Reactive Programming with Java
In the past few years, reactive programming has developed increasingly as an alternative to classic programming models. Especially in the area of highly scalable applications, reactive programming offers advantages in terms of performance and reliability.
Reactive programming is able to recognize the load of an application during operation and to adapt the operation depending on the load. Especially in scenarios with high concurrency, the reactive programming model also prevents most classic errors caused by multi-threading.
Reactive programming is defined as message-based in the Reactive manifest. This encapsulation facilitates a clearly defined public interface, which hides the internal workings of larger modules and allows applications to be efficiently split into Microservices.
- Understand the basic advantages of reactive programming within a short period of time
- Gain practical knowledge for applying reactive frameworks in everyday life based on examples
As a developer, consultant or project manager, you want to learn about reactive programming and understand the advantages and disadvantages. You value being able to create Reactive programs both theoretically as well as using practical examples.
- What are the goals of reactive programming?
- What is the problem of traditional architectures?
- Why do reactive applications scale better?
- When is reactive programming the correct model?
- Basic building blocks: Subscriber, Publisher, Observable
- Overview of the frameworks (Project Reactor & RxJava)
Basics of reactive programming
- Generation of observables
- Difference between hot and cold observables
- Subscribing and unsubscribing
- Merge and Concat
- Merging with conditions
- Troubleshooting during processing
- Return, Resume and Repeat
- “Backpressure” example
- “RestService” example
- Simple message-based service
Spring in detail
- Spring Webflux
- Spring Data Reactive
- Spring Web clients
Advanced topics (optional)
- Integration with legacy systems
- Swing/JavaFx/SWT/Android integration
- Reactive interoperation Vert.x with RxJava and Spring 5
