+[[kafka-dlq-processing]]
+== Dead-Letter Topic Processing
+
+Because it can't be anticipated how users would want to dispose of dead-lettered messages, the framework does not provide any standard mechanism to handle them.
+If the reason for the dead-lettering is transient, you may wish to route the messages back to the original topic.
+However, if the problem is a permanent issue, that could cause an infinite loop.
+The following `spring-boot` application is an example of how to route those messages back to the original topic, but moves them to a third "parking lot" topic after three attempts.
+The application is simply another spring-cloud-stream application that reads from the dead-letter topic.
+It terminates when no messages are received for 5 seconds.
+
+The examples assume the original destination is `so8400out` and the consumer group is `so8400`.
+
+There are several considerations.
+
+- Consider only running the rerouting when the main application is not running.
+Otherwise, the retries for transient errors will be used up very quickly.
+- Alternatively, use a two-stage approach - use this application to route to a third topic, and another to route from there back to the main topic.
+- Since this technique uses a message header to keep track of retries, it won't work with `headerMode=raw`.
+In that case, consider adding some data to the payload (that can be ignored by the main application).
+- `x-retries` has to be added to the `headers` property `spring.cloud.stream.kafka.binder.headers=x-retries` on both this, and the main application so that the header is transported between the applications.
+- Since kafka is publish/subscribe, replayed messages will be sent to each consumer group, even those that successfully processed a message the first time around.

+Kafka binder module exposes the following metrics:

+`spring.cloud.stream.binder.kafka.someGroup.someTopic.lag`  - this metric indicates how many messages
+have not been yet consumed from given binder's topic (`someTopic`) by given consumer group (`someGroup`).
+For example if the value of the metric `spring.cloud.stream.binder.kafka.myGroup.myTopic.lag` is `1000`, then
+consumer group `myGroup` has `1000` messages to waiting to be consumed from topic `myTopic`. This metric is

+== Kafka Streams Binding Capabilities of Spring Cloud Stream
 
+Spring Cloud Stream Kafka support also includes a binder specifically designed for Kafka Streams binding.
+Using this binder, applications can be written that leverage the Kafka Streams API.
+For more information on Kafka Streams, see https://kafka.apache.org/documentation/streams/developer-guide[Kafka Streams API Developer Manual]
+
+Kafka Streams support in Spring Cloud Stream is based on the foundations provided by the Spring Kafka project. For details on that support, see https://docs.spring.io/spring-kafka/reference/html/_reference.html#kafka-streams[Kafaka Streams Support in Spring Kafka].
+
+Here are the maven coordinates for the Spring Cloud Stream KStream binder artifact.
+
+[source,xml]
+----
+<dependency>
+  <groupId>org.springframework.cloud</groupId>
+  <artifactId>spring-cloud-stream-binder-kstream</artifactId>
+</dependency>
+----
+
+In addition to leveraging the Spring Cloud Stream programming model which is based on Spring Boot, one of the main other benefits that the KStream binder provides is the fact that it avoids the boilerplate configuration that one needs to write when using the Kafka Streams API directly.
+High level streams DSL provided through the Kafka Streams API can be used through Spring Cloud Stream in the current support.
+
+=== Usage example of high level streams DSL
+
+This application will listen from a Kafka topic and write the word count for each unique word that it sees in a 5 seconds time window.
+
+[source]
+----
+@SpringBootApplication
+@EnableBinding(KStreamProcessor.class)
+public class WordCountProcessorApplication {
+
+	@StreamListener("input")
+	@SendTo("output")
+	public KStream<?, String> process(KStream<?, String> input) {
+		return input
+				.flatMapValues(value -> Arrays.asList(value.toLowerCase().split("\\W+")))
+				.map((key, word) -> new KeyValue<>(word, word))
+				.groupByKey(Serdes.String(), Serdes.String())
+				.count(TimeWindows.of(5000), "store-name")
+				.toStream()
+				.map((w, c) -> new KeyValue<>(null, "Count for " + w.key() + ": " + c));
+	}
+
+	public static void main(String[] args) {
+		SpringApplication.run(WordCountProcessorApplication.class, args);
+	}
+----
+
+If you build it as Spring Boot runnable fat jar, you can run the above example in the following way:
+
+[source]
+----
+java -jar uber.jar  --spring.cloud.stream.bindings.input.destination=words --spring.cloud.stream.bindings.output.destination=counts
+----
+
+This means that the application will listen from the incoming Kafka topic words and write to the output topic counts.
+
+Spring Cloud Stream will ensure that the messages from both the incoming and outgoing topics are bound as KStream objects.
+As one may observe, the developer can exclusively focus on the business aspects of the code, i.e. writing the logic required in the processor rather than setting up the streams specific configuration required by the Kafka Streams infrastructure.
+All those boilerplate is handled by Spring Cloud Stream behind the scenes.
+
+=== Support for interactive queries
+
+If access to the `KafkaStreams` is needed for interactive queries, the internal `KafkaStreams` instance can be accessed via `KStreamBuilderFactoryBean.getKafkaStreams()`.
+You can autowire the `KStreamBuilderFactoryBean` instance provided by the KStream binder. Then you can get `KafkaStreams` instance from it and retrieve the underlying store, execute queries on it, etc.
+
+=== Kafka Streams properties
+
+configuration::
+  Map with a key/value pair containing properties pertaining to Kafka Streams API.
+  This property must be prefixed with `spring.cloud.stream.kstream.binder.`.
+
+ Following are some examples of using this property.
+
+[source]
+----
+spring.cloud.stream.kstream.binder.configuration.key.serde=org.apache.kafka.common.serialization.Serdes$StringSerde
+spring.cloud.stream.kstream.binder.configuration.value.serde=org.apache.kafka.common.serialization.Serdes$StringSerde
+spring.cloud.stream.kstream.binder.configuration.commit.interval.ms=1000
+----
+
+  For more information about all the properties that may go into streams configuration, see StreamsConfig JavaDocs.
+
+There can also be binding specific properties.
+
+For instance, you can use a different Serde for your input or output destination.
+
+[source]
+----
+spring.cloud.stream.kstream.bindings.output.producer.keySerde=org.apache.kafka.common.serialization.Serdes$IntegerSerde
+spring.cloud.stream.kstream.bindings.output.producer.valueSerde=org.apache.kafka.common.serialization.Serdes$LongSerde
+----
+
+[[kafka-error-channels]]
+== Error Channels
+
+Starting with _version 1.3_, the binder unconditionally sends exceptions to an error channel for each consumer destination, and can be configured to send async producer send failures to an error channel too.
+See <<binder-error-channels>> for more information.
+
+The payload of the `ErrorMessage` for a send failure is a `KafkaSendFailureException` with properties:
+
+* `failedMessage` - the spring-messaging `Message<?>` that failed to be sent.
+* `record` - the raw `ProducerRecord` that was created from the `failedMessage`
+
+There is no automatic handling of these exceptions (such as sending to a <<kafka-dlq-processing, Dead-Letter queue>>); you can consume these exceptions with your own Spring Integration flow.
