+== Building
+
+:jdkversion: 1.7
+
+=== Basic Compile and Test
+
+To build the source you will need to install JDK {jdkversion}.
+
+The build uses the Maven wrapper so you don't have to install a specific
+version of Maven. To enable the tests, you should have Kafka server 0.9 or above running
+before building. See below for more information on running the servers.
+
+The main build command is
+
+----
+$ ./mvnw clean install
+----
+
+You can also add '-DskipTests' if you like, to avoid running the tests.
+
+NOTE: You can also install Maven (>=3.3.3) yourself and run the `mvn` command
+in place of `./mvnw` in the examples below. If you do that you also
+might need to add `-P spring` if your local Maven settings do not
+contain repository declarations for spring pre-release artifacts.
+
+NOTE: Be aware that you might need to increase the amount of memory
+available to Maven by setting a `MAVEN_OPTS` environment variable with
+a value like `-Xmx512m -XX:MaxPermSize=128m`. We try to cover this in
+the `.mvn` configuration, so if you find you have to do it to make a
+build succeed, please raise a ticket to get the settings added to
+source control.
+
+
+The projects that require middleware generally include a
+`docker-compose.yml`, so consider using
+http://compose.docker.io/[Docker Compose] to run the middeware servers
+in Docker containers.
+
+=== Documentation
+
+There is a "full" profile that will generate documentation.
+
+=== Working with the code
+If you don't have an IDE preference we would recommend that you use
+http://www.springsource.com/developer/sts[Spring Tools Suite] or
+http://eclipse.org[Eclipse] when working with the code. We use the
+http://eclipse.org/m2e/[m2eclipe] eclipse plugin for maven support. Other IDEs and tools
+should also work without issue.
+
+==== Importing into eclipse with m2eclipse
+We recommend the http://eclipse.org/m2e/[m2eclipe] eclipse plugin when working with
+eclipse. If you don't already have m2eclipse installed it is available from the "eclipse
+marketplace".
+
+Unfortunately m2e does not yet support Maven 3.3, so once the projects
+are imported into Eclipse you will also need to tell m2eclipse to use
+the `.settings.xml` file for the projects.  If you do not do this you
+may see many different errors related to the POMs in the
+projects.  Open your Eclipse preferences, expand the Maven
+preferences, and select User Settings.  In the User Settings field
+click Browse and navigate to the Spring Cloud project you imported
+selecting the `.settings.xml` file in that project.  Click Apply and
+then OK to save the preference changes.
+
+NOTE: Alternatively you can copy the repository settings from https://github.com/spring-cloud/spring-cloud-build/blob/master/.settings.xml[`.settings.xml`] into your own `~/.m2/settings.xml`.
+
+==== Importing into eclipse without m2eclipse
+If you prefer not to use m2eclipse you can generate eclipse project metadata using the
+following command:
+
+[indent=0]
+----
+	$ ./mvnw eclipse:eclipse
+----
+
+The generated eclipse projects can be imported by selecting `import existing projects`
+from the `file` menu.

+[[contributing]
+== Contributing
+
+Spring Cloud is released under the non-restrictive Apache 2.0 license,
+and follows a very standard Github development process, using Github
+tracker for issues and merging pull requests into master. If you want
+to contribute even something trivial please do not hesitate, but
+follow the guidelines below.
+
+=== Sign the Contributor License Agreement
+Before we accept a non-trivial patch or pull request we will need you to sign the
+https://support.springsource.com/spring_committer_signup[contributor's agreement].
+Signing the contributor's agreement does not grant anyone commit rights to the main
+repository, but it does mean that we can accept your contributions, and you will get an
+author credit if we do.  Active contributors might be asked to join the core team, and
+given the ability to merge pull requests.
+
+=== Code Conventions and Housekeeping
+None of these is essential for a pull request, but they will all help.  They can also be
+added after the original pull request but before a merge.
+
+* Use the Spring Framework code format conventions. If you use Eclipse
+  you can import formatter settings using the
+  `eclipse-code-formatter.xml` file from the
+  https://github.com/spring-cloud/build/tree/master/eclipse-coding-conventions.xml[Spring
+  Cloud Build] project. If using IntelliJ, you can use the
+  http://plugins.jetbrains.com/plugin/6546[Eclipse Code Formatter
+  Plugin] to import the same file.
+* Make sure all new `.java` files to have a simple Javadoc class comment with at least an
+  `@author` tag identifying you, and preferably at least a paragraph on what the class is
+  for.
+* Add the ASF license header comment to all new `.java` files (copy from existing files
+  in the project)
+* Add yourself as an `@author` to the .java files that you modify substantially (more
+  than cosmetic changes).
+* Add some Javadocs and, if you change the namespace, some XSD doc elements.
+* A few unit tests would help a lot as well -- someone has to do it.
+* If no-one else is using your branch, please rebase it against the current master (or
+  other target branch in the main project).
+* When writing a commit message please follow http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions],
+  if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit
+  message (where XXXX is the issue number).

+== Dead-Letter Topic Processing
+
+Because you cannot anticipate 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 sample Spring Boot application within this topic is an example of how to route those messages back to the original topic, but it moves them to a "`parking lot`" topic after three attempts.
+The application is 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 a couple of strategies to consider:
+
+* Consider running the rerouting only when the main application is not running.
+Otherwise, the retries for transient errors are 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.
+
+The following code listings show the sample application:

+== Usage
+
+For using the Kafka Streams binder, you just need to add it to your Spring Cloud Stream application, using the following 
+Maven coordinates:
+
+[source,xml]
+----
+<dependency>
+  <groupId>org.springframework.cloud</groupId>
+  <artifactId>spring-cloud-stream-binder-kafka-streams</artifactId>
+</dependency>
+----
+
+== Kafka Streams Binder Overview
+
+Spring Cloud Stream's Apache Kafka support also includes a binder implementation designed explicitly for Apache Kafka 
+Streams binding. With this native integration, a Spring Cloud Stream "processor" application can directly use the 
+https://kafka.apache.org/documentation/streams/developer-guide[Apache Kafka Streams] APIs in the core business logic.
+
+Kafka Streams binder implementation builds on the foundation provided by the http://docs.spring.io/spring-kafka/reference/html/_reference.html#kafka-streams[Kafka Streams in Spring Kafka] 
+project.
