[Persistence, JBoss/CMP, Hibernate, Database] - Performance problem with LEFT JOIN

by toni

Hi, I have a LEFT JOIN, which looks like this: | | entityManager.createQuery("SELECT t FROM Template t LEFT JOIN t.messages c WHERE t.client.hostname=:ch GROUP BY t.id, t.subject, t.text, t.client ORDER BY count(c)").setParameter("ch", client.getHostname()).getResultList(); | The problem is that the larger the table grow the poorer the performance is. After a while it takes about 3-4 seconds to execute. Any ideas how I could optimize this?

[JBoss Seam] - Re: javax.ejb.EJBNoSuchObjectException

by stu2

You'd get the same behavior by just using a pojo. They're event-scoped by default for that reason. Using a SFSB that way certainly works, but if you look at the interceptor stack, there's definitly more overhead when using a SFSB as a pojo.

I think you'd get a better response if you posted more details of what you're doing. it's tough to follow your description.

[JBoss jBPM] - Re: Forked processing in jBPM

by kukeltje

Yes variables can be scoped, but I do not know to what extend and how exactely. I just never used it. Look at the tasknodeimpl to see how it is done there.
