## What it is
A collection of 300+ runnable sample applications demonstrating Java persistence performance best practices using Hibernate 5/6 and Spring Boot 2. Each sample is a small self-contained project illustrating a specific tip, such as UTC timezone handling, DTO projections, batch inserts, and connection pooling.

## Use cases
- learn hibernate performance best practices
- optimize jpa query performance in spring boot
- fix n+1 select problem examples
- speed up batch inserts with spring data jpa
- reduce sql statement count in hibernate
- configure connection pooling in spring boot
- learn dto projections in spring data

## When to choose
- you develop Java persistence layers with Hibernate/JPA and Spring Boot and want practical, runnable examples
- you are tuning database performance and want copy-pasteable recipes
- you want to learn Spring Data JPA optimization patterns incrementally

## When to avoid
- you need a production library or framework to add as a dependency - these are sample applications
- you use Spring Boot 4 / Hibernate 7 (a separate companion repo covers that)
- you need non-Java persistence guidance

## Facets
- artifact type: learning-resource
- maturity: active
- function: orm, database, benchmarking, developer-tools
- domain: databases, developer-tools, tutorials, performance
- platform: jvm
- tags: hibernate, spring-boot, jpa, spring-data, persistence-performance, best-practices, jdbc, sql-optimization, examples, spring