+
+As part of this native integration, the high-level https://docs.confluent.io/current/streams/developer-guide/dsl-api.html[Streams DSL] 
+provided by the Kafka Streams API is available for use in the business logic, too.
+
+An early version of the https://docs.confluent.io/current/streams/developer-guide/processor-api.html[Processor API] 
+support is available as well.
+
+As noted early-on, Kafka Streams support in Spring Cloud Stream strictly only available for use in the Processor model. 
+A model in which the messages read from an inbound topic, business processing can be applied, and the transformed messages 
+can be written to an outbound topic. It can also be used in Processor applications with a no-outbound destination.
+
+=== Streams DSL
+
+This application consumes data from a Kafka topic (e.g., `words`), computes word count for each unique word in a 5 seconds 
+time window, and the computed results are sent to a downstream topic (e.g., `counts`) for further processing.
+
+[source]
+----
+@SpringBootApplication
+@EnableBinding(KStreamProcessor.class)
+public class WordCountProcessorApplication {
+
+	@StreamListener("input")
+	@SendTo("output")
+	public KStream<?, WordCount> process(KStream<?, String> input) {
+		return input
+                .flatMapValues(value -> Arrays.asList(value.toLowerCase().split("\\W+")))
+                .groupBy((key, value) -> value)
+                .windowedBy(TimeWindows.of(5000))
+                .count(Materialized.as("WordCounts-multi"))
+                .toStream()
+                .map((key, value) -> new KeyValue<>(null, new WordCount(key.key(), value, new Date(key.window().start()), new Date(key.window().end()))));
+    }
+
+	public static void main(String[] args) {
+		SpringApplication.run(WordCountProcessorApplication.class, args);
+	}
+----
+
+Once built as a uber-jar (e.g., `wordcount-processor.jar`), you can run the above example like the following.
+
+[source]
+----
+java -jar wordcount-processor.jar  --spring.cloud.stream.bindings.input.destination=words --spring.cloud.stream.bindings.output.destination=counts
+----
+
+This application will consume messages from the Kafka topic `words` and the computed results are published to an output 
+topic `counts`.
+
+Spring Cloud Stream will ensure that the messages from both the incoming and outgoing topics are automatically bound as 
+KStream objects. As a developer, you can exclusively focus on the business aspects of the code, i.e. writing the logic 
+required in the processor. Setting up the Streams DSL specific configuration required by the Kafka Streams infrastructure 
+is automatically handled by the framework.
+
+== Configuration Options
+
+This section contains the configuration options used by the Kafka Streams binder.
+
+For common configuration options and properties pertaining to binder, refer to the <<binding-properties,core documentation>>.
+
+=== Kafka Streams Properties
+
+The following properties are available at the binder level and must be prefixed with `spring.cloud.stream.kafka.streams.binder.` 
+literal.
+
+configuration::
+  Map with a key/value pair containing properties pertaining to Apache Kafka Streams API.
+  This property must be prefixed with `spring.cloud.stream.kafka.streams.binder.`.
+ Following are some examples of using this property.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.binder.configuration.default.key.serde=org.apache.kafka.common.serialization.Serdes$StringSerde
+spring.cloud.stream.kafka.streams.binder.configuration.default.value.serde=org.apache.kafka.common.serialization.Serdes$StringSerde
+spring.cloud.stream.kafka.streams.binder.configuration.commit.interval.ms=1000
+----
+
+For more information about all the properties that may go into streams configuration, see StreamsConfig JavaDocs in 
+Apache Kafka Streams docs.
+
+brokers::
+ Broker URL

+ You can override the application id for an individual `StreamListener` method using the `group` property on the binding.
+ You have to ensure that you are using the same group name for all input bindings in the case of multiple inputs on the same methods.
++
+Default: `default`
+
+The following properties are _only_ available for Kafka Streams producers and must be prefixed with `spring.cloud.stream.kafka.streams.bindings.<binding name>.producer.` 
+literal.
+
+keySerde::
+  key serde to use
++
+Default: `none`.
+valueSerde::
+  value serde to use

+Default: `false`.
+
+The following properties are _only_ available for Kafka Streams consumers and must be prefixed with `spring.cloud.stream.kafka.streams.bindings.<binding name>.consumer.` 
+literal.
+
+keySerde::
+  key serde to use
++
+Default: `none`.

+  When this property is given, you can autowire a `TimeWindows` bean into the application.
+  The value is expressed in milliseconds.
++
+Default: `none`.
+spring.cloud.stream.kafka.streams.timeWindow.advanceBy::
+  Value is given in milliseconds.
++
+Default: `none`.
+
+== Multiple Input Bindings
+
+For use cases that requires multiple incoming KStream objects or a combination of KStream and KTable objects, the Kafka 
+Streams binder provides multiple bindings support. 
+
+Let's see it in action.
+
+=== Multiple Input Bindings as a Sink
+
+[source]
+----
+@EnableBinding(KStreamKTableBinding.class)
+.....
+.....
+@StreamListener
+public void process(@Input("inputStream") KStream<String, PlayEvent> playEvents,
+                    @Input("inputTable") KTable<Long, Song> songTable) {
+                    ....
+                    ....
+}
+
+interface KStreamKTableBinding {
+
+    @Input("inputStream")
+    KStream<?, ?> inputStream();
+
+    @Input("inputTable")
+    KTable<?, ?> inputTable();
+}
+
+----
+
+In the above example, the application is written as a sink, i.e. there are no output bindings and the application has to 
+decide concerning downstream processing. When you write applications in this style, you might want to send the information 
+downstream or store them in a state store (See below for Queryable State Stores).
+
+In the case of incoming KTable, if you want to materialize the computations to a state store, you have to express it 
+through the following property.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.inputTable.consumer.materializedAs: all-songs
+----
+
+=== Multiple Input Bindings as a Processor
+
+[source]
+----
+@EnableBinding(KStreamKTableBinding.class)
+....
+....
+
+@StreamListener
+@SendTo("output")
+public KStream<String, Long> process(@Input("input") KStream<String, Long> userClicksStream,
+                                     @Input("inputTable") KTable<String, String> userRegionsTable) {
+....
