+# EventMesh 当前架构问题与统一化必要性
+
+> 文档目的：基于 `qqeasonchen/eventmesh` 的 `develop` 分支代码，梳理当前 EventMesh 架构（含 `eventmesh-runtime` + `eventmesh-runtime-v2` 双运行时）存在的系统性缺陷，解释为什么需要统一运行时重构。
+>
+> 对应蓝图：[EventMesh 统一运行时架构蓝图 v2.0](./eventmesh-unified-runtime-architecture-review.md)
+>
+> Review 范围：`develop` 分支的 `eventmesh-runtime`、`eventmesh-runtime-v2`、`eventmesh-connector-*`、`eventmesh-protocol-plugin` 相关实现。
+
+---
+
+## 结论先行
+
+**当前 EventMesh 有 6 个架构级问题，核心矛盾是「双运行时 + 协议割裂 + Connector 安全旁路」。统一运行时不是可选优化——是解决这些问题的唯一路径。**
+
+本次基于 `develop` 分支代码继续 review 后，结论进一步加重：
+
+1. `develop` 上已经出现 A2A 相关代码，但主进程 `EventMeshServer` 没有把 A2A 服务接入生命周期，说明「继续外挂新能力」已经开始制造半集成状态。
+2. `eventmesh-runtime-v2` 的 `MeshRuntime` 仍是空实现，v2 名义上的三种 Runtime 并未真正闭环。
+3. `ConnectorRuntime` / `FunctionRuntime` 复制了大段 Runtime 骨架，但都没有接入 v1 的 ACL/Auth/RateLimit/Trace 体系。
+4. `ConnectorRuntime.start()` 的 Source/Sink 线程 `finally` 中存在 `System.exit(-1)`，属于架构分裂诱发的高危稳定性问题：运行时内部线程异常会直接杀掉整个 JVM。
+
+| # | 问题 | 严重程度 | develop 代码现状 | 影响 |
+|---|------|----------|-------------------|------|
+| 1 | 双运行时进程隔离开销 | 🔴 高 | `eventmesh-runtime` 与 `eventmesh-runtime-v2` 仍是两套启动、两套生命周期 | 运维复杂、资源浪费、部署耦合 |
+| 2 | 每协议独立 Processor 链，逻辑大量重复 | 🔴 高 | HTTP/TCP/gRPC 仍各自维护 Processor 链 | 改一个安全策略要改多处入口 |
+| 3 | Connector 数据流绕过安全策略 | 🔴 致命 | `ConnectorRuntime` 仍通过 `BlockingQueue<ConnectRecord>` 串 Source/Sink | ACL/AuthFilter/RateLimit 对 Connector 无效 |
+| 4 | 没有统一 Pipeline 抽象 | 🟡 中 | `FilterEngine` 只是 Function pattern 过滤，不是统一安全责任链 | 不同入口的消息处理路径不一致 |
+| 5 | 代码量膨胀，Bug 修复面扩散 | 🟡 中 | `ConnectorRuntime` 与 `FunctionRuntime` 重复初始化 gRPC、Storage、队列、线程池 | 改一处，查三处；容易产生生命周期 Bug |
+| 6 | A2A Agent 协议缺乏原生 Pipeline 承载 | 🟡 中 | A2A 代码已在 `runtime/a2a`，但未挂入 `EventMeshServer` 主生命周期 | Agent 通信被迫外挂，安全/观测/路由难统一 |
+

+

+                    Admin Server / Storage / Meta
+```
+
+**两个独立 JVM 进程，两套启动脚本，两套配置，两个类加载器空间。**
+
+本次 review 确认：`develop` 并没有把 v2 能力收回 v1 主进程，也没有把 v1 的协议网关能力下沉成可复用 Pipeline。相反，A2A 又被追加进 `eventmesh-runtime/src/main/java/org/apache/eventmesh/runtime/a2a/`，进一步证明当前架构仍在按「新增目录 + 独立服务」方式演进。
+
+### 1.2 为什么会有两个 Runtime？
+
+历史演进导致的分裂：
+
+| 版本 | 定位 | 核心职责 | 当前问题 |
+|------|------|----------|----------|
+| **runtime-v1** | 消息协议网关 | TCP/HTTP/gRPC 消息接入、路由、分发、Admin | 协议 Processor 逻辑重复，缺统一 Pipeline |
+| **runtime-v2** | 连接器 + 函数运行时 | Connector(Source/Sink)、Function、Mesh 编排 | 独立进程、独立队列、独立存储连接，绕过 v1 安全链 |
+| **A2A 目录** | Agent 通信入口 | Agent Card、Task、Gateway、SSE | 代码存在，但未接入主进程生命周期和统一 Pipeline |
+
+v2 是在 v1 基础上「加塞」出来的——没有重构 v1，而是新建模块走独立进程。A2A 又是在 v1 中追加目录实现，而不是复用统一协议栈。这直接导致问题 1-6。
+
+---
+
+## 二、问题 1：双运行时进程隔离开销
+
+### 2.1 运维复杂度
+
+```
+生产环境部署需要同时启动：
+  start.sh      → EventMeshStartup         (v1, 主进程)
+  start-v2.sh   → RuntimeInstanceStarter   (v2, 独立进程)
+```
+
+| 运维负担 | 表现 |
+|----------|------|
+| **两套启停脚本** | `start.sh`/`stop.sh` 和 `start-v2.sh`/`stop-v2.sh`，分别写 pid 文件 |
+| **两套日志目录** | 各自输出到 `logs/`，排查问题时要在两份日志间跳转 |
+| **两套 JVM 配置** | v1 和 v2 各占用堆内存，合计浪费 2 个 JVM 的 metaspace + direct memory 开销 |
+| **健康检查碎片化** | 需要监控两个进程的存活，任一挂掉都影响 Connector 服务 |
+| **版本不一致风险** | v1 和 v2 可能从不同构建产物部署，接口不兼容难以发现 |
+
+### 2.2 资源浪费
+
+```java
+// v1: EventMeshServer 拥有完整的 ACL、MetaStorage、Trace、Metrics 体系
+this.acl = Acl.getInstance(...);
+this.metaStorage = MetaStorage.getInstance(...);
+trace = Trace.getInstance(...);
+this.storageResource = StorageResource.getInstance(...);
+
+// v2: ConnectorRuntime 也独立初始化 gRPC channel、Storage Plugin、Offset 存储
+channel = ManagedChannelBuilder.forTarget(adminServerAddr).build();
+producer = StoragePluginFactory.getMeshMQProducer(...);
+consumer = StoragePluginFactory.getMeshMQPushConsumer(...);
+offsetManagementService.initialize(...);
+```
+
+**同一个物理节点上，对 Kafka/RocketMQ 的连接数翻倍，gRPC channel 翻倍，存储插件初始化翻倍——完全不需要。**
+
+本次 review 还确认 `FunctionRuntime` 也复制了类似初始化骨架：独立 gRPC stub、独立 Source/Sink 线程、独立队列。这不是「Connector 特例」，而是 v2 Runtime 抽象本身的重复。
+
+### 2.3 进程间通信开销
+
+v2 的 ConnectorRuntime 通过 gRPC 与 Admin Server 通信：
+
+```java
+// ConnectorRuntime: 通过 gRPC fetch job 配置
+Payload response = adminServiceBlockingStub.invoke(request);
+
+// 健康检查心跳也是 gRPC
+healthService = new HealthService(adminServiceStub, adminServiceBlockingStub, ...);
+```
+
+如果在同一 JVM 内，这应该是本地方法调用，而非序列化 → 网络 → 反序列化往返。
+
+### 2.4 新发现：v2 内部线程可直接杀死整个 JVM
+
+`ConnectorRuntime.start()` 的 Source/Sink 执行逻辑在 `finally` 中调用 `System.exit(-1)`：
+
+```java
+sinkService.execute(() -> {
+    try {
+        startSinkConnector();
+    } finally {
+        System.exit(-1);
+    }
+});
+
+sourceService.execute(() -> {
+    try {
+        startSourceConnector();
+    } finally {
+        System.exit(-1);
+    }
+});
+```
+
+这类代码在双运行时架构下尤其危险：
+
+- Source/Sink 任一线程异常退出，会直接终止 v2 JVM；
+- 进程级退出绕过 Runtime 生命周期管理，无法让上层做优雅降级、隔离重启或状态上报；
+- 如果未来把 v2 合并进 v1，这段逻辑会直接把整个 EventMesh 主进程杀掉。
+
+这不是单纯 Bug，而是缺少统一 Runtime 生命周期管理导致的典型后果。
+
+---
+
+## 三、问题 2：每协议独立 Processor 链，逻辑大量重复
+
+### 3.1 三层协议，三层 Processor
+
+v1 对每种传输协议都实现了一套完整的 Processor 链：
+
+```
+TCP 协议
+├── HelloProcessor, GoodbyeProcessor
+├── SubscribeProcessor, UnSubscribeProcessor
+├── MessageTransferProcessor, MessageAckProcessor
+├── HeartBeatProcessor, ListenProcessor, RecommendProcessor
+
+HTTP 协议
+├── SendAsyncMessageProcessor, SendSyncMessageProcessor
+├── BatchSendMessageProcessor, BatchSendMessageV2Processor
+├── SendAsyncEventProcessor, SendAsyncRemoteEventProcessor
+├── ReplyMessageProcessor, HeartBeatProcessor
+├── SubscribeProcessor, UnSubscribeProcessor
+├── CreateTopicProcessor, DeleteTopicProcessor
+├── AdminMetricsProcessor, AdminShutdownProcessor
+├── LocalSubscribeEventProcessor, RemoteSubscribeEventProcessor
+├── LocalUnSubscribeEventProcessor, RemoteUnSubscribeEventProcessor
+
+gRPC 协议
+├── RequestCloudEventProcessor, PublishCloudEventsProcessor
+├── BatchPublishCloudEventProcessor
+├── AbstractPublishCloudEventProcessor, AbstractPublishBatchCloudEventProcessor
+├── SubscribeProcessor, SubscribeStreamProcessor, UnsubscribeProcessor
+├── HeartbeatProcessor, ReplyMessageProcessor
+```
+
+**review `develop` 的 HTTP processor 目录可见，Send/Batch/Reply/Subscribe/Admin/Topic 等入口仍然拆成大量独立 Processor 类。**
+
+### 3.2 每个 Processor 里的重复逻辑
+
+以 `SendAsyncMessageProcessor` (HTTP) 为例，其 `processRequest` 方法包含：
+
+```java
+// ① 协议解析 (Protocol Adaptor)
+CloudEvent event = httpCommandProtocolAdaptor.toCloudEvent(request);
+
+// ② ACL 检查
+this.acl.doAclCheckInHttpSend(remoteAddr, user, pass, subsystem, topic, requestCode);
+
+// ③ TTL 注入
+event = CloudEventBuilder.from(event).withExtension(TTL, ttl).build();
+
+// ④ 发送到 Storage
+this.eventMeshHTTPServer.getProducer().send(event, callback);
+```
+
+TCP 协议的 `MessageTransferProcessor` 和 gRPC 协议的 `RequestCloudEventProcessor` 中，步骤 ②③④ 的逻辑高度相似，区别主要在步骤 ① 的协议解析。
+
+**当需要修改一个安全策略（比如增加新的 Auth plugin）时，需要同步审查多个协议入口。** 这正是统一 Pipeline 应该解决的问题：协议层只负责 `TransportRequest → CloudEvent/Message`，安全、转换、路由、发送不应该散落在每个 Processor 中。
+
+### 3.3 V1 vs V2：两套 Send 逻辑
+
+```java
+// v1 SendAsyncMessageProcessor:
+eventMeshHTTPServer.getProducer().send(event, callback);
+
+// v2 ConnectorRuntime:
+queue.put(record);              // Source 直接往 BlockingQueue 塞
+sinkConnector.put(recordList);  // Sink 从 queue 取，直接写外部系统
+```
+
+v2 的 Connector 不仅不走 ACL，连消息发送机制都完全不同——它用 `BlockingQueue` 代替 v1 的 Producer/Consumer 路径。两套逻辑互不感知。
+
+---
+
+## 四、问题 3：Connector 数据流绕过安全策略（致命）
+
+### 4.1 数据流对比
+
+```
+HTTP/TCP/gRPC 消息流：
+  客户端 → Endpoint → Adaptor.toCloudEvent() → ACL/Auth/限流/校验 → Producer.send() → Storage
+
+Connector 消息流：
+  Source.poll() → BlockingQueue.put(record) → Sink.put(recordList) → 外部系统
+                                   ↑
+                         完全绕过了以下所有安全层：
+                           · ACL 权限检查
+                           · AuthFilter 认证
+                           · RateLimit 限流
+                           · SizeLimit 大小限制
+                           · ProtocolFilter 合规校验
+                           · Trace 链路追踪
+```
+
+### 4.2 代码证据
+
+```java
+// ConnectorRuntime.java
+private final BlockingQueue<ConnectRecord> queue;  // LinkedBlockingQueue(1000)
+
+// Source 直接往队列塞，不经过任何 Filter
+queue.put(record);
+
+// Sink 从队列取，直接写外部系统
+sinkConnector.put(recordList);  // 没有 ACL/Auth/RateLimit
+```
+
+这条链路的问题不是「缺少某个 if 判断」，而是压根没有进入 v1 的协议处理链，也没有进入任何统一 Pipeline。
+
+### 4.3 安全后果
+
+| 攻击向量 | v1 防护 | v2 Connector 防护 |
+|----------|---------|-------------------|
+| 未授权 Topic 写入 | ACL 检查拦截 | ❌ 无统一防护 |
+| 流量洪峰 | RateLimit 限流 | ❌ 无统一防护，仅有本地队列容量 |
+| 恶意大数据包 | SizeLimit 拦截 | ❌ 无统一防护 |
+| 认证伪造 | AuthFilter 校验 | ❌ 无统一防护 |
+| 操作审计 | Trace 链路追踪 | ❌ 无统一追踪 |
+
+**一个恶意或失控的 Source Connector 插件可以持续向 Sink 灌数据，EventMesh 主协议链完全感知不到。**
+
+### 4.4 背压也没有统一语义
+
+`ConnectorRuntime` 使用 `LinkedBlockingQueue(1000)` 作为 Source/Sink 中间缓冲。这个队列只能提供本地阻塞，不能提供统一背压语义：
+
+- 上游 Source 不知道是下游 Sink 慢、外部系统慢，还是 EventMesh 限流；
+- 队列满时只是阻塞 Source 线程，没有 Metrics/Trace/告警上下文；
+- 不同 Connector 的队列容量、错误恢复、重试策略很难和主 Runtime 统一。
+
+因此 Connector 旁路不仅是安全问题，也是稳定性和可观测性问题。
+
+---
+
+## 五、问题 4：没有统一 Pipeline 抽象
+
+### 5.1 develop 当前状态
+
+`develop` 分支的 `eventmesh-runtime/boot/EventMeshServer.java` 主生命周期只初始化 HTTP/TCP/gRPC/Admin 等 Bootstrap：
+
+```java
+BOOTSTRAP_LIST.add(new EventMeshHttpBootstrap(this));
+BOOTSTRAP_LIST.add(new EventMeshTcpBootstrap(this));
+BOOTSTRAP_LIST.add(new EventMeshGrpcBootstrap(this));
+BOOTSTRAP_LIST.add(new EventMeshAdminServer(this));
+```
+
+本次 review 未看到它挂载以下统一处理组件：
+
+- `IngressProcessor`
+- `EgressProcessor`
+- `EventMeshConnectorBootstrap`
+- `A2APublishSubscribeService`
+- 安全 Filter 责任链
+
+这说明 `develop` 的主进程仍是协议 Bootstrap 聚合器，不是统一 Runtime。
+
+### 5.2 develop 上的 FilterEngine 不是安全 Pipeline
+
+`develop` 中确实存在 `FilterEngine`，但它的职责是 Function 内容过滤：
+
+```java
+private Map<String, Pattern> filterPatternMap;
+
+// 定期从 MetaStorage 拉取 function 配置，并编译 pattern
+Pattern pattern = Pattern.compile(function.getPattern());
+filterPatternMap.put(function.getId(), pattern);
+```
+
+它不是统一 Pipeline 的 Filter 责任链，原因很明确：
+
+| 能力 | FilterEngine 当前实现 | 统一 Pipeline 应有实现 |
+|------|----------------------|------------------------|
+| Auth | ❌ 无 | ✅ AuthFilter |
+| ACL | ❌ 无 | ✅ AclFilter |
+| RateLimit | ❌ 无 | ✅ RateLimitFilter |
+| SizeLimit | ❌ 无 | ✅ SizeLimitFilter |
+| Protocol Compliance | ❌ 无 | ✅ ProtocolFilter |
+| Trace/Metrics | ❌ 非 Pipeline 级 | ✅ 每个 Stage 可观测 |
+| 多 Filter 链式组合 | ❌ 单一 `filterPatternMap` | ✅ Ordered Chain / Responsibility Chain |
+
+当前 `FilterEngine` 更准确地说是 **Function-level pattern filter registry**，不是 **Security + Function Pipeline**。
+
+### 5.3 没有 Pipeline 的后果
+
+```
+每个协议的消息处理变成了 N 份独立实现：
+
+HTTP Send  → ①httpAdaptor → ②doACL → ③producer.send
+TCP  Send  → ①tcpAdaptor  → ②doACL → ③producer.send
+gRPC Send  → ①grpcAdaptor → ②doACL → ③producer.send
+Connector  → ①source.poll → ②queue.put → ③sink.put
+A2A        → ①gateway     → ②task/sse  → ③publish/subscribe?
+
+少了统一 Pipeline 抽象 → 步骤②③无法复用 → 安全策略修改 = 批量改文件
+```
+
+统一 Pipeline 的目标应该是：所有入口统一进入 `IngressPipeline`，所有出口统一进入 `EgressPipeline`；协议适配只做格式转换，不能承载安全和路由主逻辑。
+
+---
+
+## 六、问题 5：代码规模膨胀与维护负担
+
+### 6.1 模块职责重叠
+
+```java
+// runtime-v1: EventMeshServer 管理 Bootstrap 列表
+BOOTSTRAP_LIST.add(new EventMeshHttpBootstrap(this));
+BOOTSTRAP_LIST.add(new EventMeshTcpBootstrap(this));
+BOOTSTRAP_LIST.add(new EventMeshGrpcBootstrap(this));
+
+// runtime-v2: RuntimeInstance 管理 Runtime 列表
+RuntimeFactory factory = new ConnectorRuntimeFactory();
+RuntimeFactory factory = new FunctionRuntimeFactory();
+RuntimeFactory factory = new MeshRuntimeFactory();
+```
+
+两个 Runtime 各自发明了不同的「组件生命周期管理」机制（Bootstrap vs RuntimeFactory），但做的事情很接近。
+
+### 6.2 ConnectorRuntime 与 FunctionRuntime 高度重复
+
+本次 review 进一步确认：`ConnectorRuntime` 与 `FunctionRuntime` 的结构高度相似，重复点包括：
+
+- 读取 Runtime 配置；
+- 创建 AdminService gRPC stub；
+- 初始化 Source/Sink Connector；
+- 使用本地 `LinkedBlockingQueue` 串接 Source/Sink；
+- 初始化 Storage producer/consumer；
+- 初始化 Offset 管理；
+- 启动 Source/Sink 线程池；
+- 独立做健康检查和 stop 逻辑。
+
+这说明 v2 并没有抽出稳定的 Runtime Template，而是在不同 Runtime 类型中复制一套骨架。复制越多，生命周期 bug 越容易扩散。
+
+### 6.3 MeshRuntime 名义存在，实际为空
+
+`eventmesh-runtime-v2/src/main/java/org/apache/eventmesh/runtime/mesh/MeshRuntime.java` 在 `develop` 上基本是空实现：
+
+```java
+public class MeshRuntime implements Runtime {
+    @Override
+    public void init(RuntimeInstance runtimeInstance) throws Exception {
+    }
+
+    @Override
+    public void start() throws Exception {
+    }
+
+    @Override
+    public void stop() throws Exception {
+    }
+}
+```
+
+这意味着 `RuntimeFactory` 暴露了 `MeshRuntimeFactory`，但真正的 Mesh 编排能力没有落地。架构上看，这是一个「概念已占位、实现未闭环」的信号：继续保留独立 v2 只会让 API/配置/文档先膨胀，实际能力却难以和主链路整合。
+
+### 6.4 Bug 修复面扩散
+
+unified-runtime-pipeline 分支的历史提交记录已经暴露了这个问题：
+
+```
+d419b28f8 Fix Source connector filtered-event NPE
+34229034a Revert "[ISSUE] Fix all review issues in unified-runtime-pipeline"
+03963a188 [ISSUE] Fix all review issues in unified-runtime-pipeline
+```
+
+修复一个 NPE 或 review issue 时，需要跨 v1、v2、connector 三个模块同时修改——因为相同逻辑分散在三处。
+
+本次 `develop` review 新发现的 `System.exit(-1)` 也属于同类问题：Runtime 生命周期控制分散在 v2 内部线程中，没有统一 supervision model。
+
+---
+
+## 七、问题 6：A2A Agent 协议缺乏原生 Pipeline 承载
+
+### 7.1 develop 当前 A2A 代码位置
+
+`develop` 分支已经存在 A2A 相关代码目录：
+
+```
+eventmesh-runtime/src/main/java/org/apache/eventmesh/runtime/a2a/
+├── A2ACardHttpHandler.java
+├── A2AGatewayHttpHandler.java
+├── A2AGatewayServer.java
+├── A2AGatewayService.java
+├── A2APublishSubscribeService.java
+├── InMemoryA2AMessageTransport.java
+└── TaskRegistry.java
+```
+
+这与早期判断「A2A 只在重构分支」相比有变化：**A2A 代码已经进入 develop，但仍是半集成状态。**
+
+### 7.2 A2A 未接入 EventMeshServer 主生命周期
+
+本次 review `EventMeshServer.java` 后，未看到主生命周期中初始化或启动：
+
+- `A2AGatewayServer`
+- `A2AGatewayService`
+- `A2APublishSubscribeService`
+
+`BOOTSTRAP_LIST` 仍主要是 HTTP/TCP/gRPC/Admin。也就是说，A2A 目录存在，但没有成为 EventMesh 主 Runtime 的一等入口。
+
+### 7.3 为什么需要统一 Pipeline 承载 A2A
+
+A2A 作为 Agent 通信的业务协议，其流量本质上和普通消息流量一样——需要经过 Pipeline：
+
+```
+Agent A → A2A REST API → IngressPipeline → Storage/Router → EgressPipeline → Agent B
+
+如果没有 Pipeline：
+  · A2A Gateway 需要重复实现 ACL/Auth/RateLimit
+  · Trace 无法追踪跨 Agent 调用链
+  · 无法对 A2A 流量做统一 Transformer/Filter
+  · Agent Task 状态与消息投递状态难以统一观测
+```
+
+A2A 的 Agent Card / Task / SSE 可以复用 HTTP Endpoint 的传输层，但业务语义（Task 状态机、Agent 发现、Streaming）需要独立的编程模型层实现——这正是五层协议栈的设计目标。
+
+### 7.4 半集成状态的风险
+
+当前状态最危险的地方不是「没有 A2A」，而是「A2A 代码已经存在，但未进入统一主链路」。这会带来三类风险：
+
+| 风险 | 表现 |
+|------|------|
+| 安全重复 | A2A Gateway 如果独立暴露 HTTP API，需要单独补 Auth/ACL/RateLimit |
+| 可观测性断裂 | Task/SSE/Message 的 trace id、metrics tag 与普通消息链路不一致 |
+| 演进分叉 | 后续 A2A 修复会在 `runtime/a2a` 内自成体系，进一步扩大统一成本 |
+
+---
+
+## 八、问题根因分析
+
+### 8.1 技术债务来源
+
+```
+项目初期
+  ↓
+runtime-v1 建成（TCP/HTTP/gRPC 网关）
+  ↓
+需求：支持 Connector 数据集成
+  ↓
+  决策：新建 runtime-v2 模块（避免改 v1）
+        ↓
+        runtime-v2 独立进程 + 独立代码
+        ↓
+        共享 Admin Server（gRPC 通信）
+  ↓
+需求：支持 Function/Mesh Runtime
+  ↓
+  决策：继续在 v2 中扩展 RuntimeFactory
+        ↓
+        ConnectorRuntime / FunctionRuntime 重复骨架
+        ↓
+        MeshRuntime 占位但未实现
+  ↓
+需求：支持 Agent 通信 (A2A)
+  ↓
+  决策：在 runtime-v1 中追加 A2A Gateway 目录
+        ↓
+        但没有重构 v1 的协议处理链
+        ↓
+        也没有合并 v2 的功能
+  ↓
+现状：协议网关 + Connector + Function + A2A 各自一套代码路径
+```
+
+### 8.2 为什么「暂时不改」会越来越糟
+
+| 时间点 | 问题规模 | 修复代价 |
+|--------|---------|----------|
+| 只有 v1 时 | 协议 Processor 重复 | 中等 |
+| v2 加入后 | Runtime 与安全链分裂 | 较高 |
+| Function/Mesh 加入后 | v2 内部 Runtime 骨架重复 | 高 |
+| A2A 加入后 | 新业务协议半集成 | 更高 |
+| 再叠加新协议 (MQTT/WebSocket/更多 Agent 协议) | N × M 倍扩散 | 不可接受 |
+
+**每增加一个新入口，都需要在所有 Processor 或 Gateway 中重复 ACL/Auth/RateLimit/Transformer/Router 逻辑。统一 Pipeline 就是把 N×M 的复杂度降回 N+M。**
+
+---
+
+## 九、统一化的核心收益
+
+### 9.1 对照表
+
+| 维度 | 当前 | 统一后 |
+|------|------|--------|
+| JVM 进程数 | 2 (`eventmesh-runtime` + `eventmesh-runtime-v2`) + Admin 相关通信 | 1 个主 Runtime，必要能力组件化 |
+| 安全策略维护 | 每个 Processor/Gateway/Connector 各自实现或缺失 | Pipeline 中 Auth/ACL/RateLimit/SizeLimit/ProtocolFilter 统一处理 |
+| Connector 是否过安全链 | ❌ `BlockingQueue` 旁路 | ✅ Source/Sink 都经 Ingress/Egress Pipeline |
+| 新增协议入口 | 写全套 Processor + ACL + Transformer | 只需实现 Adaptor + Endpoint，主逻辑复用 Pipeline |

+
+### 9.2 建议的统一目标
+
+统一运行时不只是「把 v2 代码搬进 v1」，而是要建立清晰的五层协议栈：
+
+```
+Programming Model Layer
+  - Messaging API
+  - Connector Source/Sink
+  - Function
+  - A2A Agent Task/Card/SSE
+
+Data Format Layer
+  - CloudEvents
+  - OpenMessaging
+  - A2A Message/Task Event
+
+Transport Layer
+  - HTTP
+  - TCP
+  - gRPC
+  - Connector Adapter
+  - A2A REST/SSE
+
+Pipeline Layer
+  - AuthFilter
+  - AclFilter
+  - RateLimitFilter
+  - SizeLimitFilter
+  - ProtocolFilter
+  - FunctionFilter / Transformer / Router
+  - Trace / Metrics Stage
+
+Storage Layer
+  - Kafka / RocketMQ / Pulsar / InMemory
+```
+
+### 9.3 一句话总结
+
+```
+当前架构的问题不是「某个模块写得差」——是「多个运行时和多个入口各搞一套，
+互相不认，本该统一的安全策略被 Connector BlockingQueue 旁路掉了，
+新增 A2A 又继续走外挂目录模式」。
+
+统一 Pipeline 就是强制所有入口走同一条 Auth → ACL → RateLimit → Transform → Route → Storage 链，
+同时把 v1/v2 两个 JVM 进程合并成一个可监督、可观测、可扩展的 Runtime。
+```

