Reactive Programming: The Must-Have Skill for Every Microservices Developer

Enter Reactive Programming. It’s not just a buzzword — it’s a game-changer.

In today’s digital landscape, applications must handle massive data volumes, provide real-time responses, and scale efficiently. Traditional synchronous architectures often struggle to meet these demands. Reactive programming addresses these challenges by offering a non-blocking, asynchronous, and event-driven model that significantly improves performance and resource utilization. Lets understand reactive prograaming in deep.

What is Reactive Programming?

Reactive programming is a programming style that focuses on reacting to data changes and events rather than passively waiting for them. It enables applications to handle tasks asynchronously and non-blockingly, improving performance and resource utilization.

Let’s Understand it with a Simple Analogy

Imagine you have a web application that receives user requests. For each request, the app needs to perform some I/O operations — like calling an external web service or querying a database. After the I/O operation, the API also needs to perform additional tasks that are independent of the I/O process. But here’s the catch, performance bottlenecks…
