## Health v2 (maintenance only)
Score: 72/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 89, release rhythm 35, longevity 100
- inputs: {"age_days": 3975, "days_push": 71, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Code examples accompanying the High-Performance Java Persistence book and video course by Vlad Mihalcea. It demonstrates JDBC, JPA, Hibernate, and jOOQ patterns and serves as a testbed for measuring Java data-access layer performance.

## Use cases
- learn how to optimize JPA and Hibernate performance
- test JDBC or jOOQ query performance in Java
- find examples of efficient entity mappings and relationships
- study database transaction and concurrency patterns in Java
- benchmark different Java persistence strategies
- prepare for Java persistence interview or training

## When to choose
- you are learning or teaching high-performance data access on the JVM
- you want runnable examples to accompany the book or video course
- you need a harness to test JPA, Hibernate, JDBC, or jOOQ behavior

## When to avoid
- you need a production-ready ORM library rather than educational examples
- your project does not use the JVM or Java persistence stack
- you want an automated performance-optimization tool like Hypersistence Optimizer

## Facets
- artifact type: learning-resource
- maturity: active
- function: database, orm, testing, benchmarking, developer-tools
- domain: databases, developer-tools, tutorials, performance
- platform: jvm, cross-platform
- tags: jpa, hibernate, jdbc, jooq, book-examples, video-course, database-performance, java
