Does OpenJPA support sql batching (i.e. the jdbc addBatch api on a prepared Statement)? The user's guide shows how to set the addBatch limit, but it does not work. It would appear that if there was code to do this it was removed.
I think that most ORM runtimes support this feature and we will be at a competitive disadvantage with Hibernate and TopLink without it. It is very important when creating and persist many new object of the same type in one transaction (i.e. persisting 1000 new Customer beans) or doing many updates ( updating the salary on 1000 Employee beans). I know that addBatch performance vs. doing multiple jdbc executeUpdate makes a big differrent in DB2 -- and I would assume also other databases. If the code was there and removed -- any thoughts about adding it back in? Otherwise we would most likely have to develop it for our enterprise customer.
