Udemy – Modern Java: Stream Gatherers & Scalable Concurrency 2025-7

Modern Java: Stream Gatherers & Scalable Concurrency. This course is designed for experienced Java developers to build highly efficient and scalable applications using Stream Gatherers and Virtual Threads. Java has evolved, and so have its concurrency tools. With the introduction of Stream Gatherers and Virtual Threads, it is now possible to write efficient, readable, and scalable I/O pipelines using familiar Stream constructs. This practical, modern course addresses your needs for building real-world Java concurrent applications without the complexities of traditional thread management. Participants will learn how Stream Gatherers enhance the Java Stream API, use Stateless Gatherers for simple yet powerful transformations, and implement Stateful Gatherers for complex scenarios. They will also learn how to implement Finishers for final aggregation, examine Combiners in parallel streams, and use built-in Gatherers. Writing custom Gatherers for advanced patterns, using Virtual Threads to handle high-volume I/O tasks, and designing concurrent Gatherers for multi-stage processing are other topics covered in this course. By the end, participants will have built a large I/O pipeline project that processes over 150,000 API calls with light concurrency, avoids intermediate gathering, and stores data in stream-compatible ways.

What you will learn

• Build advanced data pipelines using the new Stream Gatherers API in Java.
• Write stateless and stateful gatherers to control stream flow with custom logic.
• Virtual Threads integration for highly scalable I/O-bound processing.
• Design non-blocking concurrent gatherers that publish results as soon as they complete.
• Control concurrency levels to prevent overloading using concurrency-limiting gatherers.
• Manage errors appropriately without disrupting the stream using error delay patterns.
• Implementing nested concurrency in a structured and maintainable way.
• Improved performance and memory consumption with stream-first design and no intermediate sets.

This course is suitable for people who:

• Experienced Java developers: Those who are familiar with Java fundamentals including Streams, Lambdas, and core concurrency concepts.
• Modern Java Adopters: Developers who are eager to use the latest Java features.
• Architects and team leaders: People responsible for designing flexible, efficient, and scalable Java architectures.
