This was my point. Sounds like you agree. :) The current CMP design has problems with large, complex reads. You can't effectivly use CMP for everything, nor was the EJB spec's CMP section able solve ALL data query problems.

A lot of applications increase performance by offloading processing to the database with very complex queries and stored procedures, and the current CMP design can not benefit from this design. The JBoss 4.0 design will be able to benefit from hand tuned queries. > I'd venture to guess the same performance problem will occur on other app > servers, in which case, it is not a war of servers, but a principle of > application design (SSB+JDBC vs. CMP).

My goal for the 4.0 architecture is to enable the easy use of a hybrid approach to CMP. In this design you can use CMP for the 98% of you app that performs well under the current code and for the 2% that needs hand code you can plug in a custom interceptor to tune queries. -dain ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
