hi,

on serverside.com there's a pattern called 'Fat-Key' that may help to solve
this problem:

Thanks Danch!

(even if the answer does not make me happy ;) )

 -Message d'origine-
 Finders currently hit the database n+1 times (where N is the number of
 beans selected by the query).

  When using CMP and invoking a ejbFindXXX method returning a

[JBoss-user] CMP and finders: optimized?

2001-05-04 Thread Sacha Labourey 

Hello,

I have question regarding the way finders work in the current
implementation.

When using CMP and invoking a ejbFindXXX method returning a collection of
beans, if I then invoke a method on each of these beans, will they each
require a DB call (select * from xxx where PK = x) or does the ejbFindXXX
call cache the DB information that can be reused for these subsequents bean
calls (during the whole transaction)?

Thank you. Cheers,



Sacha
