High-Performance Java Persistence – Chapter 14 – Batching
Imagine having a tool that can automatically detect JPA and Hibernate performance issues. Wouldn’t that be just awesome?
Well, Hypersistence Optimizer is that tool! And it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, or Play Framework.
So, enjoy spending your time on the things you love rather than fixing performance issues in your production system on a Saturday night!
Part 2, Chapter 14
Every new chapter of my book is released right after it’s being completed, so the reader doesn’t have to wait for the whole part to be finished to get access to new material.

This chapter explains how batch updates work in Hibernate.
14. Batching 14.1 Batching insert statements 14.2 Batching update statements 14.3 Batching delete statements
Batch updates can have a great impact on data access layer performance, and Hibernate makes it very easy to switch from non-batchable statements to batched
PreparedStatement(s). In this chapter, I explain how you can enable JDBC batching for insert, update, and delete statements.
Because setting the
hibernate.jdbc.batch_size configuration property is not always enough, I also explain how statement ordering can leverage JDBC batching when using entity state cascading.
Aside from writing this chapter, I managed to review all the previous chapters for typos and grammar issues, thanks to using Grammarly.
Previously, I was relying on Office for correcting grammar issues, but, although it definitely helped me, I noticed that it was not enough. For this purpose, I purchased a Grammarly subscription and went through all the previous chapters for fixing typos and other grammar-related problems.
