Java 21 Virtual Threads and Structured Concurrency

Unlock Scalability with Java Virtual Threads & Spring Boot 3.2.0

Boost application performance and reduce cloud costs with this comprehensive guide to Java Virtual Threads (Project Loom), a revolutionary addition to the Java platform (JDK 21). This course dives deep into leveraging Virtual Threads for highly scalable multithreading applications using Spring Boot 3.2.0.

What are Virtual Threads?

Discover how Virtual Threads address the limitations of traditional Java threads, offering a lightweight alternative that dramatically reduces resource consumption in the cloud. Learn how they enable developers to write non-blocking code sequentially, achieving the same results as complex Reactive programming approaches – simplifying development and optimizing performance.

Key Concepts Covered:

• Virtual Threads vs. Platform Threads: Understand the fundamental differences and why Virtual Threads are a game-changer for scalability.
• Scalability Challenges in Java: Identify the root causes of scalability issues with traditional Java threads.
• Spring Boot 3.2.0 & JDK 21 Integration: Learn how to effectively utilize Virtual Threads within a Spring Boot environment.
• Structured Concurrency: Master Structured Concurrency and its role in writing robust and scalable Java applications.
• Thread Locals vs. Scoped Values: Explore the differences between Thread Locals and Scoped Values for managing thread-specific data.
• Delimited Continuations: Understand how Delimited Continuations are used in conjunction with Virtual Threads.
• Virtual Threads Implementation: Delve into the implementation details of Virtual Threads using Continuations.
• Virtual Threads vs. Reactive Programming: A clear comparison of the two approaches to concurrency.

In this course, you will learn:

• How to increase scalability and dramatically reduce costs using Virtual Threads.
• The reasons behind scalability issues with traditional Java threads.
• How to scale Spring Boot applications to handle 100,000 concurrent users.
• The inner workings of Virtual Threads and their impact on application performance.
• Practical application of Structured Concurrency in Java.
• Effective use of Scoped Values and Thread Locals.
• How to implement Multithreading with Virtual Threads and Structured Concurrency.

What Learners are Saying:

• "Very informative, understandable, and easy to follow. A course I wish existed on Java IO/NIO."
• "Excellent course! Simplified a complex topic."
• "Great explanations with simple diagrams that make Virtual Threads easy to visualize."
• "Good and concise explanation. Looking forward to seeing Virtual Threads in a LTS version."

Bonus Content:

• Java Futures & Completable Futures Refresher: Reinforce your understanding of asynchronous programming concepts.

Important Note: Java Virtual Threads are available in JDK 21. Structured Concurrency and Scoped Value classes are available as Preview features in JDK 21.