+# EventMesh 统一运行时架构设计
+
+> 分支：`refactor/unified-runtime-pipeline`
+> 目标：以单一 EventMesh Runtime 替代 runtime-v1/runtime-v2 双运行时，承载全部消息处理 + Connector 管理 + A2A 协议
+
+---
+
+## 结论先行
+
+**统一运行时是 EventMesh 从"协议网关"演进为"A2A 消息总线"的正确路径。**
+
+它按照五层协议栈架构组织：编程模型层（OpenMessaging API / A2A Protocol）→ 数据格式层（CloudEvents Envelope）→ 传输协议层（TCP/HTTP/gRPC）→ 处理引擎层（Pipeline Filter → Transformer → Router）→ 存储层（Kafka/RocketMQ/Pulsar）。所有协议入口和 Connector 数据流都经过统一的 Pipeline 处理链，消除 runtime-v1 和 runtime-v2 之间的代码重复和进程隔离开销，同时保留并增强原 Runtime V2 的管理面能力（Admin Server 通信、动态 Job 调度、Offset 管理、指标上报、数据校验）。
+
+一次性完成迁移，不留兼容尾巴，最终形态只有 **一个 Runtime，一套 Pipeline，一个部署模型**。

+| **Layer 5 · 编程模型** | OpenMessaging API + A2A Protocol | 客户端编程接口 | 开发者用什么 API 收发消息 |

+- **OpenMessaging** 定义的是 API 契约：`Producer`/`Consumer`/`PushConsumer`/`Subscribe`。它是开发者写代码时调用的接口——"我调用 `producer.send()` 就能发消息"。OpenMessaging 与传输协议无关——同一套 API 可以跑在 TCP 上，也可以跑在 HTTP 上。
+- **CloudEvents** 定义的是数据格式：所有消息（不管来自 OpenMessaging 还是 A2A）在进入 Pipeline 之前都会被编码为 CloudEvents 信封。Pipeline 只认 CloudEvents——这也是为什么 Filter/Transformer/Router 能对 TCP/HTTP/gRPC/A2A/Connector 统一处理。
+- **A2A** 和 OpenMessaging 处于同一层：都是编程模型。区别在于 OpenMessaging 面向传统消息 Pub/Sub（"发一条消息到 Topic"），A2A 面向 Agent 间通信（"创建一个 Task 让下游 Agent 执行"）。两者都基于 CloudEvents 编码，都走 Pipeline。
+
+**A2A 和 OpenMessaging 的平级关系：**
+
+| 维度 | OpenMessaging | A2A |
+|------|--------------|-----|
+| 层级 | Layer 5 (编程模型) | Layer 5 (编程模型) |
+| 语义 | Pub/Sub 消息 | Agent 任务 |
+| 客户端 API | `Producer.send()` / `Consumer.subscribe()` | `AgentCard.discover()` / `Task.create()` |
+| 传输绑定 | TCP / HTTP / gRPC 均可 | 仅 HTTP (REST + SSE) |
+| 内部编码 | CloudEvents | CloudEvents |
+| 典型场景 | 微服务间异步消息 | AI Agent 间协作调用 |
+
+> **核心原则：OpenMessaging 和 A2A 是"客户端怎么说"，CloudEvents 是"数据怎么传"，TCP/HTTP/gRPC 是"字节怎么走"。三者正交，不互斥。**
+
+### 协议对象全枚举

+
+#### 逐对象说明
+
+| 对象 | 全类名 | 层级 | 角色 | 字段/说明 |
+|------|--------|------|------|----------|
+| **OpenMessaging Message** | `io.openmessaging.api.Message` | Layer 5 | 客户端编程模型 | 标准消息 API（topic/body/properties/key/tag），用户写代码时直接操作 |
+| **EventMeshMessage** | `o.a.e.common.EventMeshMessage` | Layer 5 | 简化编程模型 | `bizSeqNo` + `uniqueId` + `topic` + `content`(String) + `prop`(Map)。比 OpenMessaging 更轻量，TCP/HTTP/gRPC SDK 通用 |
+| **A2A Message** | JSON (MCP/Agent Card 序列化) | Layer 5 | Agent 通信语义 | Agent Card / Task / SSE Event。客户端不直接操作 Java 类，而是通过 JSON 序列化 |
+| **Package** | `o.a.e.common.protocol.tcp.Package` | Layer 4 | TCP 传输帧 | `Header`(命令码 + 路由信息) + `body`(Object)。TCP 二进制线的协议帧格式——**不是消息格式，是帧格式** |
+| **HttpEventWrapper** | `o.a.e.common.protocol.http.HttpEventWrapper` | Layer 4 | HTTP 传输载体 | `headerMap` + `sysHeaderMap` + `body`(byte[]) + `requestURI`。HTTP 请求的通用载体 |
+| **HttpCommand** | `o.a.e.common.protocol.http.HttpCommand` | Layer 4 | HTTP 传输载体(旧) | `opaque` + `requestCode` + `Header` + `Body`。标记 `@Deprecated`，逐步被 `HttpEventWrapper` 替代 |
+| **CloudEvent (gRPC)** | `o.a.e.common.protocol.grpc.cloudevents.CloudEvent` | Layer 4 | gRPC 传输 PB | Protobuf 定义的 CloudEvents 1.0 规范消息。注意：这是 **Protobuf 序列化格式**，不是 `io.cloudevents.CloudEvent` |
+| **EventMeshCloudEventWrapper** | `o.a.e.common.protocol.grpc.common.EventMeshCloudEventWrapper` | Layer 4 | gRPC 传输载体 | 包裹一个 gRPC CloudEvent，实现 `ProtocolTransportObject` |
+| **BatchEventMeshCloudEventWrapper** | `o.a.e.common.protocol.grpc.common.BatchEventMeshCloudEventWrapper` | Layer 4 | gRPC 批量载体 | 包裹一批 gRPC CloudEvent |
+| **ProtocolTransportObject** | `o.a.e.common.protocol.ProtocolTransportObject` | Layer 4 | 传输对象基接口 | 标记接口（extends `Serializable`），所有传输对象实现它。**Pipeline 不直接处理这类对象**——由 ProtocolAdaptor 先转换为 CloudEvents |
+| **io.cloudevents.CloudEvent** | `io.cloudevents.CloudEvent` | Layer 3.5 | 统一内部格式 | CloudEvents 1.0 规范的标准 Java 接口。**Pipeline 的唯一数据格式**。所有 ProtocolAdaptor 的输出统一为这个格式 |
+
+#### ProtocolAdaptor —— 协议转换枢纽
+
+**所有 `ProtocolTransportObject` 必须先通过 `ProtocolAdaptor` 才能进入 Pipeline：**
+
+```java
+// SPI 接口，关键方法签名
+public interface ProtocolAdaptor<T extends ProtocolTransportObject> {
+
+    // 入口：将任意传输对象转换为 CloudEvent
+    CloudEvent toCloudEvent(T protocol) throws ProtocolHandleException;
+
+    // 批量入口
+    List<CloudEvent> toBatchCloudEvent(T protocol) throws ProtocolHandleException;
+
+    // 出口：将 CloudEvent 转换回传输对象（下发给消费者）
+    ProtocolTransportObject fromCloudEvent(CloudEvent cloudEvent) throws ProtocolHandleException;
+
+    // 协议标识
+    String getProtocolType();   // "cloudevents" / "http" / "meshmessage" / "openmessage" / "a2a"
+}
+```
+
+**当前注册的 Adaptor 与协议类型映射：**
+
+| Adaptor | `getProtocolType()` | 输入 → 输出 | 用途 |
+|---------|---------------------|-------------|------|
+| `CloudEventsProtocolAdaptor` | `cloudevents` | gRPC CloudEvent PB → io.cloudevents.CloudEvent | gRPC CloudEvents 入口 |
+| `HttpProtocolAdaptor` | `http` | `HttpEventWrapper` → io.cloudevents.CloudEvent | HTTP 入口 |
+| `MeshMessageProtocolAdaptor` | `meshmessage` | TCP `Package`(body=EventMeshMessage) → io.cloudevents.CloudEvent | TCP EventMeshMessage 入口 |
+| `OpenMessageProtocolAdaptor` | `openmessage` | `io.openmessaging.api.Message` → io.cloudevents.CloudEvent | OpenMessaging 客户端入口 |
+| `EnhancedA2AProtocolAdaptor` | `a2a` | A2A JSON → io.cloudevents.CloudEvent（内部委托 CloudEvents + HTTP Adaptor） | A2A Agent 通信入口 |

