Java Virtual Threads: Deep Dive into Mounting/Unmounting & Carrier Threads Explained

🚀 Java Virtual Threads Internals: MOUNTING, UNMOUNTING & Carrier Threads Explained 🚀 Ever wondered how Java Virtual Threads achieve such high concurrency without consuming massive resources? The magic lies in the Mounting & Unmounting process onto Carrier Threads! In this deep-dive tutorial, we peel back the layers of the JVM to see exactly how this revolutionary concurrency model works under the hood. 🎓 SPECIAL OFFER: Enroll in my complete Java Virtual Threads & Structured Concurrency with Spring Boot course on Udemy at a discount!

Act early! --- WHAT YOU'LL LEARN IN THIS VIDEO: ✅ THE CORE CONCEPTS: Understand the difference between OS Threads, Platform Threads, and Virtual Threads. ✅ THE SCHEDULERS: How the OS Scheduler (preemptive) differs from the JVM Virtual Thread Scheduler (collaborative). ✅ CARRIER THREADS DEMYSTIFIED: What the ForkJoinPool scheduler is, its default size, and how to configure it (jdk.virtualThreadScheduler.parallelism). ✅ MOUNTING & UNMOUNTING: See a live coding example of how a Virtual Thread mounts on a Carrier Thread, unmounts on blocking operations (like Thread.sleep or I/O), and remounts on a potentially different thread. ✅ I/O VS. CPU-BOUND TASKS: CRITICAL DIFFERENCE! Learn why I/O operations trigger unmounting (enabling massive scalability) while CPU-intensive operations can lead to PINNING and block the Carrier Thread. ✅ LIVE CODE DEMO: Watch me debug a Java application to inspect Virtual Thread states, Carrier Thread names, and the ForkJoinPool in real-time. ✅ JVM INTERNALS: A peek into the VirtualThread.sleepNanos() and Continuation.yield() methods that make unmounting possible. --- TECHNOLOGIES & CONCEPTS COVERED: Java 21+ Virtual Threads (Project Loom) JVM Scheduler (ForkJoinPool) Carrier Threads & Platform Threads Mounting, Unmounting, and Remounting Blocking Operations vs. CPU-intensive Workloads JDK System Properties for Configuration Basic Debugging with an IDE --- KEY TAKEAWAYS: Virtual Threads are lightweight (~1-2KB) and are scheduled by the JVM, not the OS. They UNMOUNT from their Carrier Thread during blocking operations, freeing it up for other tasks. This is the secret to their efficiency. The Carrier Thread pool size defaults to your number of CPU cores but can be configured. There is NO AFFINITY between a Virtual Thread and a Carrier Thread; it can be different after every remount. CPU-INTENSIVE TASKS DO NOT TRIGGER UNMOUNTING, which is crucial for understanding performance implications. --- READY TO MASTER VIRTUAL THREADS COMPLETELY?
