Re: [rules-users] More on thread safety of working memory

This horse has been beaten pretty hard (http://thread.gmane.org/gmane.comp.java.drools.user/3557/focus=3585), but I have a newish angle on it. My app has a big collection of business objects (1000 of type X, 10,000 of type Y, 200 of type Z, etc) asserted into a single working memory. These objects need to be updated from external sources periodically. Because each object type has a different source, I'd like to parallelize the updates in separate threads. Some of the updates involve retraction of expired objects or assertion of new ones, but most are just changing fields on already-asserted objects (all fields have PropertyChangeListener (PCL) support). I think that using a SynchronisedWorkingMemory will handle the assert/retract updates. Will it be "happy" in the face of PCL changes as well, or do I need to do something more? -- Dirk Bergstrom dirk(a)juniper.net _____________________________________________ Juniper Networks Inc., Computer Geek Tel: 408.745.3182 Fax: 408.745.8905 _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
