[jboss-jira] [JBoss JIRA] (DROOLS-1624) Map Handling with Property Reactive Always Enabled

KimJohn Quinn created DROOLS-1624: ------------------------------------- Summary: Map Handling with Property Reactive Always Enabled Key: DROOLS-1624 URL: https://issues.jboss.org/browse/DROOLS-1624 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.0.0.Final Environment: * JDK8 * Docker running Alpine Reporter: KimJohn Quinn Assignee: Mario Fusco Priority: Minor Referencing a conversation on [Google Groups - Drools Usage|https://groups.google.com/forum/?fromgroups#!topic/drools-usage/G7r...] and as requested by Mario Fusco... We currently have a ruleset that relies heavily on Map facts. In Drools 6.5 we fire approximately 400 rules. In Drools 7.0 we get only about 50 rules unless we add the "<property key="drools.propertySpecific" value="ALLOWED"/>" to the kmodule.xml, in which case we fire the full 400 rules or by using @Watch(*) or @Watch(!*) on the rules. It "seems" like only the first evaluations of the rules are firing and then no others after that. Our flow generally follows something like below, within a stateful session, using rules only. We fire all rules per-request then close the session. Watch for changes to the Map properties If a certain property or properties exist a 'populate' rule fires (calls modify()) The populate rule enriches the map fact. (calls modify()) Based on #3, more rules fire when certain properties exist (calls modify()) We are work heavily with rules that depend on loaded available facts up-front and computed properties throughout evaluation. I have a couple of usage questions regarding Drools 7, the default enabling of Property Reactive and using Maps as the facts: In general, how do maps work with property reactive and respond to modify/insert events? Does Drools look at the Map as a whole, any change re-evaluates the tree, or each individual property within the map re-evaluates the change? In Drools 7, by defaulting the property reactive setting, does that mean all rules need to be annotated or they should they work as is (dao or map-based facts) when using modify/insert? For reference, we are relying on this doco https://docs.jboss.org/drools/release/7.0.0.Final/drools-docs/html_single.... I am looking into details or an example how to properly use Maps in Drools 7 with Property Reactive features always enabled (as suggested per the doco).... -- This message was sent by Atlassian JIRA (v7.2.3#72005)
