Allow batching inserts for multi-table entities ----------------------------------------------- Key: HHH-2558 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2558 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Steve Ebersole <joined-subclass/> as well as entity's containing <join/> mappings currently cannot participating in JDBC batching. The reaons being that the actions (i.e. Executables) perform the insert or update in an atomic fashion through the persisters; the persisters perform the multiple statements. One possible approach for solving would be to have the persisters somehow expose the fact that inserts or updates effect multiple tables and to have the actions drive the executions of those statements. Another possible approach would be to change how Batcher works. Currently, batcher is capable of tracking a single jdbc batch statement, which it does by string comparison of the sql. So a new sql command is seen as the impetus to start a new batch. So we could change this to make batch a logical concept such that the "grouping" is actually at a higher level : like say "[command]:[entity-name](:[id])". Then we could have batches keyed by "update:Customer:1" rather than "update CUSTOMER set ...". Would need to be very careful in the case of dynamic-insert and dynamic-update...
