[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2224) executeUpdate causes coarse cache invalidation

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37621#action_37621 ] 

Steve Ebersole commented on HHH-2224:
-------------------------------------

Patrick is spot on.  There really is no other option here.  I am not going to add an option that allows developers to tell Hibernate to leave itself in an inconsistent state.

Now, could we perhaps allow a means to plug in a different behavior in "bulk operation cleanup".  The concern is applications/developers leveraging that and then the Hibernate team having to deal with bug reports when erroneous stuff starts getting returned because it was not properly invalidated from the second level cache regions during some custom "bulk operation cleanup".

> I am developing an application and want to mix bulk-updates

> 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've attached a testcase for this.
