[jboss-jira] [JBoss JIRA] (DROOLS-5113) Do not compile exec model classes in RAM

[Luca Molteni (Jira)]

     [ https://issues.redhat.com/browse/DROOLS-5113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Luca Molteni updated DROOLS-5113:
---------------------------------
    Description: 
Currently executable model classes are compiled in RAM

	at org.drools.compiler.commons.jci.compilers.AbstractJavaCompiler.compile(AbstractJavaCompiler.java:49)
	at org.drools.modelcompiler.builder.CanonicalModelKieProject.writeProjectOutput(CanonicalModelKieProject.java:81)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildKieProject(KieBuilderImpl.java:285)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildAll(KieBuilderImpl.java:247)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildAll(KieBuilderImpl.java:204)

This kie-benchmark fails when running with 10000 rules with the exec model and the lambda externalization activated 

mvn clean install -DskipTests=true && java -jar ./target/drools-benchmarks.jar -jvmArgs "-Xms10000m -Xmx10000m -Ddrools.externaliseCanonicalModelLambda=true -XX:+UseG1GC -XX:MetaspaceSize=1000m -XX:MaxMetaspaceSize=1000m -XX:+PrintGCDetails -Xloggc:/tmp/g1-dedup-metaspace4-maxpause.log" -foe true -rf csv -rff results.csv org.drools.benchmarks.turtle.buildtime.BuildKieBaseFromContainerBenchmark

Probably we could start bringing the benchmark code into Drools so that we can debug it with idea (in JMH you can't) with the OpenJDK source code attached