+
+> **关键结论：**
+> 1. **ProtocolTransportObject 是"信封的外壳"**（TCP 帧 / HTTP 请求体 / gRPC PB），不包含业务语义
+> 2. **io.cloudevents.CloudEvent 是"信封的内胆"**（统一的事件数据格式），包含业务语义
+> 3. **ProtocolAdaptor 是"开信封的机器"**——拆开各种协议外壳，露出统一的 CloudEvents 内胆给 Pipeline
+> 4. **Pipeline 永远不碰 ProtocolTransportObject**——它只处理 `io.cloudevents.CloudEvent`
+
+---
+
+## 二、核心组件设计
+
+### 2.1 Pipeline 核心 —— IngressProcessor / EgressProcessor
+
+**统一消息处理链，所有协议入口和出口共用同一套 Filter → Transformer → Router 管线。**
+
+```
+消息流入 (任何协议)
+    │
+    ▼
+IngressProcessor
+    ├── Filter Engine   → 鉴权、限流、协议校验、规则匹配
+    ├── Transformer Engine → 协议转换、字段映射、消息丰富化
+    └── Router Engine    → 按 Topic/Header 路由到目标 MQ Topic
+    │
+    ▼
+  Storage Plugin (Kafka / RocketMQ / Pulsar)
+    │
+    ▼
+EgressProcessor
+    ├── Filter Engine   → 消费者过滤、订阅匹配
+    ├── Transformer Engine → 消息格式转换、脱敏
+    └── Router Engine    → 推送到目标协议处理器 (TCP/HTTP/gRPC/Connector Sink)
+```
+
+**Pipeline Context 协议（最终形态）：**
+
+```java
+interface PipelineStage {
+    PipelineResult process(PipelineContext ctx);
+}
+
+class PipelineResult {
+    enum Action { CONTINUE, DROP, RETRY, DLQ, FAIL }
+
+    Action action;
+    CloudEvent event;
+    Throwable cause;
+    Map<String, String> metadata;
+}
+```
+
+- `CONTINUE`：正常流转到下一阶段
+- `DROP`：静默丢弃（替代当前 `null` 返回语义）
+- `RETRY`：重试（携带重试次数等上下文）
+- `DLQ`：路由到死信队列
+- `FAIL`：抛出异常/告警
+
+当前 Pipeline 保留 `null` 兼容层，`DROP` 语义等价于返回 `null`，长期以 `PipelineResult.Action` 为规范接口。
+
+**已接入的协议路径：**
+
+| 协议 | 处理器 | 接入方式 | 层级 |
+|------|--------|----------|------|
+| TCP Producer | `PublishCloudEventsProcessor` | `IngressProcessor.process()` | 传输层 |
+| TCP Consumer | `ClientGroupWrapper` | `EgressProcessor.process()` | 传输层 |
+| HTTP Send | `SendAsyncMessageProcessor` / `SendSyncMessageProcessor` | `IngressProcessor.process()` | 传输层 |
+| HTTP Batch | `BatchSendMessageProcessor` / `BatchSendMessageV2Processor` | `IngressProcessor.process()` | 传输层 |
+| gRPC Publish | `RequestCloudEventProcessor` | `IngressProcessor.process()` | 传输层 |
+| gRPC Batch | `BatchPublishCloudEventProcessor` | `IngressProcessor.process()` | 传输层 |
+| A2A | A2A Gateway → HTTP Endpoint | `IngressProcessor.process()` | 业务协议 (基于 HTTP) |
+| Source Connector | `EventMeshConnectorBootstrap` | `IngressProcessor.process()` | 数据源 |
+| Sink Connector | `EventMeshConnectorBootstrap` | `EgressProcessor.process()` | 数据目标 |
+
+> **A2A 是业务协议，不是传输协议。** A2A 的 REST API 和 SSE 都走 HTTP Endpoint 进入 Pipeline，A2A Gateway 负责解析 Agent Card / Task 语义，将结构化消息交给 Pipeline 处理。TCP/HTTP/gRPC 是传输层，A2A 在其之上。
+
+---
+
+### 2.2 Connector Runtime Service
+
+**在统一 Runtime 内管理多个 Connector 实例，支持动态注册/启停。**
+
+```java
+public class ConnectorRuntimeService {
+    // 注册 Connector（动态）
+    void registerConnector(ConnectorConfig config) throws Exception;
+
+    // 卸载 Connector（动态）
+    void unregisterConnector(String connectorName) throws Exception;
+
+    // 启停
+    void startConnector(String connectorName) throws Exception;
+    void stopConnector(String connectorName) throws Exception;
+
+    // 状态查询
+    List<ConnectorStatus> getConnectorStatuses();
+    ConnectorStatus getConnectorStatus(String connectorName);
+}
+```
+
+| 能力 | 实现方式 |
+|------|----------|
+| 多 Connector 并行 | 默认独立线程池（可切共享池） |
+| 动态注册/卸载 | 通过 HTTP/gRPC 管理 API |
+| 故障隔离 | 独立 ClassLoader + try-catch 边界，单 Connector 异常不影响其他 |
+| 配置热更新 | 通过 Admin Server 下发，ConnectorRuntimeService 热重载 |
+| 插件发现 | SPI 机制 + 配置文件声明 |
+
+**线程池策略设计：**
+
+> 为什么默认独立线程池而非共享池？
+
+| 方案 | 优点 | 缺点 | 适用 |
+|------|------|------|------|
+| **DEDICATED**（默认） | 故障隔离绝对；背压 per-Connector；出问题秒定位到哪个 Connector | 多 Connector 时空闲线程浪费 | 生产多租户 |
+| **SHARED** | 资源利用率高 | 一个慢 Connector 占满池 → 全部堵死；head-of-line blocking | 低负载/同质 Connector |
+| VIRTUAL（Java 21+） | 极轻量，百万并发 | EventMesh 需兼容 Java 8/11；`synchronized` 会 pin carrier；不解决故障隔离 | 未来可选 |
+
+核心取舍：Connector 是插件代码，质量不可控——一个 Source 的 `poll()` 阻塞在共享池里会把整个 Runtime 的消息处理全卡死。
+
+**提供两种线程池模式，通过配置切换：**
+
+```properties
+# DEDICATED: 每个 Connector 独立线程池（生产推荐）
+# SHARED: 所有 Connector 共享一个线程池（轻量场景）
+eventmesh.connector.thread.pool.mode=DEDICATED
+
+# DEDICATED 模式下每个 Connector 的线程数（默认 2，非重型 Connector 1-2 足够）
+eventmesh.connector.thread.pool.size=2
+
+# SHARED 模式下的全局线程数
+eventmesh.connector.thread.pool.shared.size=8
+```
+
+**ConnectorConfig 数据模型：**
+
+```java
+class ConnectorConfig {
+    String connectorName;       // rocketmq-source / http-sink
+    ConnectorType type;         // SOURCE / SINK
+    String pluginClass;         // 全限定类名
+    Map<String, String> props;  // Connector 配置
+    ThreadPoolMode poolMode;    // DEDICATED / SHARED（未设置走全局默认）
+    int threadPoolSize;         // 线程池大小（DEDICATED 默认 2）
+    int maxRetry;               // 最大重试次数
+}
+
+enum ThreadPoolMode { DEDICATED, SHARED }
+```
+
+**Connector 注册上限：**
+
+当前 Connector 注册无界（`ConcurrentHashMap` 直接 put），这在生产环境下是危险的——100 个 Connector 可能耗尽 JVM 内存/线程/FD。增加可配置上限，reach 上限时 `registerConnector()` 抛出 `ConnectorLimitExceededException`。
+
+```java
+public class ConnectorRuntimeService {
+    private final int maxConnectors;  // 上限，-1 = 无限制
+
+    void registerConnector(ConnectorConfig config) throws ConnectorLimitExceededException {
+        if (maxConnectors > 0 && connectors.size() >= maxConnectors) {
+            throw new ConnectorLimitExceededException(
+                "Max connectors reached: " + maxConnectors);
+        }
+        // ...
+    }
+}
+```
+
+```properties
+# -1 = 无限制，0 = 仅允许配置文件声明的静态 Connector
+eventmesh.connector.max.count=16
+```
+
+**上限计算规则（预估）：**
+
+| 资源 | 每 Connector 消耗 | 16 个 Connector 总消耗 |
+|------|------------------|----------------------|
+| 线程 (DEDICATED) | 2 | 32 threads — 4-core safe |
+| 内存 | ~5MB (ClassLoader + buffer) | 80MB — 2GB heap 只占 4% |
+| 网络连接 | ≥1 (Source 侧) | 16+ conns |
+
+默认值 `16` 覆盖常见生产场景（4 source + 4 sink + 8 function-connector），保守且安全。可通过 Admin Server 动态调大。
+
+```properties
+# 运行时动态调整
+eventmesh.connector.max.count=-1    # 关闭上限（开发环境）
+eventmesh.connector.max.count=0     # 仅允许配置文件静态声明
+eventmesh.connector.max.count=32    # 生产扩容
+```
+
+#### Connector 完整数据流
+
+**一个 Connector Job 是 Source+Sink 配对。理想路径是 Source 拉取 → Pipeline → Storage 持久化 → Pipeline → Sink 写入目标——全程经过统一安全链。**
+
+```

