+By default, consumer in `Key_Shared` subscription will be assigned a fixed
hash range of key automatically. If you want to specify the hash ranges of a
consumer, you can using the key shared policy:
+
+```java
+Consumer consumer = client.newConsumer()
+ .topic("my-topic")
+ .subscriptionName("my-subscription")
+ .subscriptionType(SubscriptionType.Key_Shared)
+
.keySharedPolicy(KeySharedPolicy.sticky().ranges(Range.of(0, 10)))
+ .subscribe()
+```
+
+The consumer with specific key hash ranges also can be called a sticky
consumer. Available key hash range is [0, 65535] , consumers of the
subscription must cover the whole key hash range and no overlap .
Review comment:
```suggestion
The consumer with a specific key hash range can be called a **sticky
consumer**. The available key hash range is [0, 65535]. Consumers of a
subscription must cover the whole key hash range and can not overlap.
