Hi there, We have upgraded some of our apps to Spring Boot 3, which also brings Hibernate 6. Since the upgrade we have noticed that the hibernate.jdbc.fetch_size property is not being respected. After some debugging I can see that the jdbcFetchSize field in SessionFactoryOptionsBuilder is being set…

jdbcFetchSize seems to be ignored
