课程名称：现代Java：流聚合器与可扩展并发性 课程概述：本课程旨在为经验丰富的Java开发者提供深入学习现代Stream Gatherers API和虚拟线程的机会，以构建高性能、可扩展的应用程序。建议学员在参加本课程之前具备Java虚拟线程的相关知识。如果您对此不熟悉，可以先参考我的配套课程，打下坚实的基础。Java及其并发工具随着技术的发展而不断演进。通过引入流聚合器和虚拟线程，开发者能够使用熟悉的Stream构造，编写高效、可读且可扩展的I/O管道。本课程实用且现代，旨在帮助您在无需传统线程管理复杂性的情况下，构建真实的并发Java应用程序。 学习内容包括： - 理解Stream Gatherers如何增强Java Stream API - 使用集成器掌握无状态聚合器，实现简单而强大的流转换 - 构建有状态聚合器，处理需要共享或动态上下文的场景 - 实现最终逻辑，用于流结束时的聚合、清理或最终状态转换 - 探索组合器及其在并行流执行中的作用 - 深入了解内置聚合器，学习有效使用的时机和方法 - 编写自定义聚合器，以解锁高级流模式 - 利用虚拟线程处理高并发的I/O任务，减少开销 - 设计并发聚合器，支持执行和结果输出，避免资源耗尽，处理错误而不阻塞其他操作，并允许嵌套并发处理 - 使用流聚合器和虚拟线程构建一项大规模I/O流管道项目，如何高效处理15万次以上的API调用，避免中间集合以提升吞吐量和内存效率，批量写入和流友好的持久化数据 课程价值：许多开发者因复杂性和资源管理的担忧而避免编写高并发代码。通过使用流聚合器和虚拟线程，本课程为简化该过程提供了有效的方案。您将学习如何以可组合的数据管道的视角思考，而不必再关注低级线程或未来关系。通过构建示例和模式，您将在处理真实的I/O密集型用例时充满信心与高效。
Prerequisite: Familiarity with Java Virtual Threads is recommended. If you are new to Virtual Threads, consider checking out my companion course on the topic for a solid foundation.This in-depth course is designed for experienced Java developers looking to master the cutting-edge Stream Gatherers API and unlock the full potential of Virtual Threads for building high-performance, scalable applications.Java has evolved, and so have its concurrency tools. With the introduction of Stream Gatherers and Virtual Threads, you can now write efficient, readable, and scalable I/O pipelines using familiar Stream constructs. This course is practical, modern, and tailored to help you build real-world, concurrent Java applications without the traditional complexity of thread management.What You Will LearnUnderstand how Stream Gatherers enhance the Java Stream APIMaster Stateless Gatherers using integrators for simple yet powerful stream transformationsBuild Stateful Gatherers using initializers for scenarios that require shared or evolving contextImplement Finisher logic for end-of-stream aggregation, cleanup, or final state transformationExplore Combiners and their role in parallel stream executionDeep-dive into built-in gatherers and learn when and how to use them effectivelyWrite your own custom gatherers to unlock advanced stream patternsUse Virtual Threads to handle high-volume I/O-bound tasks with minimal overheadDesign Concurrent Gatherers that:Execute and emit resultsSupport Concurrency Limits to avoid resource exhaustionHandle errors without blocking other operations (e.g. Delay Error pattern)Allow Nested Concurrent Processing for multi-stage, multi-level pipelinesBuild a Massive I/O Stream Pipeline project using Stream Gatherers + Virtual ThreadsIngest 150K+ API calls efficiently with lightweight concurrencyAvoid intermediate collection for better throughput and memory efficiencySave data with batched writes and stream-friendly persistenceWhy Take This Course?Many developers avoid writing high-concurrency code because of complexity and fear of resource management. This course changes that by using Stream Gatherers and Virtual Threads to simplify the process.You will learn how to think in terms of composable data pipelines rather than low-level threads or futures. The examples and patterns you build will help you tackle real I/O-heavy use cases with confidence and performance.