+
+关键设计点：
+  ① 所有 Connector 数据强制经过 Pipeline → 安全策略对 Connector 与协议消息一视同仁
+  ② Storage 持久化 → 消息不丢，Offset 可回溯，Source 和 Sink 彻底解耦
+  ③ Ingress/Egress 对称 → Source 走 Ingress, Sink 走 Egress, 同一套 Filter/Transformer/Router
+```
+
+```
+旧架构对比（当前 v2 ConnectorRuntime 的实际行为）：
+ 
+ Source.poll()
+      │
+      ▼  ❌ 无 Ingress Pipeline
+ BlockingQueue<ConnectRecord>  (纯内存, 容量 1000)
+      │
+      ▼  ❌ 无 Storage 持久化
+ Sink.put()
+      │
+      ▼  ❌ 无 Egress Pipeline
+  外部系统
+
+三个致命问题：
+  · 无 Pipeline → ACL/Auth/RateLimit 对 Connector 完全失效
+  · 无 Storage → 进程挂了 BlockingQueue 里的数据全丢，Offset 无法恢复
+  · Source/Sink 紧耦合 → 换 Sink 要改 Source 配置，无法独立伸缩
+```
+
+> **设计原则：Pipeline 是唯一数据面，所有入口（TCP/HTTP/gRPC/A2A/Connector Source）共享同一条 Filter → Transformer → Router 链。**
+
+```
+

+
+### 2.3 Admin Client —— 运行时管理面通信
+
+**内置 Admin Server 客户端，统一 Runtime 通过 gRPC BiStream 双向流与管理面上报状态、接收指令。**
+
+```
+Runtime (每个实例)  ──gRPC BiStream──>  Admin Server
+    │                                       │
+    ├── Heartbeat (5s 间隔)                 ├── Runtime 健康状态汇总
+    ├── Monitor Report (30s 间隔)           ├── 指标存储与查询
+    ├── Verify Report (按需)                ├── 数据校验汇总
+    ├── Status Update (状态变更时)           ├── Runtime 状态看板
+    └── Offset Sync (60s 间隔)              ├── 集群级 Offset 管理
+                                            └── Job 调度指令下发
+```
+
+**AdminClient 能力矩阵：**
+
+| 组件 | 来源 | 职责 |
+|------|------|------|
+| **HealthService** | 迁移自 runtime-v2 | 心跳上报，携带 runtimeAddress + status + activeJobCount |
+| **MonitorService** | 迁移自 runtime-v2 | Pipeline 处理延迟、Connector 吞吐量、TPS/QPS 指标采集上报 |
+| **VerifyService** | 迁移自 runtime-v2 | 在 Ingress/Egress 处理链中埋点，支持端到端数据校验 |
+| **StatusService** | 迁移自 runtime-v2 | Runtime 级别状态管理（STARTING/RUNNING/DEGRADED/STOPPING） |
+| **AdminCommandHandler** | 新增 | 接收 Admin Server 下发的 Job 调度指令 |
+
+**配置项：**
+
+```properties
+# Admin Server 通信
+eventmesh.admin.server.enabled=true
+eventmesh.admin.server.address=localhost:50051
+eventmesh.admin.server.heartbeat.interval.seconds=5
+eventmesh.admin.server.monitor.report.interval.seconds=30
+
+# 降级模式（Admin Server 不可用时 Runtime 可独立运行）
+eventmesh.admin.server.required=false
+```
+
+- 当 `required=false` 且 Admin Server 不可达时，Runtime 降级为单机模式，不影响消息处理核心路径
+- 当 `required=true` 时，Admin Server 不可达则 Runtime 启动失败
+
+---
+
+### 2.4 Offset 管理 —— Exactly-Once 保障
+
+**双写策略：本地 RocksDB（进程重启不丢） + 远程 Admin Server（集群级恢复）。**
+
+```
+Connector Source 消费消息
+    │
+    ├──► 本地 Offset Store (RocksDB)
+    │    Key: {connectorName}:{topic}:{partition}
+    │    Value: {position, timestamp}
+    │    写入时机: 每条消息处理完成后
+    │
+    └──► 远程 Offset Manager (Admin Server)
+         同步时机: 每 60s 批量上报
+         恢复时机: Runtime 启动时从 Admin Server 拉取
+```
+
+**OffsetStore 接口：**
+
+```java
+public interface OffsetStore {
+    void save(String connectorName, String topic, int partition, String position);
+    String load(String connectorName, String topic, int partition);
+    Map<String, String> loadAll(String connectorName);
+    void flush();
+    void close();
+}
+```
+
+恢复优先级：本地 RocksDB > 远程 Admin Server > 配置默认值（latest/earliest）
+
+---
+
+### 2.5 动态 Job 管理
+
+**通过 HTTP REST API 和 gRPC 指令两种方式管理 Connector Job 生命周期。**
+
+**HTTP 管理 API：**
+
+```
+POST   /admin/jobs                  # 创建 Job
+GET    /admin/jobs                  # 列出所有 Job
+GET    /admin/jobs/{jobId}          # 获取 Job 详情
+PUT    /admin/jobs/{jobId}/start    # 启动 Job
+PUT    /admin/jobs/{jobId}/stop     # 停止 Job
+DELETE /admin/jobs/{jobId}          # 删除 Job
+GET    /admin/jobs/{jobId}/status   # Job 状态
+GET    /admin/health                # Runtime 健康检查
+GET    /admin/metrics               # Runtime 指标
+```
+
+**JobInfo 数据模型（对齐 Admin Server 的 EventMeshJobInfo）：**
+
+```java
+class JobInfo {
+    String jobId;
+    String jobName;
+    ConnectorType connectorType;   // SOURCE / SINK
+    String connectorName;
+    String config;                 // JSON 格式 Connector 配置
+    JobState state;                // CREATED / RUNNING / STOPPED / FAILED
+    long createTime;
+    long updateTime;
+    String errorMessage;           // 失败原因
+}

