Hello,
I have several SessionBean methods which retrieve lists os records from the
DB. If I wan't these methods to have no transaction, how can I avoid the
"performance penalty" referred on the book JBossCMP (Chapter 6->Optimized
Loading->Transactions)?
Book Excerpts:
"The performance impact of running without a transaction will be demonstrated
with an example
similar to Listing 6-1. This example uses an on-find optimized query that
selects the first four
gangsters (to keep the result set small), and it is executed without a wrapper
transaction. "
"Normally this would be the only query executed, but since this code is not
running in a
transaction, all of the preloaded data is thrown away as soon as findAll
returns. Then at Arrow 2
JBossCMP executes the following four queries (one for each loop): 21..."
How can I avoid this penalty on methods without Transactions?
Thanks in advance,
Victor Batista
