Answer 1

To enable batch insert you need the batch_size property which you have in your configuration.

Also since a jdbc batch can target one table only you need the spring.jpa.hibernate.order_inserts=true property to order the insert between parent and child or else the statement are unordered and you will see a partial batch (new batch anytime an insert in a different table is called)
