Add support for batch operations in StatelessSession
----------------------------------------------------
Key: HHH-1815
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815
Project: Hibernate3
Type: Improvement
Components: core
Environment: all
Reporter: Eric Williams
Priority: Minor
The principal use cases for StatelessSession seems to be in batch-oriented processing. However, there is no support for batch inserts or updates of persistent entities in the StatelessSession interface. This severely handicaps its usefulness for batch data loading.

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815?page=comments#action_23278 ] Eric Williams commented on HHH-1815: ------------------------------------ I'm not sure I understand the use of an update query. If you're referring to the use of INSERT INTO ... SELECT FROM, that's not what I'm trying to get at. My essential problem with StatelessSession is that I can't batch-insert objects that I have in memory. Currently, I can only insert(object), not insert(array of objects). The enhancement request was to provide capability to insert(array of objects), using appropriate JDBC batching. Is this somehow accomplishable with Query.executeUpdate()? > Add support for batch operations in StatelessSession > ---------------------------------------------------- > > Key: HHH-1815 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815 > Project: Hibernate3 > Type: Improvement > Components: core > Environment: all > Reporter: Eric Williams > Priority: Minor > > > The principal use cases for StatelessSession seems to be in batch-oriented processing.

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815?page=comments#action_23280 ] Steve Ebersole commented on HHH-1815: ------------------------------------- Yes, I have been giving this thought already. It is really needed for StatelessSession to be as useful as it could be in terms of performance. Unfortunately I am bogged down in JPA stuff right now. Please have a look and feel free to submit a patch in the meantime. > Add support for batch operations in StatelessSession > ---------------------------------------------------- > > Key: HHH-1815 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815 > Project: Hibernate3 > Type: Improvement > Components: core > Environment: all > Reporter: Eric Williams > Priority: Minor > > > The principal use cases for StatelessSession seems to be in batch-oriented processing.

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815?page=comments#action_23284 ] Emmanuel Bernard commented on HHH-1815: --------------------------------------- To be more specific, Hibernate seems to handle transparently batch operations already since it uses JDBC batch update underneath. Did you try it? It is defeated if you use a generator that requires an intermetdiate SQL operation inbetween (like sequence). But for batch operation, you should consider hilo or seqhilo anyway. > Add support for batch operations in StatelessSession > ---------------------------------------------------- > > Key: HHH-1815 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1815 > Project: Hibernate3 > Type: Improvement > Components: core > Environment: all > Reporter: Eric Williams > Assignee: Steve Ebersole > Priority: Minor > > > The principal use cases for StatelessSession seems to be in batch-oriented processing.
