Logs tell you what your code tried to do.
Audit tables tell you what your system actually did.
This article shows how to build a production-grade audit trail with Quarkus, Hibernate Panache, and Envers — including revision history and timestamps you can trust.
Hands-on. No fluff. Real systems only.

[Перевод] How to speed up mass data inserts in PostgreSQL when using Spring
A common task in enterprise systems is to load large volumes of data into PostgreSQL — sometimes tens or even hundreds of millions of rows. At first glance, this seems simple: just write a loop in Java and call save() for every record. But in reality, such an approach can be painfully slow. Even a perfectly tuned PostgreSQL instance won’t help if the application is sending data inefficiently. This article explains how to significantly accelerate bulk inserts when working with PostgreSQL through Spring and Hibernate. We’ll walk through which Spring and Hibernate settings are worth enabling, why they matter, and how much performance they can actually unlock. We’ll also look at how to build your own data-insertion layer for PostgreSQL — one that lets you switch between different insertion strategies, leverage PostgreSQL’s custom capabilities, and parallelize the process. Finally, we’ll see how to integrate this layer with Spring and what real gains each approach can deliver.

Очарованные Hibernate: проблемы, которые ведут разработчика странствовать по production
Hibernate часто работает как надо ровно до того момента, пока не приходит настоящая нагрузка. И тогда выясняется, что безобидные на вид решения отключают batching, ломают пагинацию, умножают число запросов и даже незаметно открывают дополнительные транзакции — ровно там, где вы рассчитывали на один аккуратный запрос в рамках одного unit of work. В этой статье мы постарались собрать добрую дюжину самых неочевидных и при этом действительно продакшн-критичных ошибок работы с Hibernate: как они проявляются в логах и метриках, почему возникают на уровне механики ORM, и какие предохранители помогут поймать их до релиза. Будет практично, предметно и с несколькими моментами, после которых захочется пересмотреть пару любимых паттернов в вашем проекте. поехали ...
