Martin Ross commented on HHH-1:
-------------------------------
Please remember that JDBC batch size is a huge factor in determining the performance speed
up you with get. The larger the batch size the more efficient the grouping algorithm plus
the fewer insert statements are required. We have typically used a few hundred at least.
Optimize Hibernate for the bulk insertion of related entities
-------------------------------------------------------------
Key: HHH-1
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-1
Project: Hibernate3
Type: New Feature
Components: core
Environment: Hibernate 1.2, MySql 3.1
Reporter: Bradley Leupen
Priority: Minor
Attachments: bulk_insert.patch
It is currently difficult to batch the creation of persistent entities that maintain
associations with other entities.
Add necessary api to hibernate to support the save or update of a collection of entities.
An optimization can be applied in this scenario to group inserts / updates by entity
class, or table. This will enable the hibernate engine to utilize batching if available,
drastically improving performance over a network.
