 Partitioning also maps directly to Apache Kafka partitions as well.

+The binder currently uses the Apache Kafka `kafka-clients` version `3.1.0`.
 This client can communicate with older brokers (see the Kafka documentation), but certain features may not be available.
 For example, with versions earlier than 0.11.x.x, native headers are not supported.
 Also, 0.11.x.x does not support the `autoAddPartitions` property.

 ===== Example: Pausing and Resuming the Consumer
 
 If you wish to suspend consumption but not cause a partition rebalance, you can pause and resume the consumer.
-This is facilitated by adding the `Consumer` as a parameter to your `@StreamListener`.
-To resume, you need an `ApplicationListener` for `ListenerContainerIdleEvent` instances.
+This is facilitated by managing the binding lifecycle as shown in **Binding visualization and control** in the Spring Cloud Stream documentation, using `State.PAUSED` and `State.RESUMED`.
+
+To resume, you can use an `ApplicationListener` (or `@EventListener` method) to receive `ListenerContainerIdleEvent` instances.
 The frequency at which events are published is controlled by the `idleEventInterval` property.
-Since the consumer is not thread-safe, you must call these methods on the calling thread.
-
-The following simple application shows how to pause and resume:
-
-[source, java]

-@SpringBootApplication
-@EnableBinding(Sink.class)
-public class Application {
-
-	public static void main(String[] args) {
-		SpringApplication.run(Application.class, args);
-	}
-
-	@StreamListener(Sink.INPUT)
-	public void in(String in, @Header(KafkaHeaders.CONSUMER) Consumer<?, ?> consumer) {
-		System.out.println(in);
-		consumer.pause(Collections.singleton(new TopicPartition("myTopic", 0)));
-	}
-
-	@Bean
-	public ApplicationListener<ListenerContainerIdleEvent> idleListener() {
-		return event -> {
-			System.out.println(event);
-			if (event.getConsumer().paused().size() > 0) {
-				event.getConsumer().resume(event.getConsumer().paused());
-			}
-		};
