Daniel Grove commented on HHH-2224:
-----------------------------------
This is a major problem for our system right now because we use transactional JBoss Cache
with optimistic locking. None of our second-level cache objects are related to the bulk
updates, but regardless all entity cache is cleared. This often causes failures because
another transaction has made changes to an entity in the cache. Are there any hopes for a
patch? Does anyone know of a workaround?
Thanks,
Daniel

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.
