Java Virtual Threads 

01:10 Now it's possible to have millions of Java processes running concurrently. 04:28 Traditional threads are expensive, the solution could be asynchronous programming, but asynchronous programming has very intrusive downsides. 06:35 Project Loom tries to make Threads cheaper. 06:38 What is a Virtual Thread? Conclusion: they feel like normal Threads, it allows you not to care about the details underneath. 07:38 We call traditional Threads, Platform Threads. 08:39 Virtual Thread builder example and newVirtualThreadPerTaskExecutor() example. 09:26 Virtual Threads x Platform Threads x Sequential Benchmark. 12:15 Real Application Benchmark data. The higher the bar, the better the framework scores. 15:35 Little's Law, it works for stable systems, not for systems which continually grow. An example on how Thread-per-Request was their bottleneck in an application. 18:26 Little's Law Chart, Platform Threads x Virtual Threads throughput. 19:39 How to adopt Virtual Threads. Write synchronous code inside the task, as boring and as straightforward possible. 21:02 You should NOT pool Virtual Threads. If you need to pool, or rather limit async execution, use the Semaphore class. 22:10 Don't cache in ThreadLocals. Instead use Scoped Values. 24:10 Avoid pinning. 28:24 (end) How to adopt Virtual Threads frame. 28:54 Structured Concurrency, short intro. For Spring enthusiasts, an interesting blog post: spring.io/blog/2022/10/11/embracing-virtual-threads. This post shows how you can change the Thread-per-Request executor to a newVirtualThreadPerTaskExecutor.

Молодец, Серёга, хорошо объяснил !

Very informative and detailed! This talk can serve as a good summary as to why/when you should use VT.

Will be great when we can write performant concurrent code with this. Had to debug some Spring Webflux / Reactive stuff lately and it was not easy.

Will you introduce API to offer control over which executor a virtual thread should run on?

Cool T-shirt !! ... Cool talk !! 👍😎

Another language mojo is coming in the AI machine learning space, valhalla should come early or some struct like construct along with vector APIs otherwise java could never take off for AI/Machine learning space.

Thank you for informative videos

Very informative

really good talk