+....
+}
+
+interface KStreamKTableBinding extends KafkaStreamsProcessor {
+
+    @Input("inputX")
+    KTable<?, ?> inputTable();
+}
+
+----
+
+== Multiple Output Bindings (aka Branching)
+
+Kafka Streams allow outbound data to be split into multiple topics based on some predicates. The Kafka Streams binder provides 
+support for this feature without compromising the programming model exposed through `StreamListener` in the end user application.
+
+You can write the application in the usual way as demonstrated above in the word count example. However, when using the 
+branching feature, you are required to do a few things. First, you need to make sure that your return type is `KStream[]` 
+instead of a regular `KStream`. Second, you need to use the `SendTo` annotation containing the output bindings in the order 
+(see example below). For each of these output bindings, you need to configure destination, content-type etc., complying with 
+the standard Spring Cloud Stream expectations.
+
+Here is an example:
+
+[source]
+----
+@EnableBinding(KStreamProcessorWithBranches.class)
+@EnableAutoConfiguration
+public static class WordCountProcessorApplication {
+
+    @Autowired
+    private TimeWindows timeWindows;
+
+    @StreamListener("input")
+    @SendTo({"output1","output2","output3})
+    public KStream<?, WordCount>[] process(KStream<Object, String> input) {
+
+			Predicate<Object, WordCount> isEnglish = (k, v) -> v.word.equals("english");
+			Predicate<Object, WordCount> isFrench =  (k, v) -> v.word.equals("french");
+			Predicate<Object, WordCount> isSpanish = (k, v) -> v.word.equals("spanish");
+
+			return input
+					.flatMapValues(value -> Arrays.asList(value.toLowerCase().split("\\W+")))
+					.groupBy((key, value) -> value)
+					.windowedBy(timeWindows)
+					.count(Materialized.as("WordCounts-1"))
+					.toStream()
+					.map((key, value) -> new KeyValue<>(null, new WordCount(key.key(), value, new Date(key.window().start()), new Date(key.window().end()))))
+					.branch(isEnglish, isFrench, isSpanish);
+    }
+
+    interface KStreamProcessorWithBranches {
+
+    		@Input("input")
+    		KStream<?, ?> input();
+
+    		@Output("output1")
+    		KStream<?, ?> output1();
+
+    		@Output("output2")
+    		KStream<?, ?> output2();
+
+    		@Output("output3")
+    		KStream<?, ?> output3();
+    	}
+}
+----
+
+Properties:
+
+[source]

+spring.cloud.stream.bindings.output1.contentType: application/json
+spring.cloud.stream.bindings.output2.contentType: application/json
+spring.cloud.stream.bindings.output3.contentType: application/json

+----
+
+== Message Conversion
+
+Similar to message-channel based binder applications, the Kafka Streams binder adapts to the out-of-the-box content-type 
+conversions without any compromise.
+
+It is typical for Kafka Streams operations to know the type of SerDe’s used to transform the key and value correctly.
+Therefore, it may be more natural to rely on the SerDe facilities provided by the Apache Kafka Streams library itself at 
+the inbound and outbound conversions rather than using the content-type conversions offered by the framework.
+On the other hand, you might be already familiar with the content-type conversion patterns provided by the framework, and 
+that, you'd like to continue using for inbound and outbound conversions.
+
+Both the options are supported in the Kafka Streams binder implementation. 
+
+==== Outbound serialization
+
+If native encoding is disabled (which is the default), then the framework will convert the message using the contentType 
+set by the user (otherwise, the default `application/json` will be applied). It will ignore any SerDe set on the outbound 
+in this case for outbound serialization.
+
+Here is the property to set the contentType on the outbound.
+
+[source]
+----
+spring.cloud.stream.bindings.output.contentType: application/json
+----
+
+Here is the property to enable native encoding.
+
+[source]
+----
+spring.cloud.stream.bindings.output.nativeEncoding: true
+----
+
+If native encoding is enabled on the output binding (user has to enable it as above explicitly), then the framework will 
+skip any form of automatic message conversion on the outbound. In that case, it will switch to the Serde set by the user.
+The `valueSerde` property set on the actual output binding will be used. Here is an example.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.output.producer.valueSerde: org.apache.kafka.common.serialization.Serdes$StringSerde
+----
+If this property is not set, then it will use the "default" SerDe: `spring.cloud.stream.kafka.streams.binder.configuration.default.value.serde`.
+
+It is worth to mention that Kafka Streams binder does not serialize the keys on outbound - it simply relies on Kafka itself.
+Therefore, you either have to specify the `keySerde` property on the binding or it will default to the application-wide common 
+`keySerde`.
+
+Binding level key serde:
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.output.producer.keySerde
+----
+
+Common Key serde:
+
+[source]
+----
+spring.cloud.stream.kafka.streams.binder.configuration.default.key.serde
+----
+
+If branching is used, then you need to use multiple output bindings. For example,
+
+[source]
+----
+interface KStreamProcessorWithBranches {
+
+    		@Input("input")
+    		KStream<?, ?> input();
+
+    		@Output("output1")
+    		KStream<?, ?> output1();
+
+    		@Output("output2")
+    		KStream<?, ?> output2();
+
+    		@Output("output3")
+    		KStream<?, ?> output3();
+    	}
+----
+
+If `nativeEncoding` is set, then you can set different SerDe's on individual output bindings as below.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.output1.producer.valueSerde=IntegerSerde
+spring.cloud.stream.kafka.streams.bindings.output2.producer.valueSerde=StringSerde
+spring.cloud.stream.kafka.streams.bindings.output3.producer.valueSerde=JsonSerde
+----
+
+Then if you have `SendTo` like this, @SendTo({"output1", "output2", "output3"}), the `KStream[]` from the branches are 
+applied with proper SerDe objects as defined above. If you are not enabling `nativeEncoding`, you can then set different 
+contentType values on the output bindings as below. In that case, the framework will use the appropriate message converter 
+to convert the messages before sending to Kafka.
+
+[source]
+----
+spring.cloud.stream.bindings.output1.contentType: application/json
+spring.cloud.stream.bindings.output2.contentType: application/java-serialzied-object
+spring.cloud.stream.bindings.output3.contentType: application/octet-stream
+----
+
+==== Inbound Deserialization
+
+Similar rules apply to data deserialization on the inbound.
