Reactive Spring Boot for scalable microservices
Key Questions
What is the difference between Spring WebFlux and Loom for reactive apps?
Spring WebFlux provides non-blocking reactive programming for scalable microservices, contrasting with Loom's virtual threads. Benchmarks compare DB/Kafka/HTTP/Redpanda/Cloud Stream RabbitMQ performance.
How does hybrid sync/async work in reactive Spring Boot microservices?
Hybrid approaches mix REST/events with Feign/WebClient for sync/async operations. They support scalable designs with non-blocking I/O versus blocking patterns.
What design patterns apply to reactive Spring Boot microservices?
Essential patterns include API Gateway, Circuit Breaker, and event-driven architectures for security, maintainability, and fault tolerance. Tools like Redpanda enable scalable event-driven systems.
