Hi everybody,

in our project I see in many places that an entity (which allready exists in database) is persisted explicitly inside a transaction/hibernate session.

As far as I know, the session is flushed at the end of the transaction to the database anyway. So, what is the point of persisting it during a transaction?

Is it not more performant to wait until the end of transaction such that hibernate handles it alone?

Another question (actually related to this one):
Does hibernate open one database connection per transaction? How is explicit persisting inside a transaction handled in hibernate?

Thanks in advance...
