2014 – A year in review

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!



In the beginning of 2014, I took the initial version of my time series MongoDB aggregation example and pass it through a multistage optimization process, from indexing to advanced data-modelling:


In February, I starting developing FlexyPool, the ultimate connection pool sizing utility. This was a great opportunity to dig into Queuing Theory and the following articles capture some of my findings:


After finishing FlexyPool, I decided investing in a Data knowledge stack, and so I started working on my Hibernate Master Class training material.

The Hibernate Master Class allowed me to dig into a great variety of JPA/Hibernate features, some of which are lesser known:

Almost at the time, I started answering Hibernate StackOverfow questions, and I accumulated a reputation on 8918 points.


In August, I was elected One of August’s Most Interesting Developers by Jelastic.

If you wonder what happened with my open-source Java Transactions Book, you can take a look on the Concurrency Control section of the Hibernate Master Class:

I decided to include my knowledge about transactions in the Master Class material since you can’t separate transactions out of the run-time environment anyway.


In September my blog’s just turned one.


Although I didn’t win the Most interesting developer competition, I’m proud I managed to finish on the 3rd place.

I want to read more books than I did in 2014.
