Vladimir Kralik updated HHH-2224:
---------------------------------
Attachment: hibernate-3.2.6_p4.patch
Patch for hibernate 3.2.6, which adds configuration options
hibernate.cache.execute_update_clear_cache = true|false
default is true
true means criteria.executeUpdate() clears all caches defined in *.hbm.xml
false means criteria.executeUpdate() doesn't clear caches defined in *.hbm.xml
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.
