Virtual Threads

Lightweight threads (Project Loom) for massive concurrency.

Virtual Threads Overview

Virtual threads (Project Loom) provide lightweight threads that allow creating a large number of concurrent tasks without the resource overhead of platform threads. They simplify writing concurrent code by keeping familiar blocking APIs while scaling efficiently.

Key Points

  • Use virtual threads for high-concurrency I/O-bound workloads
  • Integrates with existing executors via Executors.newVirtualThreadPerTaskExecutor()
  • Testing and migration considerations for libraries and blocking code
