#structuredconcurrency — Public Fediverse posts

Adding an LLM is easy. Building a reliable AI system isn't. Damiana Nascimento shows how Spring AI and Java 26 simplify orchestration, concurrency and observability for production AI.

“Can I block here?” With #Java26, the answer is increasingly yes. #VirtualThreads & #StructuredConcurrency reduce the need for callback-heavy code & oversized thread pools.

Damiana Nascimento explains what modern #JVM-first design looks like: https://javapro.io/2026/05/06/java-26-in-practice-how-the-jvm-is-changing-the-way-we-write-code/

Ever seen requests fail while subtasks kept running anyway? That’s one of the nastiest problems in concurrent systems — especially with #VirtualThreads. Babneet Singh maps out how #StructuredConcurrency in #Java26 adds clear task ownership & teardown: https://javapro.io/2026/06/09/structured-concurrency-in-java-26-jep-525-deep-dive/

Still handling cancellation, timeouts & fallback logic manually across concurrent tasks? That’s usually where distributed systems become unpredictable under load.

#Concurrency bugs rarely fail loudly — they leak resources, stall requests, & waste CPU. @BalaRawool demonstrates how #StructuredConcurrency can short-circuit failures and keep workflows consistent in #SpringBoot.

ThreadLocal breaks with #VirtualThreads. @chwoerz explains why — and how ScopedValue replaces it with safe, immutable, scope-bound context propagation. Migrating to #Java25?

Still fighting thread pools when traffic spikes? #ProjectLoom offers a different path. @BalaRawool shows how #VirtualThreads, #StructuredConcurrency, and Scoped Values work together in a real #SpringBoot app.

#Performance

Thread leakage is the silent killer of “quick parallelization.” #StructuredConcurrency makes sure child tasks end with the parent scope—by design.

Do you still need reactive programming for high throughput? @chwoerz shows how #VirtualThreads + #StructuredConcurrency handle fan-out calls cleanly and synchronously.

#Java25

Ok, to follow up on yesterday's structured concurrency question:

In Python, I have a hypothetical HTTP client:

async with HTTP() as client:
http.get("https://site.example/index.html")

and it handles things like HTTP/2 multiplexing and connection pools and stuff. So it needs some background tasks to coordinate and maintain them.

Classically, I'd call these "daemon tasks" (after Python's daemon threads).

But I feel like I'm missing something?

#VirtualThreads scale concurrency—but they don’t fix structure or error handling. @chwoerz shows how StructuredTaskScope and ScopedValue complete the picture in #Java25. Want safer, faster concurrent code?

Still making sequential remote calls even with #VirtualThreads? @chwoerz explains how StructuredTaskScope cuts latency by running tasks concurrently—without reactive complexity. Curious how it works?

Really nice #jfall talk on @quarkusio and concurrency #java #StructuredConcurrency

Nebenläufigkeit in #Java war oft mit Komplexität und Overhead verbunden. #Java21 bricht mit alten Konzepten und bringt Werkzeuge wie #StructuredConcurrency.

@openjdk

#Java 21 introduces #VirtualThreads, but the real shift lies deeper: #StructuredConcurrency & Scoped Values redefine how we write parallel code. Merlin Bögershausen breaks it down — with live code examples.

#JVM @openjdk

#Java 25 may redefine StructuredTaskScope before it goes final. Until then, developers face a moving target—with clear benefits & shifting syntax. Ron Veen outlines the state of #StructuredConcurrency.
