[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5935) stateless session does not commit in batches by default, it commits one by one

radhakrishna commented on HHH-5935:
-----------------------------------

Can you atleast add a insertAll(entities) or saveOrUpdateAll(entities) that does it in batches, otherwise there is no use of statelessSession for improving performance and remove this section:

> inserts entity by entity which is completely ABSURD. Should'nt it insert all of them or none, rather it is inserting one by one by default. I have been using this to insert millions of records assuming it is batching, which is a shame.
