What if I've got CMP and BMP beans mixed... -----Original Message----- From: danch [mailto:[EMAIL PROTECTED]] Sent: Monday, June 25, 2001 12:17 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-dev] finder optimization(read-ahead) phase 3 Bill Burke wrote: > >> > > > Can you explain this again in other words?

We can also do a look aside for option A (as you said higher up in your email) to make sure we don't read-ahead something that's already in the cache. Here goes again for my rational: In option A, we own the database, so there can be no external changes. If the data is changed by another transaction in JBoss, it will go through JAWS load code first, so the data will be taken out of the read-ahead before it is modified. Have I missed something? thanks, danch _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-development _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-development
