StructuredTaskScope And ScopedValue by Christian Woerz

Ever wanted to squeeze every drop of performance out of Java 21’s virtual threads? Christian Woerz walks you through two super-powerful preview features—StructuredTaskScope and ScopedValue—and shows how they make concurrency a breeze.

In a live-coding session you’ll start with a blank Java app and iteratively build a full-blown, concurrent web application. Along the way you’ll learn why ScopedValues beat ThreadLocals in most cases and how to craft your own StructuredTaskScopes for real-world needs, so you can leave the talk with a rock-solid, hands-on understanding.