+
+If native decoding is disabled (which is the default), then the framework will convert the message using the contentType 
+set by the user (otherwise, the default `application/json` will be applied). It will ignore any SerDe set on the inbound 
+in this case for inbound deserialization.
+
+Here is the property to set the contentType on the inbound.
+
+[source]
+----
+spring.cloud.stream.bindings.input.contentType: application/json
+----
+
+Here is the property to enable native decoding.
+
+[source]
+----
+spring.cloud.stream.bindings.input.nativeDecoding: true
+----
+
+If native decoding is enabled on the input binding (user has to enable it as above explicitly), then the framework will 
+skip doing any message conversion on the inbound. In that case, it will switch to the SerDe set by the user. The `valueSerde` 
+property set on the actual output binding will be used. Here is an example.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.input.consumer.valueSerde: org.apache.kafka.common.serialization.Serdes$StringSerde
+----
+
+If this property is not set, it will use the default SerDe: `spring.cloud.stream.kafka.streams.binder.configuration.default.value.serde`.
+
+It is worth to mention that Kafka Streams binder does not deserialize the keys on inbound - it simply relies on Kafka itself.
+Therefore, you either have to specify the `keySerde` property on the binding or it will default to the application-wide common 
+`keySerde`.
+
+Binding level key serde:
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.input.consumer.keySerde
+----
+
+Common Key serde:
+
+[source]
+----
+spring.cloud.stream.kafka.streams.binder.configuration.default.key.serde
+----
+
+As in the case of KStream branching on the outbound, the benefit of setting value SerDe per binding is that if you have 
+multiple input bindings (multiple KStreams object) and they all require separate value SerDe's, then you can configure 
+them individually. If you use the common configuration approach, then this feature won't be applicable.
+
+== Error Handling
+
+Apache Kafka Streams provide the capability for natively handling exceptions from deserialization errors.
+For details on this support, please see https://cwiki.apache.org/confluence/display/KAFKA/KIP-161%3A+streams+deserialization+exception+handlers[this]
+Out of the box, Apache Kafka Streams provide two kinds of deserialization exception handlers - `logAndContinue` and `logAndFail`.
+As the name indicates, the former will log the error and continue processing the next records and the latter will log the 
+error and fail. `LogAndFail` is the default deserialization exception handler.
+
+=== Handling Deserialization Exceptions
+
+Kafka Streams binder supports a selection of exception handlers through the following properties.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.binder.serdeError: logAndContinue
+----
+
+In addition to the above two deserialization exception handlers, the binder also provides a third one for sending the erroneous 
+records (poison pills) to a DLQ topic. Here is how you enable this DLQ exception handler.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.binder.serdeError: sendToDlq
+----
+When the above property is set, all the deserialization error records are automatically sent to the DLQ topic.
+
+[source]
+----
+spring.cloud.stream.kafka.streams.bindings.input.consumer.dlqName: foo-dlq
+----
+
+If this is set, then the error records are sent to the topic `foo-dlq`. If this is not set, then it will create a DLQ 
+topic with the name `error.<input-topic-name>.<group-name>`.
+
+A couple of things to keep in mind when using the exception handling feature in Kafka Streams binder.
+
+* The property `spring.cloud.stream.kafka.streams.binder.serdeError` is applicable for the entire application. This implies 
+that if there are multiple `StreamListener` methods in the same application, this property is applied to all of them.
+* The exception handling for deserialization works consistently with native deserialization and framework provided message 
+conversion.
+
+=== Handling Non-Deserialization Exceptions
+
+For general error handling in Kafka Streams binder, it is up to the end user applications to handle application level errors.
+As a side effect of providing a DLQ for deserialization exception handlers, Kafka Streams binder provides a way to get 
+access to the DLQ sending bean directly from your application.
+Once you get access to that bean, you can programmatically send any exception records from your application to the DLQ.
+
+It continues to remain hard to robust error handling using the high-level DSL; Kafka Streams doesn't natively support error 
+handling yet. 
+
+However, when you use the low-level Processor API in your application, there are options to control this behavior. See 
+below.
+
+
+[source]
+----
+@Autowired
+private SendToDlqAndContinue dlqHandler;
+
+@StreamListener("input")
+@SendTo("output")
+public KStream<?, WordCount> process(KStream<Object, String> input) {
+
+    input.process(() -> new Processor() {
+    			ProcessorContext context;
+
+    			@Override
+    			public void init(ProcessorContext context) {
+    				this.context = context;
+    			}
+
+    			@Override
+    			public void process(Object o, Object o2) {
+
+    			    try {
+    			        .....
+    			        .....
+    			    }
+    			    catch(Exception e) {
+    			        //explicitly provide the kafka topic corresponding to the input binding as the first argument.
+                        //DLQ handler will correctly map to the dlq topic from the actual incoming destination.
+                        dlqHandler.sendToDlq("topic-name", (byte[]) o1, (byte[]) o2, context.partition());
+    			    }
+    			}
+
+    			.....
+    			.....
+    });
+}
+----
+
+== Interactive Queries
+
+As part of the public Kafka Streams binder API, we expose a class called `QueryableStoreRegistry`. You can access this 
+as a Spring bean in your application. An easy way to get access to this bean from your application is to "autowire" the bean 
+in your application.
+
+[source]
+----
+@Autowired
+private QueryableStoreRegistry queryableStoreRegistry;
+----
+
+Once you gain access to this bean, then you can query for the particular state-store that you are interested. See below.
+
+[source]
+----
+ReadOnlyKeyValueStore<Object, Object> keyValueStore =
+						queryableStoreRegistry.getQueryableStoreType("my-store", QueryableStoreTypes.keyValueStore());
+----
+
+== Accessing the underlying KafkaStreams object
+
+`StreamBuilderFactoryBean` from spring-kafka that is responsible for constructing the `KafkaStreams` object can be accessed programmatically.
+Each `StreamBuilderFactoryBean` is registered as `stream-builder` and appended with the `StreamListener` method name.
+If your `StreamListener` method is named as `process` for example, the stream builder bean is named as `stream-builder-process`.
+Since this is a factory bean, it should be accessed by prepending an ampersand (`&`) when accessing it programmatically.
+Following is an example and it assumes the `StreamListener` method is named as `process`
+
+[source]
+----
+StreamsBuilderFactoryBean streamsBuilderFactoryBean = context.getBean("&stream-builder-process", StreamsBuilderFactoryBean.class);
+			KafkaStreams kafkaStreams = streamsBuilderFactoryBean.getKafkaStreams();

+This guide describes the Apache Kafka implementation of the Spring Cloud Stream Binder.
+It contains information about its design, usage, and configuration options, as well as information on how the Stream Cloud Stream concepts map onto Apache Kafka specific constructs.
+In addition, this guide explains the Kafka Streams binding capabilities of Spring Cloud Stream.
+--
+
+== Usage
+
+To use Apache Kafka binder, you need to add `spring-cloud-stream-binder-kafka` as a dependency to your Spring Cloud Stream application, as shown in the following example for Maven:
+
+[source,xml]
+----
+<dependency>
+  <groupId>org.springframework.cloud</groupId>
+  <artifactId>spring-cloud-stream-binder-kafka</artifactId>
+</dependency>
+----
+
+Alternatively, you can also use the Spring Cloud Stream Kafka Starter, as shown inn the following example for Maven:
+
+[source,xml]
+----
+<dependency>
+  <groupId>org.springframework.cloud</groupId>
+  <artifactId>spring-cloud-starter-stream-kafka</artifactId>
+</dependency>
+----
+
+== Apache Kafka Binder Overview
+
+The following image shows a simplified diagram of how the Apache Kafka binder operates:
+
+.Kafka Binder
+image::images/kafka-binder.png[width=300,scaledwidth="50%"]
+
+The Apache Kafka Binder implementation maps each destination to an Apache Kafka topic.
+The consumer group maps directly to the same Apache Kafka concept.
+Partitioning also maps directly to Apache Kafka partitions as well.
+
+The binder currently uses the Apache Kafka `kafka-clients` 1.0.0 jar and is designed to be used with a broker of at least that version.
+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.
+
+== Configuration Options
+
+This section contains the configuration options used by the Apache Kafka binder.
+
+For common configuration options and properties pertaining to binder, see the <<binding-properties,core documentation>>.
+
+=== Kafka Binder Properties
+
+spring.cloud.stream.kafka.binder.brokers::
+A list of brokers to which the Kafka binder connects.
++
+Default: `localhost`.
+spring.cloud.stream.kafka.binder.defaultBrokerPort::
+`brokers` allows hosts specified with or without port information (for example, `host1,host2:port2`).
+This sets the default port when no port is configured in the broker list.
++
+Default: `9092`.
+spring.cloud.stream.kafka.binder.configuration::
+Key/Value map of client properties (both producers and consumer) passed to all clients created by the binder.
+Due to the fact that these properties are used by both producers and consumers, usage should be restricted to common properties -- for example, security settings.
++
+Default: Empty map.
+spring.cloud.stream.kafka.binder.headers::
+The list of custom headers that are transported by the binder.
+Only required when communicating with older applications (<= 1.3.x) with a `kafka-clients` version < 0.11.0.0. Newer versions support headers natively.
++
+Default: empty.
+spring.cloud.stream.kafka.binder.healthTimeout::
+The time to wait to get partition information, in seconds.
+Health reports as down if this timer expires.
++
+Default: 10.
+spring.cloud.stream.kafka.binder.requiredAcks::
+The number of required acks on the broker.
+See the Kafka documentation for the producer `acks` property.
++
+Default: `1`.
+spring.cloud.stream.kafka.binder.minPartitionCount::
+Effective only if `autoCreateTopics` or `autoAddPartitions` is set.
+The global minimum number of partitions that the binder configures on topics on which it produces or consumes data.
+It can be superseded by the `partitionCount` setting of the producer or by the value of `instanceCount * concurrency` settings of the producer (if either is larger).
++
+Default: `1`.
+spring.cloud.stream.kafka.binder.replicationFactor::
+The replication factor of auto-created topics if `autoCreateTopics` is active.
+Can be overridden on each binding.
++
+Default: `1`.
+spring.cloud.stream.kafka.binder.autoCreateTopics::
+If set to `true`, the binder creates new topics automatically.
+If set to `false`, the binder relies on the topics being already configured.
+In the latter case, if the topics do not exist, the binder fails to start.
++
+NOTE: This setting is independent of the `auto.topic.create.enable` setting of the broker and does not influence it.
+If the server is set to auto-create topics, they may be created as part of the metadata retrieval request, with default broker settings.
++
+Default: `true`.
+spring.cloud.stream.kafka.binder.autoAddPartitions::
+If set to `true`, the binder creates new partitions if required.
+If set to `false`, the binder relies on the partition size of the topic being already configured.
+If the partition count of the target topic is smaller than the expected value, the binder fails to start.
++
+Default: `false`.
+spring.cloud.stream.kafka.binder.transaction.transactionIdPrefix::
+Enables transactions in the binder. See `transaction.id` in the Kafka documentation and https://docs.spring.io/spring-kafka/reference/html/_reference.html#transactions[Transactions] in the `spring-kafka` documentation.
+When transactions are enabled, individual `producer` properties are ignored and all producers use the `spring.cloud.stream.kafka.binder.transaction.producer.*` properties.
++
+Default `null` (no transactions)
+spring.cloud.stream.kafka.binder.transaction.producer.*::
+Global producer properties for producers in a transactional binder.
+See `spring.cloud.stream.kafka.binder.transaction.transactionIdPrefix` and <<kafka-producer-properties>> and the general producer properties supported by all binders.
++
+Default: See individual producer properties.
+
+spring.cloud.stream.kafka.binder.headerMapperBeanName::
+The bean name of a `KafkaHeaderMapper` used for mapping `spring-messaging` headers to and from Kafka headers.
+Use this, for example, if you wish to customize the trusted packages in a `DefaultKafkaHeaderMapper` that uses JSON deserialization for the headers.
++
+Default: none.
+
+[[kafka-consumer-properties]]
+=== Kafka Consumer Properties
+
+The following properties are available for Kafka consumers only and
+must be prefixed with `spring.cloud.stream.kafka.bindings.<channelName>.consumer.`.
+
+admin.configuration::
+A `Map` of Kafka topic properties used when provisioning topics -- for example, `spring.cloud.stream.kafka.bindings.input.consumer.admin.configuration.message.format.version=0.9.0.0`
++
+Default: none.
+
+admin.replicas-assignment::
+A Map<Integer, List<Integer>> of replica assignments, with the key being the partition and the value being the assignments.
+Used when provisioning new topics.
+See the `NewTopic` Javadocs in the `kafka-clients` jar.
++
+Default: none.
+
+admin.replication-factor::
+The replication factor to use when provisioning topics. Overrides the binder-wide setting.
+Ignored if `replicas-assignments` is present.
++
+Default: none (the binder-wide default of 1 is used).
+
+autoRebalanceEnabled::
+When `true`, topic partitions is automatically rebalanced between the members of a consumer group.
+When `false`, each consumer is assigned a fixed set of partitions based on `spring.cloud.stream.instanceCount` and `spring.cloud.stream.instanceIndex`.
+This requires both the `spring.cloud.stream.instanceCount` and `spring.cloud.stream.instanceIndex` properties to be set appropriately on each launched instance.
+The value of the `spring.cloud.stream.instanceCount` property must typically be greater than 1 in this case.
++
+Default: `true`.
+ackEachRecord::
+When `autoCommitOffset` is `true`, this setting dictates whether to commit the offset after each record is processed.
+By default, offsets are committed after all records in the batch of records returned by `consumer.poll()` have been processed.
+The number of records returned by a poll can be controlled with the `max.poll.records` Kafka property, which is set through the consumer `configuration` property.
+Setting this to `true` may cause a degradation in performance, but doing so reduces the likelihood of redelivered records when a failure occurs.
+Also, see the binder `requiredAcks` property, which also affects the performance of committing offsets.
++
+Default: `false`.
+autoCommitOffset::
+Whether to autocommit offsets when a message has been processed.
+If set to `false`, a header with the key `kafka_acknowledgment` of the type `org.springframework.kafka.support.Acknowledgment` header is present in the inbound message.
+Applications may use this header for acknowledging messages.
+See the examples section for details.
+When this property is set to `false`, Kafka binder sets the ack mode to `org.springframework.kafka.listener.AbstractMessageListenerContainer.AckMode.MANUAL` and the application is responsible for acknowledging records.
+Also see `ackEachRecord`.
++
+Default: `true`.
+autoCommitOnError::
+Effective only if `autoCommitOffset` is set to `true`.
+If set to `false`, it suppresses auto-commits for messages that result in errors and commits only for successful messages. It allows a stream to automatically replay from the last successfully processed message, in case of persistent failures.
+If set to `true`, it always auto-commits (if auto-commit is enabled).
+If not set (the default), it effectively has the same value as `enableDlq`, auto-committing erroneous messages if they are sent to a DLQ and not committing them otherwise.
++
+Default: not set.
+resetOffsets::
+Whether to reset offsets on the consumer to the value provided by startOffset.
++
+Default: `false`.
+startOffset::
+The starting offset for new groups.
+Allowed values: `earliest` and `latest`.
+If the consumer group is set explicitly for the consumer 'binding' (through `spring.cloud.stream.bindings.<channelName>.group`), 'startOffset' is set to `earliest`. Otherwise, it is set to `latest` for the `anonymous` consumer group.
+Also see `resetOffsets` (earlier in this list).
++
+Default: null (equivalent to `earliest`).
+enableDlq::
+When set to true, it enables DLQ behavior for the consumer.
+By default, messages that result in errors are forwarded to a topic named `error.<destination>.<group>`.
+The DLQ topic name can be configurable by setting the `dlqName` property.
+This provides an alternative option to the more common Kafka replay scenario for the case when the number of errors is relatively small and replaying the entire original topic may be too cumbersome.
+See <<kafka-dlq-processing>> processing for more information.
+Starting with version 2.0, messages sent to the DLQ topic are enhanced with the following headers: `x-original-topic`, `x-exception-message`, and `x-exception-stacktrace` as `byte[]`.
++
+Default: `false`.
+configuration::
+Map with a key/value pair containing generic Kafka consumer properties.
++
+Default: Empty map.
+dlqName::
+The name of the DLQ topic to receive the error messages.
++
+Default: null (If not specified, messages that result in errors are forwarded to a topic named `error.<destination>.<group>`).
+dlqProducerProperties::
+Using this, DLQ-specific producer properties can be set.
+All the properties available through kafka producer properties can be set through this property.
++
+Default: Default Kafka producer properties.
+standardHeaders::
+Indicates which standard headers are populated by the inbound channel adapter.
+Allowed values: `none`, `id`, `timestamp`, or `both`.
+Useful if using native deserialization and the first component to receive a message needs an `id` (such as an aggregator that is configured to use a JDBC message store).
++
+Default: `none`
+converterBeanName::
+The name of a bean that implements `RecordMessageConverter`. Used in the inbound channel adapter to replace the default `MessagingMessageConverter`.
++
+Default: `null`
+idleEventInterval::
+The interval, in milliseconds, between events indicating that no messages have recently been received.
+Use an `ApplicationListener<ListenerContainerIdleEvent>` to receive these events.
+See <<pause-resume>> for a usage example.
++
+Default: `30000`
+
+[[kafka-producer-properties]]
+=== Kafka Producer Properties
+
+The following properties are available for Kafka producers only and
+must be prefixed with `spring.cloud.stream.kafka.bindings.<channelName>.producer.`.
+
+admin.configuration::
+A `Map` of Kafka topic properties used when provisioning new topics -- for example, `spring.cloud.stream.kafka.bindings.input.consumer.admin.configuration.message.format.version=0.9.0.0`
++
+Default: none.
+
+admin.replicas-assignment::
+A Map<Integer, List<Integer>> of replica assignments, with the key being the partition and the value being the assignments.
+Used when provisioning new topics.
+See `NewTopic` javadocs in the `kafka-clients` jar.
++
+Default: none.
+
+admin.replication-factor::
+The replication factor to use when provisioning new topics. Overrides the binder-wide setting.
