http://opensource.atlassian.com/projects/hibernate/browse/HHH-5372?page=c...
]
Matthew B. Jones updated HHH-5372:
----------------------------------
Attachment: revend_queries.txt
Provided patch (co-written by Chris Bates) which optionally changes the queries Envers
uses if the strategy is enabled, to use the REVEND columns for dramatic performance
improvements.
Improve envers query performance by using new REVEND column
-----------------------------------------------------------
Key: HHH-5372
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5372
Project: Hibernate Core
Issue Type: Improvement
Components: envers
Affects Versions: 3.6
Reporter: Matthew B. Jones
Attachments: revend_queries.txt
When the ValidTimeAuditStrategy is enabled: <property
name="org.hibernate.envers.audit_strategy">org.hibernate.envers.strategy.ValidTimeAuditStrategy</property>,
it would be desirable to have the Envers API leverage the useful REVEND columns to avoid
slow subselects.
