The team released #Hibernate ORM 7, Hibernate Data Repositories & Hibernate Validator 9.

#Jakarta EE 11:
- Persistence 3.2
- Data 1.0.
- Validation 3.1

This is the first version available entirely under the Apache Software License. (Including #Envers!)

In Relation ToHibernate 7 (and Hibernate Validator 9) - In Relation To Today—​or rather, late last night—​we released Hibernate ORM 7, which includes the latest version of Hibernate Data Repositories. We’ve also released Hibernate Validator 9. Hibernate ORM 7 features a complete implementation of Jakarta Persistence 3.2 and of Jakarta Data 1.0. Hibernate Validator 9 implements Jakarta Validation 3.1. This is the first production-ready version of our platform available entirely under the Apache Software License. (Yes, that includes Envers!) And it’s the first version of our platform to fully support Jakarta EE 11. Compared to the massive reengineering effort that went into Hibernate 6, this release is much more incremental, and most users should experience a smoother migration. But, as befits a major release, we’ve removed some deprecated functionality. So let’s get the bad news out of the way first.

Hibernate 7 beta 4 is now available

#Java #Hibernate #JakartaEE

In Relation ToHibernate 7 beta 4 is now available - In Relation To The fourth beta release of Hibernate 7 is now available. Along with many bugfixes and minor improvements, this release features the following enhancements: The brand-new Restriction, Path, and Range APIs make it easy to add programmatic restrictions to HQL queries or Jakarta Data repository methods in a completely type-safe way. The package org.hibernate.graph was completely re-engineered, fixing a number of long-standing issues with our implementation of the Jakarta Persistence EntityGraph API. StatelessSession is now able to make use of the second-level cache, reflecting the changing role of this very important API in the Hibernate ecosystem. Reactive repositories backed by Hibernate Reactive are now a documented feature of Hibernate Data Repositories. The hibernate-jfr module was enhanced to send more events to Java Flight Recorder. HQL now provides portable sha(), md5(), and hex() functions. Hibernate Processor now features much better support for inner classes.

Do you remember me talking about this wonderful article? the one where you are taught in detail with source snippets how Linux goes bye-bye when it goes to sleep?
The article has so much in-depth details that it takes a lot of time, considerable inteligencia & knowledge to process. Contrary to others I will not only say it, I will explicitly state it is fascinating and a heavy read.

Take your time to process the article; it's worth learning this in depth, in miniatures detail, all the way down to the sources, so you know what goes on, when the power management or your Linux powered VM, or Linux powered Hardware machine, goes down, hard, inexplicable:

To you it will become explainable!

The code snippet is from the file "kernel/power/main.c:688". It defines a static function named "decode_state" that takes a "con" argument. Inside the function, there are preprocessor directives using "#ifdef CONFIG_SUSPEND". It declares variables "state" of type "suspend_state_t", a character pointer "p", and an integer "len". The code uses "memchr" to find a newline character in a buffer and calculates the length. There's a comment "/* Check hibernation first. */" and an if statement that checks the length and a string prefix, potentially returning "PM_SUSPEND_MAX". Another "#ifdef CONFIG_SUSPEND" section includes a for loop that iterates through suspend states, comparing labels and lengths, and potentially returning the "state". Finally, the function returns "PM_SUSPEND_ON". Below the code, there's a comment stating: "Could we have figured this out just via function names? Sure, but this way we".

@thjanssen123 This post is full of pure gold if you're using #Hibernate. When optimizing your queries for a #OracleDB keep in mind Oracle supports function-based indexes. Use the DBMS_STATS package to regularly create histograms for the indexes/the indexed table columns.
When designing your data model remember Oracle does not index the null value. Also do not distort index histograms with default values (as a fix to the null problem). If handling larger datasets index range scans are key.

Writing an efficient persistence layer with #Hibernate (or #SpringDataJPA is simple and complicated at the same time.

It's simple because avoiding common pitfalls and following best practices is good enough for most applications.

And it's complicated because there are many of them. To make it even worse, some are tied to specific Hibernate versions and circumstances.

In this article, I summarize my most important tips to avoid and fix performance problems:
