Reactive Spring
summary
Shows a runnable reservation-service built with Spring WebFlux, Reactor and Java 11 that uses Mono/Flux for backpressure and scales without spawning thousands of threads (threads cost ~1MB each, the C10k problem is real). Demonstrates reactive MongoDB driver, swaps to Postgres via R2DBC (manual ConnectionFactory) and exposes SSE endpoints plus an RSocket stream between services. All demos run end to end in the session and successfully persist and stream data.
