Enable specifying the fetch mode for map-key-many-to-many and index-many-to-many
--------------------------------------------------------------------------------
Key: HHH-5924
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5924
Project: Hibernate Core
Issue Type: New Feature
Components: core
Affects Versions: 3.6.1
Environment: doesn't matter
Reporter: Robert Wruck
The documentation says that with many-to-many "... for full eager fetching in a
single SELECT of an entity and its many-to-many relationships to other entities, you
would enable join fetching,not only of the collection itself, but also with this attribute
on the <many-to-many> nested element".
This seems to also apply to map-key-many-to-many and index-many-to-many where the default
setup generates 1+N SELECTs. Unfortunately the DTD (and maybe hibernate itself) currently
doesn't support specifying fetch="join" for these elements.