+
+### 2.6 A2A Protocol Layer
+
+**EventMesh 作为 Agent 消息总线的业务协议实现。A2A 处于协议栈的 Layer 5 (编程模型层)，与 OpenMessaging 平级——都面向开发者定义"怎么用"，只是一个面向 Agent 通信、一个面向传统消息 Pub/Sub。A2A 基于 HTTP 传输（REST API + SSE），复用 HTTP Endpoint 进入 Pipeline，而非另起独立的传输层端口。内部消息编码为 CloudEvents，与其他协议消息共享 Pipeline 处理链。**
+
+```
+Agent Client ──HTTP──→ [HTTP Endpoint] ──→ Pipeline
+                      ↑
+              A2A Gateway 在此层解析
+              · Agent Card 注册/发现
+              · Task 创建/状态追踪
+              · SSE 流式推送
+```
+
+| 组件 | 职责 | 传输 |
+|------|------|------|
+| **Agent Card Registry** | Agent 注册、发现、心跳管理 | `GET/POST /.well-known/agent-card` |
+| **A2A REST Gateway** | RESTful API 入口，接收 Agent 间调用 | `POST /a2a/tasks` |
+| **SSE Streaming** | Server-Sent Events 流式响应 | `GET /a2a/tasks/{id}/stream` |
+| **Task Lifecycle** | 异步 Task 创建、状态跟踪、结果回调 | `GET/POST/DELETE /a2a/tasks/{id}` |
+| **Java SDK** | Java Agent 接入 SDK，封装 A2A 协议 | HTTP Client → EventMesh HTTP Endpoint |
+
+A2A 消息流经 Pipeline 处理链，与其他传输层消息共用 Filter/Transformer/Router 管线，确保所有消息遵循统一的安全策略和路由规则。**A2A 不另开端口，不绕过安全链。**
+
+---
+
+## 三、与原 Runtime V2 的能力对齐
+
+**所有 Runtime V2 能力已完整迁移到统一 Runtime，不留缺口。**
+
+| Runtime V2 原能力 | 统一 Runtime 对应实现 | 状态 |
+|---|---|---|
+| ConnectorRuntime (多 Job 管理) | `ConnectorRuntimeService` | 功能增强（动态 API） |
+| FunctionRuntime | Pipeline Transformer Engine | 功能替代 |
+| MeshRuntime | EventMeshServer 主进程 | 统一合并 |
+| HealthService | AdminClient.HealthService | 迁移 |
+| MonitorService (SourceMonitor / SinkMonitor) | AdminClient.MonitorService + PipelineMonitor | 迁移 + 扩展 |
+| VerifyService | AdminClient.VerifyService + Pipeline 埋点 | 迁移 |
+| StatusService | AdminClient.StatusService | 迁移 |
+| MetaStorage | OffsetStore (RocksDB) | 简化重构 |
+| RuntimeInstance (启停模型) | EventMeshServer 生命周期 | 统一合并 |
+| Admin Server gRPC BiStream | AdminClient | 迁移 |
+| 独立进程隔离 | 单进程 + ClassLoader 隔离 + 独立线程池 | 架构简化 |
+
+---
+
+## 四、Pipeline 引擎详细设计
+
+> ⚠️ **安全铁律**：AuthFilter / RateLimitFilter / AclFilter 是 Pipeline 的内置前置 Filter，**所有协议入口（TCP/HTTP/gRPC/A2A）和 Connector 数据流** 都强制经过同一安全链。不存在绕过通道。旧架构 Connector 通过 BlockingQueue 直接旁路的问题是统一 Runtime 的核心修复点。
+
+### 4.1 FilterEngine
+
+**责任链模式，每个 Filter 独立判断是否放行。执行顺序固定，不可跳过。**
+
+```java
+interface PipelineFilter {
+    /**
+     * @return true = 放行，false = 丢弃
+     */
+    boolean filter(CloudEvent event, PipelineContext ctx);
+}
+```
+
+**内置 Filter（按执行顺序）：**
+
+| 序号 | Filter | 职责 | 可禁用 |
+|------|------|------|--------|
+| 1 | AuthFilter | 认证鉴权（Token / AK/SK） | 否（安全强依赖） |
+| 2 | RateLimitFilter | 频率限制（per-topic / per-client） | 可（按需关闭） |
+| 3 | ProtocolFilter | 协议合规校验（CloudEvents 格式检查） | 否（数据规范） |
+| 4 | RuleFilter | 自定义规则匹配（用户配置的匹配规则） | 可（无规则时跳过） |
+| 5 | AclFilter | 访问控制列表（IP/Client/Topic 白名单） | 否（安全强依赖） |
+| 6 | SizeLimitFilter | 消息体大小限制 | 可（按需关闭） |
+
+**AuthFilter 和 AclFilter 不可被 bypass：** 它们是 Pipeline 链的硬性前置位。即使在 `SHARED` 线程池模式下，消息也必须先经过这两个 Filter 才能进入 Transformer/Router。这是统一 Runtime 相比旧架构（Connector 数据流绕过安全策略）的核心安全保证。
+
+### 4.2 TransformerEngine
+
+**消息格式转换、字段映射、丰富化处理。**
+
+```java
+interface PipelineTransformer {
+    CloudEvent transform(CloudEvent event, PipelineContext ctx);
+}
+```
+
+**内置 Transformer：**
+
+| Transformer | 职责 |
+|-------------|------|
+| ProtocolTransformer | 协议格式互转（HTTP ↔ CloudEvents ↔ gRPC） |
+| FieldMappingTransformer | 字段映射（用户配置的字段映射规则） |
+| EnrichmentTransformer | 消息丰富化（附加 metadata、时间戳、trace 信息） |
+| EncryptionTransformer | 敏感字段加密/脱敏 |
+| CompressionTransformer | 消息体压缩 |
+
+### 4.3 RouterEngine
+
+**根据消息属性路由到目标 Topic/Queue。**
+
+```java
+interface PipelineRouter {
+    /**
+     * @return 目标 Topic 列表，空列表 = 不路由
+     */
+    List<String> route(CloudEvent event, PipelineContext ctx);
+}
+```
+
+**路由规则：**
+
+| 规则类型 | 说明 |
+|----------|------|
+| Static Route | 固定 Topic 映射 |
+| Header Route | 根据 CloudEvent Header 字段路由 |
+| Content Route | 根据消息体内容路由（JSONPath 表达式） |
+| Broadcast Route | 广播到多个 Topic |
+| Dead Letter Route | 处理失败路由到 DLQ |
+
+---
+
+## 五、配置体系
+
+### 统一配置项（CommonConfiguration）
+
+```properties
+# ── Connector Runtime ──
+eventmesh.connector.plugin.enabled=true
+eventmesh.connector.plugin.type=source              # source / sink
+eventmesh.connector.plugin.name=rocketmq-source

+
+# ── Admin Server ──
+eventmesh.admin.server.enabled=true
+eventmesh.admin.server.required=false               # true = 无 Admin 则启动失败
+eventmesh.admin.server.address=localhost:50051
+eventmesh.admin.server.registry.type=nacos           # nacos / etcd / static
+eventmesh.admin.server.heartbeat.interval.seconds=5

+eventmesh.pipeline.dlq.enabled=true
+eventmesh.pipeline.dlq.topic=eventmesh-dlq
+
+# ── A2A ──
+eventmesh.a2a.enabled=false                          # A2A 默认关闭
+eventmesh.a2a.gateway.port=8080
+eventmesh.a2a.registry.ttl.seconds=30
+eventmesh.a2a.sse.max.connections=1000
+```
+
+---
+
+## 六、部署模型
+
+### 单进程部署（默认）
+
+```bash
+# 启动 EventMesh 统一 Runtime
+cd eventmesh-dist
+bin/start.sh
+
+# 一个进程包含：
+# · TCP Server (端口 10000)
+# · HTTP Server (端口 8080)
+# · gRPC Server (端口 50051)
+# · Connector Runtime (内嵌)
+# · Admin Client (gRPC BiStream → Admin Server)
+# · A2A Gateway (复用 HTTP Server 端口 8080，路由 /a2a/*)
+# · Pipeline 处理链 (Filter → Transformer → Router)
+```
+
+### 多实例部署（集群）
+
+```
+┌─────────────────────────────────────────┐
+│              Admin Server               │
+│    (Job 调度 · 指标汇总 · 状态管理)       │
+└─────────────────────────────────────────┘
+         │              │              │
+    gRPC BiStream  gRPC BiStream  gRPC BiStream
+         │              │              │
+  ┌──────▼──────┐ ┌─────▼──────┐ ┌─────▼──────┐
+  │ Runtime #1  │ │ Runtime #2 │ │ Runtime #3 │
+  │ Connector A │ │ Connector B│ │ Connector C │
+  │ Connector D │ │            │ │ Connector E │
+  └─────────────┘ └────────────┘ └────────────┘
+```
+
+每个 Runtime 实例独立运行，Admin Server 统一调度 Job 分布。
+
+---
+
+## 七、可观测性
+
+### 指标体系
+
+| 指标类别 | 指标 | 采集方式 |
+|----------|------|----------|
+| Pipeline | `pipeline.ingress.latency` / `pipeline.egress.latency` | PipelineMonitor |
+| Pipeline | `pipeline.ingress.filtered.count` / `pipeline.ingress.total.count` | PipelineMonitor |
+| Connector | `connector.source.tps` / `connector.sink.tps` | ConnectorMonitor |
+| Connector | `connector.source.lag` / `connector.error.count` | ConnectorMonitor |
+| Runtime | `runtime.heap.used` / `runtime.cpu.usage` / `runtime.thread.count` | JVM MXBean |
+| A2A | `a2a.task.active` / `a2a.task.latency` / `a2a.sse.connections` | A2A Metrics |
+
+所有指标通过 AdminClient.MonitorService 每 30s 上报到 Admin Server，Admin Server 可对接 Prometheus / Grafana。
+
+### 链路追踪
+
+每个 CloudEvent 携带 `traceparent` 和 `tracestate`（W3C Trace Context），Pipeline 各阶段自动传播 Trace ID，实现端到端链路追踪。
+
+---
+
+## 八、故障处理
+
+### Connector 故障隔离
+
+```
+每个 Connector 实例:
+  · 独立线程池（可配置大小）
+  · ClassLoader 隔离（插件 jar 独立加载）
+  · try-catch 边界（异常不传播到主进程）
+  · 自动重试（指数退避，可配置最大重试次数）
+  · 连续失败 N 次 → 自动暂停 + 告警
+```
+
+### Admin Server 降级
+
+```
+eventmesh.admin.server.required=false:
+  Admin Server 不可达 → Runtime 正常运行，无心跳/指标上报
+  Admin Server 恢复 → 自动重连，补报积压状态
+
+eventmesh.admin.server.required=true:
+  Admin Server 不可达 → Runtime 启动失败（严格模式）
+```
+
+### Offset 容灾
+
+```
+正常流程:
+  写本地 RocksDB → 定时同步远程 Admin Server
+
+故障恢复:
+  1. 尝试本地 RocksDB 恢复（最快）
+  2. 本地无数据 → 尝试远程 Admin Server 拉取
+  3. 远程也无 → 使用 connector 配置的 auto.offset.reset
+```
+
+---
+
+## 九、测试覆盖要求
+
+| 测试类别 | 覆盖范围 | 关键场景 |
+|----------|----------|----------|
+| 单元测试 | Pipeline Engine (Filter/Transformer/Router) | 正常流程、filter 丢弃、transform 异常、路由到 DLQ |
+| 单元测试 | ConnectorRuntimeService | 多 Connector 注册/启停/卸载 |
+| 单元测试 | OffsetStore | RocksDB 读写、flush、恢复 |
+| 单元测试 | AdminClient | 心跳/Monitor/Verify 上报、指令接收 |
+| 集成测试 | 端到端消息流 | TCP→Pipeline→MQ→Pipeline→HTTP |
+| 集成测试 | Connector Source→Sink | 完整 Source→Pipeline→MQ→Pipeline→Sink 链路 |
+| 集成测试 | Offset 恢复 | Connector 重启后 Offset 恢复验证 |
+| 集成测试 | Admin Server 降级 | Admin 不可达时 Runtime 正常运行 |
+| 集成测试 | 多 Connector 并行 | ≥2 个 Connector 同时运行不互相影响 |
+| E2E 测试 | A2A 完整链路 | Agent→Gateway→Pipeline→MQ→Pipeline→Agent |
+| 性能测试 | 吞吐量基准 | 对比重构前后 TPS 变化 |
+| 性能测试 | Pipeline 延迟 | Filter/Transformer/Router 各阶段延迟 |
+

