Re: [rules-users] Does rule execution block when the Knowlege Agent is rebuild KnowlegeBase???

We've tested this behavior under load and there is a brief (duration of about 1 - 1.5 seconds) uptick when the rulebase switch happens, but we noticed consistent and rapid recovery. I have not confirmed this but I believe what happens is a new KnowledgeBase is built, and once it's build is complete, it does a swap which causes the brief uptick. I don't believe there's any blocking going on while the KnowledgeBase is built however.

Hello Drools User, I am using Knowlege Agent to monitor changes in the repository. I have started the following services: ResourceFactory.getResourceChangeNotifierService().start(); ResourceFactory.getResourceChangeScannerService().start(); I was able to change the rules in the repository and the changes did get pick up in my application and everything is working fine as expected. However, I have a question regarding rule execution when the Knowlege Base is in the middle of being build by the Knowlege Agent. What happen when I execute the rules using: ksessionStateless = knowledgeAgent.newStatelessKnowledgeSession(); ksessionStateless.execute(ObjList); Will the method ksessionStateless.execute(ObjList) block and wait until the Knowlege Base is finish being build by the knowledge agent or the method won't block and just pick up the old Knowlege Base and then switch to the new knowlege base when the knowlege agent is finish building it? Will the method ksessionStateless.execute(ObjList) block or not block? thanks very much in advace for any help on this!
