[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3808) Manual fetching of associations

Manual fetching of associations ------------------------------- Key: HHH-3808 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3808 Project: Hibernate Core Issue Type: New Feature Components: core Reporter: Ovidio Mallo In performance critical parts of an application, batch fetching and subselect fetching not always allow for an efficient and specific prefetching of entity associations. Therefore, I wanted to propose to add some API which allows to prefetch a given association for a user defined set of entities. This could be something like Session#fetch(Class ownerClass, Serializable[] ownerIds, String propertyName) or Session#fetch(Class ownerClass, Object[] owners, String propertyName) or something similar. The method would then load the association for the given entities (just like batch fetching would do) and put the associations in the session cache for later usage. I think this would greatly help when performance really matters and you want to have full control about the set of entities on which an association is fetched. -- 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
