Massive insert with JPA + Hibernate

Question

I need to do a massive insert using EJB 3, Hibernate, Spring Data and Oracle. Originally, I am using Spring Data and code is below:

talaoAITDAO.save(taloes);         


        

Answer 1

I recently found a promising small library for batching inserts with Hibernate and Postgresql. It is called pedal-dialect and uses the Postgresql - command COPY which is claimed by many people to be much faster than batched inserts (references: Postgresql manual, Postgresql Insert Strategies - Performance Test, How does copy work and why is it so much faster than insert?). pedal-dialect allows to use COPY without fully losing the ease of use of Hibernate. You still get automatic mapping of entities and rows and don't have to implement it on your own.
