In Relation To

One thing you don’t hear enough about in the microservices world is data. There is plenty of info on how your application should be stateless, cloud native, yadayadayada. But at the end of the day, you need to deal with state and store it somewhere.

I can’t blame this blind spot. Data is hard. Data is even harder in a unstable universe where your containers will be killed randomly and eventually. These problems are being tacked though in many fronts and we do our share.

But once you have dealt with the elasticity problem, you need to address a second problem: data evolution. This is even more pernicious in a microservices universe where:

I’m glad to announce the second release of the Eclipse plugin for Hibernate Search. In this post I’m describing the changes and new features of the release. Here you can find the first release blog post.

Today we’ll be talking about Hibernate Validator and how you can provide your own constraints and/or validators in a fully self-contained manner. Meaning packaging it all into its own JAR file, in a way that others can use your library by simply adding it to the classpath.

This functionality is based on Hibernate Validator usage of Java’s ServiceLoader mechanism that allows to register additional constraint definitions. But more on the details later.

What can be a real life scenario for building your own library with constraints and sharing it? Well, let’s say that you are building some library with data classes that user might want to validate. As it may be tough to keep track of all such libraries and write/maintain all those constraints for them - Hibernate Validator provides authors of such libraries a possibility to write and share their own validation extensions. Which can be picked up by Hibernate Validator and used to validate your data classes.

I’m happy to announce the latest stable release of Hibernate OGM: Hibernate OGM 5.1 Final

Compared to the latest candidate release, there are not many changes. You can have a look at the 5.1.0.Final changelog to get all the details.

In this post, I’d like you to meet Kevin Peters, a Software Developer from Germany and Hibernate aficionado.

In this post, I’d like you to meet Marco Pivetta, who is one of the maintainer of Doctrine, a suite of PHP projects that were inspired by Hibernate ORM.

I’d like to thank the Atlanta JUG for hosting DevNexus 2017 and the attendees to both my and Edson Yanaga’s presentations that covered ORM, Envers, OGM, and Search this year.

If you’re interested in the ORM slide deck from the conference, I have published it here.

You asked for it, we deliver: Hibernate Search 5.7.0.Final, with support for Hibernate ORM 5.2.8, is out! And of course, like previous versions, it features experimental support for Elasticsearch integration (even with some improvements).

Stuck on an older ORM version? Don’t worry, we also released a bugfix version for 5.6, namely 5.6.1.Final.

This time Emmanuel and Andrew sits down with Gunnar to talk about Beans Validation 2.0.

Episode 43 - Show notes and podcast.

Enjoy!

Starting with Hibernate ORM 5.2.8, MariaDB gets its own Hibernate dialects.
