Traducción al español en progresoEl contenido detallado de esta lección aún se está traduciendo. Mientras tanto, se muestra en inglés.

Create a Mono that simulates a slow service by delaying 5 seconds. Apply a timeout of 1 second and provide a fallback value "Timeout fallback" using onErrorReturn. Subscribe and print.

Note: For Piston execution, simulate with Mono.delay and .timeout().

Timeout with Fallback

Create a Mono that simulates a slow service by delaying 5 seconds. Apply a timeout of 1 second and provide a fallback value "Timeout fallback" using onErrorReturn. Subscribe and print.

Note: For Piston execution, simulate with Mono.delay and .timeout().

Why this works

timeout() sets a maximum time to wait for the next signal. If the timeout expires, it emits a TimeoutException. Combined with onErrorReturn(), this creates a resilient pattern that provides a fallback for slow services.

Expected output