+Ignored if `replicas-assignments` is present.
++
+Default: none (the binder-wide default of 1 is used).
+
+bufferSize::
+Upper limit, in bytes, of how much data the Kafka producer attempts to batch before sending.
++
+Default: `16384`.
+sync::
+Whether the producer is synchronous.
++
+Default: `false`.
+batchTimeout::
+How long the producer waits to allow more messages to accumulate in the same batch before sending the messages.
+(Normally, the producer does not wait at all and simply sends all the messages that accumulated while the previous send was in progress.) A non-zero value may increase throughput at the expense of latency.
++
+Default: `0`.
+messageKeyExpression::
+A SpEL expression evaluated against the outgoing message used to populate the key of the produced Kafka message -- for example, `headers['myKey']`.
+The payload cannot be used because, by the time this expression is evaluated, the payload is already in the form of a `byte[]`.
++
+Default: `none`.
+headerPatterns::
+A comma-delimited list of simple patterns to match Spring messaging headers to be mapped to the Kafka `Headers` in the `ProducerRecord`.
+Patterns can begin or end with the wildcard character (asterisk).
+Patterns can be negated by prefixing with `!`.
+Matching stops after the first match (positive or negative).
+For example `!ask,as*` will pass `ash` but not `ask`.
+`id` and `timestamp` are never mapped.
++
+Default: `*` (all headers - except the `id` and `timestamp`)
+configuration::
+Map with a key/value pair containing generic Kafka producer properties.
++
+Default: Empty map.
+
+NOTE: The Kafka binder uses the `partitionCount` setting of the producer as a hint to create a topic with the given partition count (in conjunction with the `minPartitionCount`, the maximum of the two being the value being used).
+Exercise caution when configuring both `minPartitionCount` for a binder and `partitionCount` for an application, as the larger value is used.
+If a topic already exists with a smaller partition count and `autoAddPartitions` is disabled (the default), the binder fails to start.
+If a topic already exists with a smaller partition count and `autoAddPartitions` is enabled, new partitions are added.
+If a topic already exists with a larger number of partitions than the maximum of (`minPartitionCount` or `partitionCount`), the existing partition count is used.
+
+=== Usage examples
+
+In this section, we show the use of the preceding properties for specific scenarios.
+
+==== Example: Setting `autoCommitOffset` to `false` and Relying on Manual Acking
+
+This example illustrates how one may manually acknowledge offsets in a consumer application.
+
+This example requires that `spring.cloud.stream.kafka.bindings.input.consumer.autoCommitOffset` be set to `false`.
+Use the corresponding input channel name for your example.
+
+[source]
+----
+@SpringBootApplication
+@EnableBinding(Sink.class)
+public class ManuallyAcknowdledgingConsumer {
+
+ public static void main(String[] args) {
+     SpringApplication.run(ManuallyAcknowdledgingConsumer.class, args);
+ }
+
+ @StreamListener(Sink.INPUT)
+ public void process(Message<?> message) {
+     Acknowledgment acknowledgment = message.getHeaders().get(KafkaHeaders.ACKNOWLEDGMENT, Acknowledgment.class);
+     if (acknowledgment != null) {
+         System.out.println("Acknowledgment provided");
+         acknowledgment.acknowledge();
+     }
+ }
+}
+----
+
+==== Example: Security Configuration
+
+Apache Kafka 0.9 supports secure connections between client and brokers.
+To take advantage of this feature, follow the guidelines in the http://kafka.apache.org/090/documentation.html#security_configclients[Apache Kafka Documentation] as well as the Kafka 0.9 http://docs.confluent.io/2.0.0/kafka/security.html[security guidelines from the Confluent documentation].
+Use the `spring.cloud.stream.kafka.binder.configuration` option to set security properties for all clients created by the binder.
+
+For example, to set `security.protocol` to `SASL_SSL`, set the following property:
+
+[source]
+----
+spring.cloud.stream.kafka.binder.configuration.security.protocol=SASL_SSL
+----
+
+All the other security properties can be set in a similar manner.
+
+When using Kerberos, follow the instructions in the http://kafka.apache.org/090/documentation.html#security_sasl_clientconfig[reference documentation] for creating and referencing the JAAS configuration.
+
+Spring Cloud Stream supports passing JAAS configuration information to the application by using a JAAS configuration file and using Spring Boot properties.
+
+===== Using JAAS Configuration Files
+
+The JAAS and (optionally) krb5 file locations can be set for Spring Cloud Stream applications by using system properties.
+The following example shows how to launch a Spring Cloud Stream application with SASL and Kerberos by using a JAAS configuration file:
+
+[source,bash]
+----
+ java -Djava.security.auth.login.config=/path.to/kafka_client_jaas.conf -jar log.jar \
+   --spring.cloud.stream.kafka.binder.brokers=secure.server:9092 \
+   --spring.cloud.stream.bindings.input.destination=stream.ticktock \
+   --spring.cloud.stream.kafka.binder.configuration.security.protocol=SASL_PLAINTEXT
+----
+
+===== Using Spring Boot Properties
+
+As an alternative to having a JAAS configuration file, Spring Cloud Stream provides a mechanism for setting up the JAAS configuration for Spring Cloud Stream applications by using Spring Boot properties.
+
+The following properties can be used to configure the login context of the Kafka client:
+
+spring.cloud.stream.kafka.binder.jaas.loginModule::
+The login module name. Not necessary to be set in normal cases.
++
+Default: `com.sun.security.auth.module.Krb5LoginModule`.
+spring.cloud.stream.kafka.binder.jaas.controlFlag::
+The control flag of the login module.
++
+Default: `required`.
+spring.cloud.stream.kafka.binder.jaas.options::
+Map with a key/value pair containing the login module options.
++
+Default: Empty map.
