When we profiled our application’s data import pipeline, we expected the bottleneck to be in our business logic — JQ filters, JavaScript evaluation, recursive SQL queries. Instead, Hibernate’s internal JSON handling consumed over 50% of CPU time and allocated 20 GB of unnecessary objects during a routine import of 5 records.
Two small annotation changes fixed it. No code changes, no architectural redesign — just telling Hibernate what it needs to know about how our application uses its data.

A billion-dollar mistake
I recently appeared on the Tech Lead Journal podcast, and the host, Henry Suryawirawan, picked up on a comment I made about the cost of a mistake I made many years ago, namely, the mistake of underestimating the importance of Hibernate’s StatelessSession, and of not including it in the Java Persistence API.
You might think my statement a bit hyperbolic, and I guess it was intended in that vein, but let me give you a quick order-of-magnitude computation suggesting that my estimate was not far off.
The cost of this mistake should rightly include:
