## 二、设计原则
|
||||
|
||||
| 原则 | 说明 |
|
||||
|------|------|
|
||||
| **南向屏蔽，北向统一** | 协议层允许混乱，业务层必须干净（继承现有铁律） |
|
||||
| **JetLinks 为主骨架** | 规则引擎、条件引擎、SPI 扩展采用 JetLinks 模式 |
|
||||
| **ThingsBoard 补关键设计** | 属性三元分类、RPC 状态机、EntityRelation、告警状态机 |
|
||||
| **保留现有消息总线** | Local/Redis/RocketMQ 三实现不动，消费端接入新引擎 |
|
||||
| **渐进式迁移** | 新旧规则可并行运行，不要求一次性切换 |

**场景：温度传感器上报 → 异常检测 → 告警 → 通知**
|
||||
|
||||
```
|
||||
1. 传感器通过 MQTT 上报 {"temperature": 52, "humidity": 18}
|
||||
2. Gateway ALink Codec 解码 → IotDeviceMessage
|
||||
3. 消息总线投递 → IotDeviceMessageSubscriber 消费
|
||||
4. 属性写入 Redis（CLIENT scope）+ 时序库存储
|
||||
5. 规则引擎匹配：该设备属于"安防子系统"，命中 2 条规则链
|
||||
6. 规则链 A（场景联动）：
|
||||
├── Trigger: device_property（温度上报）
|
||||
├── Enrich: 读取近 1 小时均值温度 → metadata.avgTemp = 38
|
||||
├── Condition: temperature > 40 → true
|
||||
├── ShakeLimit: 30 秒内第 3 次触发 → 通过
|
||||
├── AgentRequest: anomaly-detector → {"level":"critical","reason":"偏离均值 14°C"}
|
||||
├── AlarmTrigger: 创建 CRITICAL 告警（upsert Record + append History）
|
||||
├── 告警传播: 安防子系统 → 1 楼 → 楼宇 A
|
||||
└── Notify: 短信通知安防负责人
|
||||
7. 规则链 B（数据转发）：
|
||||
├── Trigger: device_property
|
||||
└── HttpPush: 推送到第三方监控平台

## 十二、Agent 协作节点
|
||||
|
||||
> 参考：ThingsBoard 4.2 AI Request Node 思路 + ACP 智能体通信协议
|
||||
> 本阶段在 IoT 模块内实现 Agent 调用能力，后续成熟后再抽取为平台级 `viewsh-module-ai` 模块。
|
||||
|
||||
### 12.1 设计背景
|
||||
|
||||
TB 4.2 新增了 AI Request 规则节点，直接对接 LLM API（OpenAI/Gemini 等）。我们的场景不同：不直接对接模型，而是通过 **ACP（Agent Communication Protocol）协议** 调用内部已有的 Agent 服务（数字员工），由 Agent 内部决定调用哪个模型、如何处理。
|
||||
|
||||
```
|
||||
TB 方式： 规则节点 ──→ LLM API（OpenAI/Gemini）
|
||||
我们的方式：规则节点 ──→ AgentCallService ──→ AcpClient ──→ Agent 服务（数字员工）
|
||||
└── 全部在 IoT 模块内，后续抽取为独立 ai 模块
|
||||
```
|
||||
|
||||
### 12.2 模块内部结构
|
||||
|
||||
Agent 调用相关代码放在 `viewsh-module-iot-biz` 的 `agent` 包下，与规则引擎同模块部署：
|
||||
|
||||
```
|
||||
viewsh-module-iot-biz/
|
||||
└── src/main/java/.../iot/
|
||||
├── rule/ ← 规则引擎（已有）
|
||||
│ └── action/
|
||||
│ └── AgentRequestAction.java ← 规则节点
|
||||
└── agent/ ← Agent 调用（新增）
|
||||
├── dal/
|
||||
│ ├── IotAgentServiceDO.java ← 实体
|
||||
│ └── IotAgentServiceMapper.java
|
||||
├── service/
|
||||
│ ├── IotAgentServiceService.java ← Agent 注册表 CRUD
|
||||
│ └── IotAgentCallService.java ← 调用编排（组装请求 + 调 ACP + 解析响应）
|
||||
├── client/
|
||||
│ ├── AcpClient.java ← ACP 协议客户端接口
|
||||
│ └── AcpHttpClient.java ← HTTPS 实现（先做同步，后续加 WSS/SSE）
|
||||
└── controller/
|
||||
└── IotAgentServiceController.java ← 管理后台 CRUD
|
||||
```
|
||||
|
||||
**后续抽取路径**：当 Ops 等其他模块也需要调 Agent 时，将 `agent/` 包整体迁移到 `viewsh-module-ai`，IoT 侧改为 Feign 调用。接口不变，只是调用方式从本地变远程。
|
||||

||||

### 12.5 核心实现
|
||||
|
||||
#### AcpClient（ACP 协议客户端）
|
||||
|
||||
```java
|
||||
/**
|
||||
* ACP 协议客户端 —— 封装与 Agent 的通信
|
||||
* 本阶段只实现 HTTPS 同步模式，后续按需扩展 WSS/SSE
|
||||
*/
|
||||
public interface AcpClient {
|
||||
/**
|
||||
* 同步调用：建 Session → 发消息 → 等响应 → 关 Session
|
||||
*/
|
||||
AcpResponse call(AcpRequest request);
|
||||
}
|
||||
|
||||
@Data @Builder
|
||||
class AcpRequest {
|
||||
private String endpoint; // ACP 接入点地址
|
||||
private String targetAid; // 目标 Agent AID
|
||||
private String authMode;
|
||||
private String authConfig;
|
||||
private JsonNode payload; // 业务数据
|
||||
private Map<String, String> metadata; // 附加上下文
|
||||
private int timeoutSeconds;
|
||||
}
|
||||
|
||||
@Data
|
||||
class AcpResponse {
|
||||
private boolean success;
|
||||
private String sessionId;
|
||||
private JsonNode data; // Agent 返回结果
|
||||
private String errorMessage;
|
||||
private long latencyMs;
|
||||
}
|
||||
```
|
||||
|
||||
#### IotAgentCallService（调用编排）
|
||||
|
||||
```java
|
||||
@Service
|
||||
public class IotAgentCallService {
|
||||
|
||||
private final IotAgentServiceService agentServiceService;
|
||||
private final AcpClient acpClient;
|
||||
|
||||
/**
|
||||
* 调用 Agent 服务
|
||||
* @param agentCode Agent 编码
|
||||
* @param payload 业务数据
|
||||
* @param context 调用上下文（来源、设备信息等）
|
||||
* @param timeoutOverride 超时覆盖（null 则使用 Agent 默认超时）
|
||||
*/
|
||||
public AgentCallResult call(String agentCode, JsonNode payload,
|
||||
Map<String, String> context, Integer timeoutOverride) {
|
||||
// 1. 查询 Agent 配置
|
||||
IotAgentServiceDO agent = agentServiceService.getByCode(agentCode);
|
||||
if (agent == null || agent.getStatus() != 1) {
|
||||
return AgentCallResult.failure("Agent not found or disabled: " + agentCode);
|
||||
}
|
||||
|
||||
// 2. ACP 调用
|
||||
AcpRequest request = AcpRequest.builder()
|
||||
.endpoint(agent.getAcpEndpoint())
|
||||
.targetAid(agent.getAgentAid())
|
||||
.authMode(agent.getAuthMode())
|
||||
.authConfig(agent.getAuthConfig())
|
||||
.payload(payload)
|
||||
.metadata(context)
|
||||
.timeoutSeconds(timeoutOverride != null ? timeoutOverride : agent.getTimeoutSeconds())
|
||||
.build();
|
||||
|
||||
AcpResponse response = acpClient.call(request);
|
||||
|
||||
// 3. 封装结果
|
||||
return AgentCallResult.of(response);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### AgentRequestAction（规则引擎 SPI 节点）
|
||||
|
||||
```java
|
||||
@Component
|
||||
public class AgentRequestAction implements ActionProvider {
|
||||
|
||||
private final IotAgentCallService agentCallService;
|
||||
|
||||
@Override
|
||||
public String getType() { return "agent_request"; }
|
||||
|
||||
@Override
|
||||
public ActionResult execute(RuleContext ctx, JsonNode config) {
|
||||
// 1. 解析配置
|
||||
String agentCode = config.get("agentCode").asText();
|
||||
JsonNode payload = resolvePayload(config.get("payload"), ctx);
|
||||
Integer timeout = config.has("timeoutSeconds")
|
||||
? config.get("timeoutSeconds").asInt() : null;
|
||||
|
||||
// 2. 构建调用上下文
|
||||
Map<String, String> context = Map.of(
|
||||
"source", "iot-rule-engine",
|
||||
"deviceId", String.valueOf(ctx.getDeviceId()),
|
||||
"productId", String.valueOf(ctx.getProductId()),
|
||||
"subsystemId", String.valueOf(ctx.getSubsystemId()),
|
||||
"ruleChainId", String.valueOf(ctx.getRuleChainId())
|
||||
);
|
||||
|
||||
// 3. 调用
|
||||
AgentCallResult result = agentCallService.call(agentCode, payload, context, timeout);
|
||||
|
||||
// 4. 结果注入
|
||||
if (result.isSuccess()) {
|
||||
String outputTo = config.path("outputTo").asText("metadata.agentResult");
|
||||
injectResult(ctx, outputTo, result.getData());
|
||||
return ActionResult.success();
|
||||
}
|
||||
return ActionResult.failure(result.getErrorMessage());
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 12.6 模板变量解析
|
||||
|
||||
规则引擎统一提供模板解析能力（Agent 节点与脚本节点共用），借鉴 TB 的 `TbNodeUtils.processPattern()`：
|
||||
|
||||
| 模板语法 | 含义 | 示例 |
|
||||
|---------|------|------|
|
||||
| `$[identifier]` | 消息数据字段 | `$[temperature]` → 设备上报的温度值 |
|
||||
| `$[*]` | 整个消息体 JSON | 传递全部上报数据 |
|
||||
| `${key}` | 元数据字段 | `${deviceName}` → 设备名称 |
|
||||
|
||||
### 12.7 节点配置格式
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "agent_request",
|
||||
"config": {
|
||||
"agentCode": "anomaly-detector",
|
||||
"payload": {
|
||||
"taskType": "anomaly_detection",
|
||||
"deviceName": "${deviceName}",
|
||||
"subsystem": "${subsystemCode}",
|
||||
"data": {
|
||||
"temperature": "$[temperature]",
|
||||
"humidity": "$[humidity]"
|
||||
},
|
||||
"context": {
|
||||
"recentAvgTemp": "${avgTemp}",
|
||||
"deviceModel": "${productName}"
|
||||
}
|
||||
},
|
||||
"timeoutSeconds": 60,
|
||||
"outputTo": "metadata.agentResult"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 12.8 Agent 结果在规则链中的使用
|
||||
|
||||
Agent 返回的结果注入 `metadata.agentResult` 后，后续节点可直接引用：
|
||||
|
||||
```
|
||||
设备上报 → [Enrich: 读取近1小时均值]
|
||||
→ [AgentRequest: anomaly-detector]
|
||||
→ [Expression: metadata.agentResult.level == 'critical']
|
||||
├── true → [AlarmTrigger: 严重告警]
|
||||
└── false → [Expression: metadata.agentResult.level == 'warning']
|
||||
├── true → [Notify: 发送预警通知]
|
||||
└── false → 结束
|
||||
```
|
||||
|
||||
### 12.9 典型业务场景
|
||||
|
||||
| 场景 | Agent | 触发方式 | Agent 输入 | Agent 输出 | 后续动作 |
|
||||
| ------ | ---------------------- | ------- | --------- | ----------------- | --------- |
|
||||
| 设备异常检测 | anomaly-detector | 属性上报 | 温湿度+历史均值 | level + reason | 告警/通知 |
|
||||
| 保洁质量验收 | clean-quality-checker | 保洁完成事件 | 区域图片+清洁标准 | pass/fail + score | 标记完成/派返工单 |
|
||||
