[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5498) Extend AuditReader interface to support batch queries

Extend AuditReader interface to support batch queries ----------------------------------------------------- Key: HHH-5498 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5498 Project: Hibernate Core Issue Type: Improvement Components: envers Reporter: Erik-Berndt Scheper Currently the Envers AuditReader interface only supports retrieving single instances of: * Revision-entities, using: ** {{findRevision(Class<T> revisionEntityClass, Number revision)}} * Audited entities, using: ** {{T find(Class<T> cls, Object primaryKey, Number revision)}} For a moderately sized object graph, this leads to an extremely large amount of queries sent to the database if one needs to retrieve the history of a graph. This severely degrades the performance. Batching these queries improves performance significantly (in our case: easily 5 to 20-fold). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
