public @interface CancellationPolicy
When a future returned from an entry point on a production component is cancelled, the component is cancelled: all producers in the component (including those for other entry points) are cancelled.
When a child component is cancelled, its parent component is not cancelled unless the
parent component is annotated with @CancellationPolicy(fromSubcomponents = PROPAGATE). If
that parent component has a parent (the grandparent of the cancelled child component), it will
not be cancelled unless it also has a @CancellationPolicy annotation allowing
cancellation to propagate to it from subcomponents.
