Reactive Programming in Modern Java using Project Reactor

¡Hola! It seems like you're looking for an outline or summary of a course on Project Reactor within the context of reactive programming, possibly using Spring WebFlux. Based on the structure you've provided, here's a detailed breakdown of each section:

Section 15: Making Blocking Calls in MovieReactiveService

In this section, you will learn how to introduce blocking calls into a reactive pipeline using Project Reactor. This includes understanding how to handle blocking operations and integrating them with non-blocking streams.

Section 16: BackPressure

Backpressure is a critical concept in reactive programming that deals with handling the load when the upstream processor pushes more data than the downstream can process. You will learn about different strategies to handle backpressure, including:

• Introduction to BackPressure
• Implementing BackPressure using various operators like onBackpressureDrop(), onBackpressureBuffer(), and onBackpressureError()
• Writing JUnit tests to validate the backpressure behavior

Section 17: Explore Data Parallelism in Project Reactor

In this section, you'll explore how to introduce parallel execution into your reactive pipelines. You will learn about:

• Using parallel() and runOn() operators for parallel processing
• Utilizing the flatmap() operator to handle parallel data streams
• Understanding the difference between flatMapSequential() and flatmap() in the context of parallel processing

Section 18: Cold & Hot Streams

Reactive streams can be categorized as cold or hot based on their behavior. In this section, you will:

• Learn about cold and hot streams and their significance
• Understand how to work with cold streams using operators like cold()
• Explore hot streams and learn how to use ConnectableFlux and its variants

Section 19: JUnit Testing using VirtualTimeScheduler

Testing reactive applications can sometimes be challenging due to their asynchronous nature. In this section, you will:

• Learn about VirtualTimeScheduler for synchronous testing of reactive streams
• Use StepVerifier in conjunction with VirtualTimeScheduler to test your streams

Section 20: Build NonBlocking RestClient using WebClient

In this section, you will create a non-blocking REST client using Spring's WebClient. You will:

• Understand the Reactive Movie API
• Implement a non-blocking MovieInfoService and ReviewService RestClient
• Build out the getAllMovies and getMovieById services using WebClient
• Set up integration tests using WireMock

Section 21: Programmatically Creating a Flux

Reactor provides various ways to create a Flux programmatically. In this section, you will learn about:

• Using the create() method to build complex sequences
• Using the push() method for more control over the sequence creation

Section 22: Debugging in Project Reactor

Debugging reactive applications can be different from traditional applications. In this section, you will:

• Learn how to debug exceptions in reactive streams using "checkpoint" operators like doOnNext() and then()
• Utilize hooks such as Hooks.onOperatorDebug() for deeper insights into the stream processing
• Set up global debugging for production-ready applications using the ReactorDebugAgent

By the end of this course, you should have a comprehensive understanding of reactive programming principles, be able to apply them effectively in your projects, and understand when and how to use different Project Reactor features. This knowledge will enable you to build robust, scalable, and responsive applications with Project Reactor and WebFlux.