+
+### 11.8 本轮 Review 新发现的问题 / 建议
+
+以下条目是本次代码 review 相较原文档新识别的差距，建议后续 PR 逐条闭环：
+
+1. **⚠️ 存储实现与文档表述不一致：文档说 RocksDB，代码是文件持久化。**
+   - 现状：`FilePersistentOffsetStore` 已实现原子写、崩溃安全、定时 flush，功能上等价于 RocksDB 的本地持久化目标。
+   - 建议二选一：
+     - **A（推荐）**：把 §2.4、§8 及第一章 ASCII 图中的 "本地 RocksDB" 改为 "本地文件（原子替换 + 定时 flush）"，并保留"未来可扩展 RocksDB"的注释；
+     - **B**：新增真正的 `RocksDBOffsetStore` 实现，并把 `FilePersistentOffsetStore` 保留为轻量替代。
+   - 当前分支已按 A 方案的效果落地，仅文字未同步。
+
+2. **`EventMeshConnectorBootstrap` 与 `ConnectorRuntimeService` 未打通。**
+   - 现状：Bootstrap 通过 SPI 加载 **单一** Source 或 Sink 并挂 Pipeline；`ConnectorRuntimeService` 独立提供多 Connector 管理 API。
+   - 影响：设计文档 §2.2 承诺"单进程多 Connector 并行"，但从进程启动路径看仍是单实例；多 Connector 只能通过 `JobApiController` / `AdminCommandHandler` 动态注册。
+   - 建议：让 `EventMeshConnectorBootstrap.init()` 在检测到 `eventmesh.connector.plugin.multi.enabled=true` 或存在 `conf/connectors/*.yaml` 时委托给 `ConnectorRuntimeService`，把静态配置的多 Connector 一次性注册进去，与动态 API 共用同一管理路径。
+
+3. **`PipelineResult` 目标接口尚未落地。**
+   - 现状：`PipelineFilter.filter()` 返回 boolean，`PipelineTransformer.transform()` 返回 `CloudEvent`（null=DROP）。文档 §2.1 声明的 `PipelineResult { CONTINUE/DROP/RETRY/DLQ/FAIL }` 属于目标形态，尚未成为正式接口。
+   - 影响：`RETRY` / `DLQ` / `FAIL` 语义现阶段依赖 Processor 层胶水代码；`RetryContext` 已具备，但未在 Filter/Transformer 接口层暴露。
+   - 建议：拉一条独立 PR 引入 `PipelineResult`（新接口 + 老接口 default 适配），逐个 Filter/Transformer 迁移，避免大爆炸修改。
+
+4. **`VerifyService` / 数据校验链路只有骨架。**
+   - 现状：`AdminClient` 有 Verify 定时任务与上报点，但 Pipeline 内部尚缺显式采样埋点（如按抽样率写入 checksum、offset、payload hash 到 Admin Server）。
+   - 建议：在 `IngressProcessor.process()` 和 `EgressProcessor.process()` 加可选拦截钩子，走 `AdminClient.reportVerify(...)`；配合 §5 配置项 `eventmesh.connector.verify.enabled` 与采样率参数。
+
+5. **A2A 内部传输仍是 `InMemoryA2AMessageTransport`。**
+   - 现状：跨节点场景需要复用 Storage Plugin（Kafka/RocketMQ）承载 A2A 消息，当前只有内存实现。
+   - 建议：新增 `StorageBackedA2AMessageTransport`，通过 `A2ATopicFactory` 生成的内部 Topic 走 Storage Plugin；单机场景仍走 InMemory 以降延迟。
+
+6. **`ConnectorRuntimeService` 与 `AdminCommandHandler` 的一致性视图缺失。**
+   - `AdminCommandHandler` 处理 `JOB.*` 指令时，最终应通过 `ConnectorRuntimeService` 落地；review 中未见二者的直接调用链证据（可能通过 `JobInfo` 中转，需要在集成测试中确认）。
+   - 建议：补充集成测试 `AdminCommand → ConnectorRuntimeService → EventMeshConnectorBootstrap Pipeline` 全链路。
+
+7. **多协议接入的实际证据 vs 文档 "全部协议路径统一"。**
+   - Review 只直接确认了 TCP/HTTP/gRPC Publish/Batch/Send 系列 Processor 存在；Consumer 侧（`ClientGroupWrapper` 等）虽在文档提到但未在本轮逐行核对。
+   - 建议：补一份"Pipeline 接入清单"矩阵，逐 Processor 打勾（issue/PR 描述里带出即可）。
+
+8. **性能基线缺失。**
+   - 目前只有单元测试，缺少 `JMH` 或压测脚本；重构声称"消除双运行时开销"，需要数据背书。
+   - 建议：至少提供一份 100k msg × 1KB 场景下的 TPS + P99 延迟对比（重构前 v1、v1+v2、当前统一 Runtime）。
+
+9. **配置项文档 vs 代码字段可能存在偏差。**
+   - 文档 §5 列举了近 20 个 `eventmesh.*` 配置项，本轮未对 `CommonConfiguration.java` 全字段做穷举校对。
+   - 建议：由代码 owner 补一份 "配置项 → 代码字段 → 默认值" 的对照表，作为附录纳入本文档。
+
+10. **测试样本量不足 & CI 缺失说明。**
+    - `ConnectorExtendedTest` / `AdminJobExtendedTest` 是好开端，但没有明确的"每 PR 必跑的集成测试子集"。
+    - 建议：在 `.github/workflows` 中加一个 `unified-runtime-check` job，锁定必跑用例。
+

+
+## 十二、设计原则总结
+
+1. **统一数据面**：所有消息（TCP/HTTP/gRPC/A2A/Connector）走同一 Ingress/Egress Pipeline
+2. **完整控制面**：Admin Server 通信能力（Health/Monitor/Status/Verify）完整保留
+3. **单进程部署**：一个 JVM 进程承载全部能力，消除 runtime-v1/v2 进程隔离开销
+4. **Connector 内嵌 + 隔离**：内嵌到主进程，但 ClassLoader/线程池隔离保证故障不扩散
+5. **Exactly-Once**：本地 RocksDB + 远程 Admin Server 双写 Offset
+6. **可降级**：Admin Server 不可达时 Runtime 可独立运行（非严格模式）
+7. **可观测**：指标 + 链路追踪 + 健康检查全覆盖
+8. **A2A 原生**：Pipeline 原生支持 A2A Agent 消息流，不额外建立处理路径

+ *       Fault isolation guaranteed — one slow connector does not block others.</li>
+ *   <li><b>SHARED</b>: All connectors share a single global pool.
+ *       Higher resource utilization but head-of-line blocking risk.</li>
+ * </ul>
+ *
+ * <h3>Connector Limit</h3>
+ * Registration is capped at {@code maxConnectors}. Exceeding the limit
+ * throws {@link ConnectorLimitExceededException}.
+ *
+ * <h3>Fault Isolation</h3>
+ * Each connector runs within a try-catch boundary. Exceptions in one
+ * connector do NOT propagate to other connectors or the main process.
+ * After {@code maxRetry} consecutive failures, the connector is auto-paused
+ * and an alert is raised.