| 能耗优化 | energy-advisor | 定时（每小时） | 用电数据+设备列表 | 调度建议 | 设备控制指令 |
|
||||
| 预测性维护 | predictive-maintenance | 定时（每天） | 30 天运行参数 | 剩余寿命+劣化趋势 | 提前告警 |
|

### 1.3 内置策略
|
||||
### 1.3 CTSDB 实现（基于 InfluxDB 协议）
|
||||
|
||||
| 策略 ID | 说明 | 适用场景 |
|
||||
| ----------------- | --------------- | -------------- |
|
||||
| `tdengine-column` | 列模式（现有方案），每属性一列 | 属性固定、查询频繁 |
|
||||
| `tdengine-row` | 行模式，每属性一行 | 属性动态变化、物模型频繁变更 |
|
||||
| 维度 | 说明 |
|
||||
|------|------|
|
||||
| SDK | `influxdb-client-java` |
|
||||
| 协议 | HTTP REST API（`http://host:8086`） |
|
||||
| 认证 | Token 方式 |
|
||||
| 查询语言 | Flux |
|
||||
| 建表 | Schema-on-write（自动，无需预建） |
|
||||
| 写入 | 异步批量：1000 条/批 + 1s 自动刷新 + 3 次重试 |
|
||||
| 防注入 | `FluxQuerySanitizer` 转义特殊字符 |
|
||||
| 多租户 | Flux 查询中 `tenant_id` 字段过滤 |
|
||||
|
||||
### 1.4 列模式 vs 行模式
|
||||
|
||||
**列模式（现有，保留为默认）**：
|
||||
```sql
|
||||
CREATE STABLE product_property_{productId} (
|
||||
ts TIMESTAMP, report_time TIMESTAMP,
|
||||
temperature INT, humidity FLOAT, status TINYINT -- 每属性一列
|
||||
) TAGS (device_id BIGINT);
|
||||
```
|
||||
- 优点：查询快，单行包含所有属性
|
||||
- 缺点：物模型变更需 ALTER TABLE，TDengine 不支持缩短字段
|
||||
|
||||
**行模式（新增）**：
|
||||
```sql
|
||||
CREATE STABLE product_property_row_{productId} (
|
||||
ts TIMESTAMP, report_time TIMESTAMP,
|
||||
identifier NCHAR(64), -- 属性标识符
|
||||
value_int INT, -- 整型值
|
||||
value_float FLOAT, -- 浮点值
|
||||
value_double DOUBLE, -- 双精度值
|
||||
value_bool TINYINT, -- 布尔值
|
||||
value_str NCHAR(1024), -- 字符串值
|
||||
scope TINYINT -- 属性域（1=CLIENT, 2=SERVER, 3=SHARED）
|
||||
) TAGS (device_id BIGINT);
|
||||
```
|
||||
- 优点：物模型变更无需 DDL，属性可任意扩展
|
||||
- 缺点：查询需按 identifier 过滤，同时查多属性需 PIVOT
|
||||
|
||||
### 1.5 产品级配置
|
||||
|
||||
```sql
|
||||
ALTER TABLE iot_product ADD COLUMN store_policy VARCHAR(32) DEFAULT 'tdengine-column';
|
||||
```yaml
|
||||
# CTSDB 连接配置
|
||||
viewsh.iot.tsdb.ctsdb:
|
||||
url: http://${CTSDB_HOST:localhost}:${CTSDB_PORT:8086}
|
||||
token: ${CTSDB_TOKEN:}
|
||||
org: ${CTSDB_ORG:aiot}
|
||||
bucket: ${CTSDB_BUCKET:aiot_platform}
|
||||
```
|
||||
|
||||
`ThingsDataStorageRouter` 按 productId 路由到对应策略：
|
||||
```java
|
||||
ThingsDataStorageStrategy getStrategy(Long productId) {
|
||||
String policy = productService.getProduct(productId).getStorePolicy();
|
||||
return strategyMap.get(policy); // 策略注册表
|
||||
}
|
||||
### 1.4 TDengine 实现
|
||||
|
||||
| 维度 | 说明 |
|
||||
|------|------|
|
||||
| SDK | `taos-jdbcdriver` 3.7.9 |
|
||||
| 协议 | JDBC（WebSocket / REST） |
|
||||
| 认证 | 用户名密码 |
|
||||
| 查询语言 | TDengine SQL |
|
||||
| 建表 | 需要预建超级表（CREATE STABLE） |
|
||||
| 写入 | 同步写入（通过 Mapper XML） |
|
||||
| 多租户 | `@InterceptorIgnore` 绕过 JSqlParser |
|
||||
|
||||
### 1.5 数据模型（两套实现共用）
|
||||
|
||||
```
|
||||
measurement/超级表: device_message
