+## gRPC 协议文档
+
+#### 1. protobuf
+
+在 `eventmesh-protocol-gprc` 模块有 Eventmesh gRPC 客户端的 protobuf 文件. the protobuf 文件路径是 `/src/main/proto/eventmesh-client.proto`.
+
+用gradle build 生成 gRPC 代码在 `/build/generated/source/proto/main`. 生成代码用于 `eventmesh-sdk-java` 模块.
+
+#### 2. gRPC 数据模型
+
+- 消息
+
+以下消息数据模型用于 `publish()`, `requestReply()` 和 `broadcast()` APIs.
+
+```
+message RequestHeader {
+    string env = 1;
+    string region = 2;
+    string idc = 3;
+    string ip = 4;
+    string pid = 5;
+    string sys = 6;
+    string username = 7;
+    string password = 8;
+    string language = 9;
+    string protocolType = 10;
+    string protocolVersion = 11;
+    string protocolDesc = 12;
+}
+
+message SimpleMessage {
+   RequestHeader header = 1;
+   string producerGroup = 2;
+   string topic = 3;
+   string content = 4;
+   string ttl = 5;
+   string uniqueId = 6;
+   string seqNum = 7;
+   string tag = 8;
+   map<string, string> properties = 9;
+}
+
+message BatchMessage {
+   RequestHeader header = 1;
+   string producerGroup = 2;
+   string topic = 3;
+
+   message MessageItem {
+      string content = 1;
+      string ttl = 2;
+      string uniqueId = 3;
+      string seqNum = 4;
+      string tag = 5;
+      map<string, string> properties = 6;
+   }
+
+   repeated MessageItem messageItem = 4;
+}
+
+message Response {
+   string respCode = 1;
+   string respMsg = 2;
+   string respTime = 3;
+}
+```
+
+- 订阅
+
+以下订阅数据模型用于 `subscribe()` 和 `unsubscribe()` APIs.
+
+```
+message Subscription {
+   RequestHeader header = 1;
+   string consumerGroup = 2;
+
+   message SubscriptionItem {
+      enum SubscriptionMode {
+         CLUSTERING = 0;
+         BROADCASTING = 1;
+      }
+
+      enum SubscriptionType {
+         ASYNC = 0;
+         SYNC = 1;
+      }
+
+      string topic = 1;
+      SubscriptionMode mode = 2;
+      SubscriptionType type = 3;
+   }
+
+   repeated SubscriptionItem subscriptionItems = 3;
+   string url = 4;
+}
+```
+
+- 心跳
+
+以下心跳数据模型用于 `heartbeat()` API.
+
+```
+message Heartbeat {
+  enum ClientType {
+     PUB = 0;
+     SUB = 1;
+  }
+
+  RequestHeader header = 1;
+  ClientType clientType = 2;
+  string producerGroup = 3;
+  string consumerGroup = 4;
+
+  message HeartbeatItem {
+     string topic = 1;
+     string url = 2;
+  }
+
+  repeated HeartbeatItem heartbeatItems = 5;
+}
+```
+
+#### 3. gRPC 服务接口
+
+- 事件生产端服务 APIs
+
+```
+service PublisherService {
+   # 异步事件生产
+   rpc publish(SimpleMessage) returns (Response);
+
+   # 同步事件生产
+   rpc requestReply(SimpleMessage) returns (Response);
+
+   # 批量事件生产
+   rpc batchPublish(BatchMessage) returns (Response);
+}
+```
+
+- 事件消费端服务 APIs
+
+```
+service ConsumerService {
+   # 所消费事件通过 HTTP Webhook推送事件
+   rpc subscribe(Subscription) returns (Response);
+
+   # 所消费事件通过 TCP stream推送事件
+   rpc subscribeStream(Subscription) returns (stream SimpleMessage);
+
+   rpc unsubscribe(Subscription) returns (Response);
+}
+```
+
+- 客户端心跳服务 API
+
+```
+service HeartbeatService {
+   rpc heartbeat(Heartbeat) returns (Response);
+}
+```
