Structured Concurrency - Hierarchical Cancellation and Error Handling

Learn structured concurrency principles and implementation patterns through this comprehensive conference talk that explores hierarchical cancellation and error handling across multiple programming languages. Discover how structured concurrency simplifies fan-out and fan-in use cases, particularly for racing scenarios where sub-tasks require cancellation or error management. Explore practical approaches using Java (with and without Project Loom), Kotlin, and Scala through seven detailed scenarios that demonstrate real-world concurrency challenges. Master the fundamentals of structured concurrency concepts, examine racing patterns, and work through hands-on demonstrations using the "Easy Racer" example project. Compare different implementation strategies across languages and frameworks, including Java with Jox, Kotlin with Coroutines and Splitties, and Scala with Ox and ZIO. Understand how to handle race shutdown scenarios on both success and error conditions, and gain insights into managing complex concurrent operations with proper cancellation semantics. Benefit from live coding demonstrations, detailed scenario walkthroughs, and expert guidance on choosing the right concurrency approach for your specific use case, whether you're new to concurrent programming or looking to modernize existing concurrent code with structured patterns.
