context: http://www.nabble.com/CEP-functionality-tp19020709p19020709.html Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
