+### [Enable sync message](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#producer-properties)
+
+To enable message sending in a synchronized way with Spring Cloud Stream 3.x, spring-cloud-azure-stream-binder-eventhubs supports the sync producer mode to get responses for sent messages. 
+Below classes are sample to use the sync mode:
+```
+ImperativeEventProducerController.java
+ManualProducerAndConsumerConfiguration.java   
+ReactiveEventProducerController.java
+```
+Try the sync mode with the "manual" profile after setting `spring.cloud.stream.eventhub.bindings.<binding-name>.producer.sync=true`. Users can send a POST request like following command:
+```
+$ ### Send messages through imperative.  
+$ curl -X POST http://localhost:8080/messages/imperative/staticalDestination?message=hello
+$ curl -X POST http://localhost:8080/messages/imperative/dynamicDestination?message=hello
+
+$ ### Send messages through reactive.
+$ curl -X POST http://localhost:8080/messages/reactive?message=hello
+```
+or when the app runs on App Service or VM
+```
+$ ### Send messages through imperative.
+$ curl -d -X POST https://[your-app-URL]/messages/imperative/staticalDestination?message=hello
+$ curl -d -X POST https://[your-app-URL]/messages/imperative/dynamicDestination?message=hello
+
+$ ### Send messages through reactive.
+$ curl -d -X POST https://[your-app-URL]/messages/reactive?message=hello
+```
+Verify in your app’s logs that a similar message was posted:
+```
+New message received: 'hello', partition key: 2002572479, sequence number: 4, offset: 768, enqueued time: 2021-06-03T01:47:36.859Z
+Message 'hello' successfully checkpointed
+```
+
+### [Using Batch Consuming](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#batch-consumer-support)
+
+To work with the batch-consumer mode, the property of spring.cloud.stream.bindings.<binding-name>.consumer.batch-mode should be set as true. When enabled, an org.springframework.messaging.Message of which the payload is a list of batched events will be received and passed to the consumer function.
+
+In this sample, users can try the batch-consuming mode by enable the "batch" profile and fill the "application-batch.yml". For more details about how to work in batch-consuming mode, please refer to the [reference doc](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#batch-consumer-support-2).
+
+### Set Event Hubs message headers
+
+Users can get all the supported EventHubs message headers [here](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#scs-eh-headers) to configure.
+
+### Resource Provision
+
+Event Hubs binder supports provisioning of event hub and consumer group, users could use [properties](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#resource-provision) to enable provisioning.
+
+### Partitioning Support
+
+A PartitionSupplier with user-provided partition information will be created to configure the partition information about the message to be sent, [Here](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#partitioning-support-2) is the process of obtaining different priorities of the partition ID and key.
+
+#### Partition key support
+The binder supports Event Hubs partitioning by allowing setting partition key and session id in the message header. This section introduces how to set partition key for messages.
+
+Spring Cloud Stream provides a partition key SpEL expression property spring.cloud.stream.bindings.<binding-name>.producer.partition-key-expression. For example, setting this properts as "'partitionKey-' + headers[<message-header-key>]" and add a header called <message-header-key>. Spring Cloud Stream will use the value for this header when evaluating the above expression to assign a partition key. Here is an example producer code:
+```java
+@Bean
+public Supplier<Message<String>> generate() {
+    return () -> {
+        String value = “random payload”;
+        return MessageBuilder.withPayload(value)
+            .setHeader("<message-header-key>", value.length() % 4)
+            .build();
+    };
+}
+```
+
+#### Session support
+The binder supports message sessions of Event Hubs. Session id of a message could be set via the message header.
+```java
+@Bean
+public Supplier<Message<String>> generate() {
+    return () -> {
+        String value = “random payload”;
+        return MessageBuilder.withPayload(value)
+            .setHeader(EventHubsMessageHeaders.SESSION_ID, "Customize session id")
+            .build();
+    };
+}
+```
+### Error Channel
+
+Event Hubs binder supports consumer error channel, producer error channel and global default error channel, click [here](https://microsoft.github.io/spring-cloud-azure/4.0.0-beta.4/4.0.0-beta.4/reference/html/index.html#error-channels) to see more information.
