The problem is that even if you are flushing your first level cache, you may not be batching your SQL statements.

Hibernate flushes by default for the following reasons: The thing to note here is that until the session is flushed, every persistent object is placed into the first level cache (your JVM's memory).

So if you are iterating over a million objects you will have at least a million objects in memory.

To avoid this problem you need to call the public void do Batch() [/sourcecode] Assuming the Customer cascades save to the Cart object you would expect to see something like this in your SQL logs: [sourcecode language='sql'] insert into Customer values (...) insert into Cart values(...)
