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!

@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:

Oregon Health & Science University researchers have identified a process that could one day help clinicians lower body temperature in people experiencing life-threatening events, such as heart attacks or #strokes. If applied in humans, who can’t naturally #hibernate, the discovery could mimic the natural ability of certain animals to lower their body temperature during hibernation.
