Hello,

I am mapping a POJO to a table with an extreme amount of columns (1000). Thus, this bean has 1000 accessor methods (get/set). I can avoid sending large update statements by loading the object from cache and apply changes within the same transaction. I have noticed that Hibernate only updates the changed properties on the bean, which results in highly efficient update statements.

With the network and driver performance issues out of the way, are there any other impacts of mapping such large beans?

Thanks for your feedback.
