Build reactive controllers in Spring WebFlux by defining endpoints with Kotlin `suspend` functions and returning `Flow` types. This integration handles asynchronous operations non-blocking, ensuring efficient I/O and responsive services.

Handle reactive database access in Spring WebFlux using R2DBC repositories. R2DBC provides a non-blocking, reactive connection to interact with databases, ensuring efficient concurrent data operations without blocking threads.

Yes, you can stream real-time data to multiple clients using Server-Sent Events (SSE) with Spring WebFlux. Implement non-blocking endpoints returning `Flow` to efficiently handle concurrent SSE connections.

Spring WebFlux supports non-blocking HTTP client calls using WebClient. WebClient facilitates asynchronous inter-service communication, preventing thread blocking and maintaining high concurrency in reactive microservices.

Manage structured concurrency and error handling in reactive Spring applications using Kotlin Coroutines. The skill provides conventions for `Flow` patterns and robust error handling strategies tailored for asynchronous reactive environments.

You need Kotlin Coroutines for Spring WebFlux when building high-concurrency, non-blocking applications. Coroutines simplify complex asynchronous logic and structured concurrency compared to traditional callback or reactive stream approaches.
