        public io.smallrye.mutiny.Uni<V> replace​(K k,
                                         V v,
                                         long ttl)
        Replace the entry only if it is currently mapped to some value

        Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.

        Parameters:
        k - the key
        v - the new value
        ttl - The time to live (in ms) for the entry
        Returns:
        the uni firing the result of the operation when completed, or a failure if the operation failed.
