Effecient way to update a large set of objects with Hibernate?
What are the principles of efficient select'n'update of large sets of objects via Hibernate?
- Each object could be updated independently
- Required: efficient memory usage (no out of memory error)
- Required: efficient select
- Required: efficient flushing into DB
I believe stored procedures or the single update query could be much more effective than dealing with each object separately but I want no use them now. I'm using Grails 2.2 actually.
