The Java Sessions: Virtual Threads, Scoped Values, and Structured Concurrency

Java 21 introduced Virtual Threads as part of Project Loom, making thread-per-task programming practical at scale. Virtual Threads are lightweight, inexpensive to create, and eliminate the need for complex asynchronous/reactive code in many cases. Alongside Virtual Threads, Structured Concurrency, and Scoped Values, these features simplify the management of concurrent tasks and context. In this session, we’ll explore how these new features change the way we write concurrent Java code and what it means for existing libraries and frameworks.

  • What is a Virtual Thread
  • Creating and Using a Virtual Thread
  • What will Loom's Virtual Threads do to Future and Reactive
  • What is Structured Concurrency?
  • What are Scoped Values?