+
+The following example shows how to launch a Spring Cloud Stream application with SASL and Kerberos by using Spring Boot configuration properties:
+
+[source,bash]
+----
+ java --spring.cloud.stream.kafka.binder.brokers=secure.server:9092 \
+   --spring.cloud.stream.bindings.input.destination=stream.ticktock \
+   --spring.cloud.stream.kafka.binder.autoCreateTopics=false \
+   --spring.cloud.stream.kafka.binder.configuration.security.protocol=SASL_PLAINTEXT \
+   --spring.cloud.stream.kafka.binder.jaas.options.useKeyTab=true \
+   --spring.cloud.stream.kafka.binder.jaas.options.storeKey=true \
+   --spring.cloud.stream.kafka.binder.jaas.options.keyTab=/etc/security/keytabs/kafka_client.keytab \
+   --spring.cloud.stream.kafka.binder.jaas.options.principal=kafka-client-1@EXAMPLE.COM
+----
+
+The preceding example represents the equivalent of the following JAAS file:
+
+[source]
+----
+KafkaClient {
+    com.sun.security.auth.module.Krb5LoginModule required
+    useKeyTab=true
+    storeKey=true
+    keyTab="/etc/security/keytabs/kafka_client.keytab"
+    principal="kafka-client-1@EXAMPLE.COM";
+};
+----
+
+If the topics required already exist on the broker or will be created by an administrator, autocreation can be turned off and only client JAAS properties need to be sent.
+
+NOTE: Do not mix JAAS configuration files and Spring Boot properties in the same application.
+If the `-Djava.security.auth.login.config` system property is already present, Spring Cloud Stream ignores the Spring Boot properties.
+
+NOTE: Be careful when using the `autoCreateTopics` and `autoAddPartitions` with Kerberos.
+Usually, applications may use principals that do not have administrative rights in Kafka and Zookeeper.
+Consequently, relying on Spring Cloud Stream to create/modify topics may fail.
+In secure environments, we strongly recommend creating topics and managing ACLs administratively by using Kafka tooling.
+
+[[pause-resume]]
+==== 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.
+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());
+			}
+		};
+	}
+
+}
+----
+
+[[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 also be configured to send async producer send failures to an error channel.
+See <<spring-cloud-stream-overview-error-handling>> 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 producer exceptions (such as sending to a <<kafka-dlq-processing, Dead-Letter queue>>).
+You can consume these exceptions with your own Spring Integration flow.
+
+[[kafka-metrics]]
+== Kafka Metrics
+
+Kafka binder module exposes the following metrics:
+
+`spring.cloud.stream.binder.kafka.offset`: This metric indicates how many messages have not been yet consumed from a given binder's topic by a given consumer group.
+The metrics provided are based on the Mircometer metrics library. The metric contains the consumer group information, topic and the actual lag in committed offset from the latest offset on the topic.
+This metric is particularly useful for providing auto-scaling feedback to a PaaS platform.

+== Partitioning with the Kafka Binder
+
+Apache Kafka supports topic partitioning natively.
+
+Sometimes it is advantageous to send data to specific partitions -- for example, when you want to strictly order message processing (all messages for a particular customer should go to the same partition).
+
+The following example shows how to configure the producer and consumer side:
+
+[source, java]
+----
+@SpringBootApplication
+@EnableBinding(Source.class)
+public class KafkaPartitionProducerApplication {
+
+    private static final Random RANDOM = new Random(System.currentTimeMillis());
+
+    private static final String[] data = new String[] {
+            "foo1", "bar1", "qux1",
+            "foo2", "bar2", "qux2",
+            "foo3", "bar3", "qux3",
+            "foo4", "bar4", "qux4",
+            };
+
+    public static void main(String[] args) {
+        new SpringApplicationBuilder(KafkaPartitionProducerApplication.class)
+            .web(false)
+            .run(args);
+    }
+
+    @InboundChannelAdapter(channel = Source.OUTPUT, poller = @Poller(fixedRate = "5000"))
+    public Message<?> generate() {
+        String value = data[RANDOM.nextInt(data.length)];
+        System.out.println("Sending: " + value);
+        return MessageBuilder.withPayload(value)
+                .setHeader("partitionKey", value)
+                .build();
+    }
+
+}
+----
+
+.application.yml
+[source, yaml]
+----
+spring:
+  cloud:
+    stream:
+      bindings:
+        output:
+          destination: partitioned.topic
+          producer:
+            partitioned: true
+            partition-key-expression: headers['partitionKey']
+            partition-count: 12
+----
+
+IMPORTANT: The topic must be provisioned to have enough partitions to achieve the desired concurrency for all consumer groups.
+The above configuration supports up to 12 consumer instances (6 if their `concurrency` is 2, 4 if their concurrency is 3, and so on).
+It is generally best to "`over-provision`" the partitions to allow for future increases in consumers or concurrency.
+
+NOTE: The preceding configuration uses the default partitioning (`key.hashCode() % partitionCount`).
+This may or may not provide a suitably balanced algorithm, depending on the key values.
+You can override this default by using the `partitionSelectorExpression` or `partitionSelectorClass` properties.
+
+Since partitions are natively handled by Kafka, no special configuration is needed on the consumer side.
+Kafka allocates partitions across the instances.
+
+The following Spring Boot application listens to a Kafka stream and prints (to the console) the partition ID to which each message goes:
+
+[source, java]
+----
+@SpringBootApplication
+@EnableBinding(Sink.class)
+public class KafkaPartitionConsumerApplication {
+
+    public static void main(String[] args) {
+        new SpringApplicationBuilder(KafkaPartitionConsumerApplication.class)
+            .web(false)
+            .run(args);
+    }
+
+    @StreamListener(Sink.INPUT)
+    public void listen(@Payload String in, @Header(KafkaHeaders.RECEIVED_PARTITION_ID) int partition) {
+        System.out.println(in + " received from partition " + partition);
+    }
+
+}
+----

+      bindings:
+        input:
+          destination: partitioned.topic
+          group: myGroup
+----
+
+You can add instances as needed.
+Kafka rebalances the partition allocations.
+If the instance count (or `instance count * concurrency`) exceeds the number of partitions, some consumers are idle.

+ * common Serde set at the global level. If that fails, it falls back to byte[].
+ * If native decoding is disabled, then the binder will do the deserialization on value and ignore any Serde set for value
+ * and rely on the contentType provided. Keys are always deserialized at the broker.
+ *
+ * Same rules apply on the outbound. If native encoding is enabled, then value serialization is done at the broker using
+ * any binder level Serde for value, if not using common Serde, if not, then byte[].
+ * If native encoding is disabled, then the binder will do serialization using a contentType. Keys are always serialized
