High‑Performance Java Persistence Training

Introduction

High‑performance Java persistence training is designed to help Java developers master the art of writing efficient, scalable, and maintainable persistence code using JPA and Hibernate. In this course, you will learn how to minimize database roundtrips, prevent common performance pitfalls, and leverage caching and batching strategies to build high-throughput persistence layers.

Why This Course Matters

• Optimize your application’s ORM layer to handle large volumes of data.
• Reduce latency and improve response times by tuning fetch strategies.
• Use caching (first-level, second-level) effectively to minimize SQL hits.
• Leverage batch processing to perform bulk operations efficiently.
• Troubleshoot N+1 problems, memory leaks, and long-lived sessions.
• Profile and monitor persistence performance using real metrics.

Who Should Attend

This course is ideal for:

• Java developers building enterprise applications with JPA/Hibernate.
• Architects who design data access layers and want to ensure performance.
• Backend engineers working with Spring Data JPA or custom ORM layers.
• Anyone who has basic JPA or Hibernate experience and wants to go deeper.

Prerequisites

To get the most out of this training, you should have:

• Intermediate to advanced knowledge of Java.
• Basic familiarity with JPA (Jakarta Persistence) or Hibernate.
• A working development environment (IDE, database, etc.).

Course Format & Duration

The training is structured as a mix of:

• Lectures & deep-dive conceptual sessions
• Hands-on labs & code exercises
• Real-world performance tuning scenarios
• Q&A and troubleshooting clinics

Total duration: 16–24 hours (depending on lab depth and participant pace)

Syllabus / Topics Covered

1. 1. Introduction to Java Persistence & ORM Architecture
      Overview of JPA, Hibernate, and other ORM frameworks. :contentReference[oaicite:0]{index=0}
   2. Fetch Strategies: Lazy, Eager & Batch Loading
      When and how to use `LAZY` vs `EAGER`, batch fetching via `@BatchSize` or `@Fetch`, to avoid N+1 queries. :contentReference[oaicite:1]{index=1}
   3. Caching Strategies
      Understanding first-level vs second-level cache, configuring cache providers (e.g., Ehcache), cache concurrency strategies. :contentReference[oaicite:2]{index=2}
   4. Batch Processing & Bulk Operations
      Using `hibernate.jdbc.batch_size`, flush/clear patterns, and stateless sessions for bulk inserts/updates. :contentReference[oaicite:3]{index=3}
   5. Session & Transaction Management
      Best practices for opening/closing sessions, defining transaction boundaries, read-only transactions. :contentReference[oaicite:4]{index=4}
   6. Mapping Design & Schema Optimization
      Mapping strategies (e.g., `@DynamicUpdate`, `@SelectBeforeUpdate`), LOB handling, avoiding overly complex relationships. :contentReference[oaicite:5]{index=5}
   7. Profiling, Monitoring & Metrics
      Using Hibernate statistics, logging SQL, analyzing cache hit ratios, and tuning based on real performance data. :contentReference[oaicite:6]{index=6}

\item Advanced Topics & Best Practices
Techniques like `@EntityGraph`, query tuning via JOIN FETCH, using query cache, and avoiding dirty-checking overhead. :contentReference[oaicite:7]{index=7}

Learning Outcomes

By the end of this training, you will be able to:

• Design and configure your persistence layer for high performance.
• Choose optimal fetching strategies to minimize database round-trips.
• Implement effective caching to reduce load on the database.
• Execute batch operations efficiently without memory issues.
• Monitor and profile your persistence code to identify bottlenecks.
• Apply best practices and advanced patterns to production-grade applications.
