Slow build due to inefficient EnumServiceImpl.doValidation() call ----------------------------------------------------------------- Key: DROOLS-4285 URL: https://issues.jboss.org/browse/DROOLS-4285 Project: Drools Issue Type: Bug Components: Enumerations Editor Affects Versions: 7.23.0.Final Reporter: Michael Anstis Assignee: Michael Anstis Priority: Critical Labels: drools-tools, support In a live environment with ~1300 assets, the project build takes ~20 minutes when invoked in decision-central. Using a debugger, I observe that one execution of KieModuleMetaInfo.unmarshallMetaInfos() takes 20 seconds. It's called from EnumServiceImpl.validate(). {noformat} at org.drools.core.rule.KieModuleMetaInfo.unmarshallMetaInfos(KieModuleMetaInfo.java:49) at org.kie.scanner.KieModuleMetaDataImpl.indexMetaInfo(KieModuleMetaDataImpl.java:251) at org.kie.scanner.KieModuleMetaDataImpl.indexKieModule(KieModuleMetaDataImpl.java:100) at org.kie.scanner.KieModuleMetaDataImpl.<init>(KieModuleMetaDataImpl.java:85) at org.kie.scanner.KieModuleMetaData$Factory.newKieModuleMetaData(KieModuleMetaData.java:60) at org.kie.scanner.KieModuleMetaData$Factory.newKieModuleMetaData(KieModuleMetaData.java:48) at org.drools.workbench.screens.enums.backend.server.EnumServiceImpl.doValidation(EnumServiceImpl.java:272) at org.drools.workbench.screens.enums.backend.server.EnumServiceImpl.validate(EnumServiceImpl.java:263) at org.drools.workbench.screens.enums.backend.server.EnumServiceImpl.validate(EnumServiceImpl.java:253) at org.drools.workbench.screens.enums.backend.server.EnumServiceImpl$Proxy$_$$_WeldClientProxy.validate(Unknown Source) at org.kie.workbench.common.services.backend.builder.core.Builder.build(Builder.java:238) {noformat} However, {{EnumServiceImpl.validate()}} is repeatedly called in a loop in Builder.build(). So all ".enumeration" files call this method (this project has 18 .enumeration files). It results in 6 min in my env. Probably the unmarshalled KieModuleMetaInfo can be cached?
