Virtual Threads and Project Loom
Explore how Project Loom introduces virtual threads to overcome scalability limits of traditional platform threads in Java. Understand the mechanics of virtual threads, how they reduce resource consumption, and the role of the modern ExecutorService for efficient task management. Learn when to apply virtual threads for I/O-bound workloads and platform threads for heavy computations to optimize performance and simplify application design.
We'll cover the following...
Applications with large numbers of concurrent tasks were previously constrained by the cost of platform threads. Traditional Java platform threads typically map one-to-one to operating system threads, which are relatively expensive to create and maintain, consume stack memory, and incur context-switching overhead. Project Loom introduced virtual threads, allowing many concurrent tasks to run without requiring a dedicated operating system thread for each task. ...
