+## 特性说明
+基于 memcached 实现的 RPC 协议。 `2.3.0` 以上版本支持。
+
+[Memcached](http://memcached.org/) 是一个高效的 KV 缓存服务器。
+
+## 使用场景
+## 使用方式
+#### 注册 memcached 服务的地址
+```java
+RegistryFactory registryFactory = ExtensionLoader.getExtensionLoader(RegistryFactory.class).getAdaptiveExtension();
+Registry registry = registryFactory.getRegistry(URL.valueOf("zookeeper://10.20.153.10:2181"));
+registry.register(URL.valueOf("memcached://10.20.153.11/com.foo.BarService?category=providers&dynamic=false&application=foo&group=member&loadbalance=consistenthash"));
+```
+
+#### 在客户端引用
+不需要感知 Memcached 的地址
+
+在客户端使用：
+
+```xml
+<dubbo:reference id="cache" interface="java.util.Map" group="member" />
+```
+
+或者点对点直连：
+
+```xml
+<dubbo:reference id="cache" interface="java.util.Map" url="memcached://10.20.153.10:11211" />
+```
+
+也可以使用自定义接口：
+```xml
+<dubbo:reference id="cache" interface="com.foo.CacheService" url="memcached://10.20.153.10:11211" />
+```
+
+其中 "p:xxx" 为 spring 的标准 p 标签
+```xml
+<dubbo:reference id="cache" interface="com.foo.CacheService" url="memcached://10.20.153.10:11211" p:set="putFoo" p:get="getFoo" p:delete="removeFoo" />
+```
+如果方法名和 memcached 的标准方法名不相同，则需要配置映射关系：
+
+方法名建议和 memcached 的标准方法名相同，即：get(key), set(key, value), delete(key)。
