Creating a Million Virtual Threads Using Project Loom by A N M Bazlur Rahman

Project loom introduces virtual threads, lightweight threads that aim to dramatically reduce the effort of writing, maintaining, and monitoring high-throughput concurrent applications with the Java platform.

We need threads to achieve high throughput. However, threads are not cheap and limited in number. To get around this problem, various alternatives such as a reactive programming style have emerged. These techniques bypass creating a lot of threads but debugging becomes more difficult. This makes developers grumpy. However, with virtual threads, we no longer have to look for alternatives, which would make developers happy again.

This talk will explore what virtual threads are, how they are implemented, how they solve our modern problems and if there are any shortcomings.
