End-to-End System Design in Spring Boot with an Efficient Reactive Framework
Introduction
As modern applications demand high throughput, low latency, and efficient resource utilization, traditional synchronous architectures may fall short. A reactive approach in Spring Boot, using Spring WebFlux and Project Reactor, provides a non-blocking, event-driven model for handling high concurrency with minimal resource consumption.
This blog presents a step-by-step guide to designing an efficient end-to-end system in Spring Boot with a Reactive Framework.
Key Components of a Reactive System
- Reactive Programming Paradigm — Event-driven, non-blocking, and backpressure-supported.
- Spring WebFlux — A reactive alternative to Spring MVC.
- Reactive Data Access — Using R2DBC for relational databases or MongoDB Reactive Streams for NoSQL.
- Messaging with Kafka or RabbitMQ — Efficient event-driven communication.
- Reactive Security — Non-blocking authentication and authorization.
- Observability — Metrics and logging with Micrometer & Prometheus.
Step 1: Setting Up Spring Boot with WebFlux
Create a new Spring Boot project with the following dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>…
