title: Changing hibernate batch size programmatically
body: <p>Is possible to change hibernate.jdbc.batch_size programmatically? I understand
  hibernate.jdbc.batch_size is a application level parameter, wanted to know if I can use it 
  specifically for certain HQL inserts and not others. I would change the code only for those HQL inserts</p>
  
  <p>The big picture is that I need to introduce batch inserts to make the web application performant in some scenarios, but I do not want to jeopardize the normal inserts which work right now.</p>
