Virtual Threads and Project Loom
Explore how Project Loom and virtual threads transform Java multi-threading by allowing numerous concurrent tasks without heavy system overhead. Understand the practical use of virtual threads with modern ExecutorService, enhancing scalability and efficiency for I/O-bound workloads while balancing computation needs.
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.
Let’s look at how virtual threads work and how they solve ...
