Non-Blocking and Reactive are related concepts in the context of asynchronous programming, but they refer to different aspects of the programming model. This entry explains what each means and how they are different. Disclaimer: This blog was written by ChatGPT with the image by MidJourney.
What is non-blocking?
In Reactor Java, non-blocking refers to the ability of the code to continue executing without waiting for a particular operation to complete. This is achieved by using asynchronous programming techniques, such as callbacks or reactive streams.
In non-blocking programming, when an operation is initiated, the program does not block and wait for the operation to complete. Instead, the program continues to execute and may initiate other operations while waiting for the original operation to complete. Once the original operation completes, a callback is invoked, allowing the program to process the result.
Non-blocking programming is important in environments where many concurrent operations may be occurring, such as web applications or network servers. By using non-blocking programming techniques, these applications can handle many requests simultaneously without becoming blocked or unresponsive. This improves the overall performance and scalability of the application.
Reactor Java is a reactive programming library for building non-blocking applications on the JVM. It provides a range of tools and abstractions for working with reactive streams, allowing developers to easily build scalable and efficient applications.
