Steve Ebersole commented on HHH-2224:
-------------------------------------
Vladimir, there is a significant difference between Hibernate allowing a certain
(incorrect) behavior and developers achieving this behavior by "[finding a] path
which by-pass this barrier". Namely in the first case the implication is that
Hibernate supports such a (incorrect) behavior, condones it even. How do you correlate a
read-only cache and things that can be updated?
Ioannis, as I said I am not ruling out a pluggable strategy where developers could
themselves choose this behavior. There is, again, a significant difference between
Hibernate providing the option to enable this behavior via switch etc versus it providing
the ability for developers to plug in this behavior. And trust me, if we go this route,
we will see bug reports here about how Hibernate served up incorrect cached results
because the user developed a bad pluggable "bulk operation cleanup" strategy. I
assume I can send them to you for a lecture on how they "are fully responsible"?
;)
executeUpdate causes coarse cache invalidation

Key: HHH-2224
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2224
Project: Hibernate Core
Issue Type: Improvement
Affects Versions: 3.2.0.ga
Environment: Hibernate 3.2.0.ga, Oracle 9.2
Reporter: Stefan Fleiter
Attachments: bulk_testcase.zip, hibernate-3.2.6_p4.patch
I am developing an application and want to mix bulk-updates
with normal hibernate operations.
The bulk updates work fine, but invalidate the whole region and I've found
no possibility to prevent this.
There would be 3 options to improve:
- Invalidate only the modified objects if the ids where given as Query-parameters.
- Let me deactivate the invalidation so I can invalidate the affected objects myself.
- Transform the DML to a select to gather the objects to invalidate before executing the
DML
The reference documentation does not mention caching at all:
http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#batch-direct
The best documentation I've found is:
http://blog.hibernate.org/cgi-bin/blosxom.cgi/2005/07/19#dml-basic
Maybe this could be added to the reference documentation...
I already posted this at the forum
http://forum.hibernate.org/viewtopic.php?t=966775
but did not get a single answer.
I've attached a testcase for this.
