问题
Each time I save() a new domain object in Grails I see Hibernate issuing Select statements for each of the unique constraints in my Grails domain class.
If I save without validation, I don't see the Select statements. Example:
new Person(name: 'Foo').save(validate: false)
Is there a way to stop these extra Select statements from occurring while still having validation enabled?
One of my goals is to decrease appserver/database chattiness since I am expecting my Grails app to run on a high latency network (e.g., communicating from Grails app => DB can be costly).
Burt has one suggestion, but I'm hoping for something easier/cleaner:
- Grails save() Domain Object actually does a Select?
This may be a Hibernate issue more than Grails. I'm not sure.
Maybe some other related info:
- Why does hibernate do the SELECT before SAVE?
- select Query Run for hibernateTemplate.save()
- Force Hibernate Insert Without Select Statements
