Hello,
I want to ask you if it is a good practive to pool stateful sessions for a
specific ruleset to improve the execution performance.
Actually in my application I execute my rules by calling SOAP webservice.
For performance purpose, I test multithreaded calls to my webservice and I
noted that when I pool sessions in the server side, it improves the
performance a lot.
To pool sessions, I just declare multiple ksession tag in my kmodule.xml :
<kbase name="KBase" packages="com.example.*">
<ksession name="KSession1"/>
<ksession name="KSession2"/>
<ksession name="KSession3"/>
<ksession name="KSession4"/>
<ksession name="KSession5"/>
</kbase>
In my spring webservice endpoint I just put that code to handle the pool :
@Endpoint
public class ExampleEndpoint implements InitializingBean {
@Autowired
private ExampleRuleService ruleService;
private Map<Integer, Boolean> isRunningMap = new HashMap<Integer,
Boolean>();
private static final int NB_POOL_SESSIONS = 5;
@PayloadRoot(localPart = "com.example.ExampleRequest")
@ResponsePayload
public ExampleResponse handleRequest(
@RequestPayload ExampleRequest request) throws
InterruptedException {
KieServices ks = KieServices.Factory.get();
KieContainer kc = ks.getKieClasspathContainer();
while (true) {
for (int i = 0; i < NB_POOL_SESSIONS; i++) {
boolean run = false;
synchronized (isRunningMap) {
if (!isRunningMap.get(i)) {
isRunningMap.put(i, true);
run = true;
}
}
if (run) {
KieSession ksession = kc.newKieSession("KSession" + (i
+ 1));
ExampleResponse response = ruleService.run(ksession,
request);
ksession.dispose();
isRunningMap.put(i, false);
return response;
}
}
Thread.sleep(100);
}
}
public void afterPropertiesSet() throws Exception {
for (int i = 1; i <= NB_POOL_SESSIONS; i++) {
isRunningMap.put((i - 1), false);
}
}
}
It works well because in my benchmark I improve 5 times the performance (as
I have 5 different threads) but I wondered if it is a good practice and if
it does not hide any issues that I could have in the future.
Thanks for your help.

Hi maxime,
I do not remember if use drools 6 or drools 5. If you using drools 6.
Phreaks algorithm use multi threading according to use 'from
accummulate' far i understand here:
http://planet.jboss.org/post/drools_6_performance_with_the_phreak_algorithm
Instead to put a thread by ksession here rules evaluation are
multi-threaded.
5:27 a.m.
I'm sorry but I don't understand what you are talking about. In this
article, there is nothing about multithreaded rules evaluation. It just
says that the Phreak algorithm is designed for thread safety and
*future*multicore processors exploitation. It doesn't mean that it is
already
multithreaded. Moreover I tested my appliciation with and without
multithreaded sessions (I am using Drools 6.0.1.Final) and I noted a faster
execution in the multithreaded one.

Ah yes. Maybe Mark Proktor could tell some information about this
3:42 p.m.
as it says in the docs. we’ve designed things to put in foundations for future
multi-threaded exploitation, but there is nothing there now.
The example code doesn’t make too much sense to me. As you are saying you are using them
as a pool, but you are disposing after use.

I'm disposing after use because if i'm not the working memory is not empty
between 2 calls right ? And I am saying that I'm using them as a pool
because I have 5 sessions that could be used at the same time, which is
impossible if I declare only one.
If you have recommandation for my use case, please tell me as I found
nothing in the doc about this.