|
||||
├── TAG: device_id
|
||||
└── FIELDS: id, report_time, tenant_id, server_id, upstream,
|
||||
reply, identifier, request_id, method, params, data, code, msg
|
||||
|
||||
measurement/超级表: product_property_{productId}
|
||||
├── TAG: device_id
|
||||
└── FIELDS: report_time + 动态属性列（从物模型生成）
|
||||
```
|
||||
|
||||
### 1.6 物模型类型映射
|
||||
|
||||
| 物模型类型 | CTSDB (InfluxDB) | TDengine |
|
||||
|---------|-----------------|----------|
|
||||
| INT | INT | INT |
|
||||
| FLOAT | FLOAT | FLOAT |
|
||||
| DOUBLE | DOUBLE | DOUBLE |
|
||||
| ENUM | TINYINT | TINYINT |
|
||||
| BOOL | BOOL | TINYINT |
|
||||
| TEXT | STRING | VARCHAR(1024) |
|
||||
| DATE | TIMESTAMP | TIMESTAMP |
|
||||
| STRUCT | STRING (JSON) | VARCHAR(1024) |
|
||||
| ARRAY | STRING (JSON) | VARCHAR(1024) |

|
||||
|
||||
## 二、写入缓冲（借鉴 JetLinks PersistenceBuffer）
|
||||
## 二、v2.0 存储扩展
|
||||
|
||||
### 2.1 设计动机
|
||||
### 2.1 新增时序表
|
||||
|
||||
设备高频上报时（如 1Hz × 1000 台），每条消息直接写 TDengine 会产生大量小批次 INSERT。引入写入缓冲，批量合并后写入。
|
||||
在现有 `device_message` 和 `product_property_*` 基础上，v2.0 需新增两张时序表，同样遵循 DAO 接口双实现模式：
|
||||
|
||||
### 2.2 PersistenceBuffer 设计
|
||||
| 时序表 | 用途 | TAG | 关键字段 |
|
||||
|--------|------|-----|---------|
|
||||
| `alarm_history` | 告警状态变化归档 | device_id | alarm_record_id, severity, state, trigger_data |
|
||||
| `rule_debug_log` | 规则调试日志 | device_id | rule_chain_id, node_id, input_data, output_data, duration_ms |
|
||||
|
||||
需新增对应 DAO 接口：
|
||||
|
||||
```java
|
||||
// 告警历史时序存储
|
||||
interface IotTsDbAlarmHistoryDao {
|
||||
void insert(AlarmHistoryDO history);
|
||||
List<AlarmHistoryDO> selectByRecordId(Long alarmRecordId, TimeRange range);
|
||||
List<AlarmHistoryDO> selectByDeviceId(Long deviceId, TimeRange range);
|
||||
}
|
||||
|
||||
// 规则调试日志时序存储
|
||||
interface IotTsDbRuleDebugLogDao {
|
||||
void insert(RuleDebugLogDO log);
|
||||
List<RuleDebugLogDO> selectByChainId(Long ruleChainId, TimeRange range);
|
||||
}
|
||||
```
|
||||
|
||||
### 2.2 写入缓冲
|
||||
|
||||
CTSDB 侧已有 InfluxDB WriteApi 的异步批量写入（1000 条/批 + 1s 刷新），TDengine 侧需补齐 PersistenceBuffer：
|
||||
|
||||
```java
|
||||
class PersistenceBuffer<T> {
|
||||
// 配置
|
||||
int bufferSize = 200; // 数量触发阈值
|
||||
Duration bufferTimeout = Duration.ofSeconds(3); // 时间触发阈值
|
||||
int parallelism = 4; // 并行写出线程数
|
||||
int bufferSize; // 数量触发阈值
|
||||
Duration bufferTimeout; // 时间触发阈值
|
||||
int parallelism; // 并行写出线程数
|
||||
BlockingQueue<T> queue; // 内存队列
|
||||
ScheduledExecutorService timer;// 定时刷新
|
||||
|
||||
// 内部结构
|
||||
BlockingQueue<T> queue; // 内存队列
|
||||
ScheduledExecutorService timer; // 定时刷新
|
||||
|
||||
// 写入方法
|
||||
void write(T item) {
|
||||
queue.add(item);
|
||||
if (queue.size() >= bufferSize) {
|
||||
flush();
|
||||
}
|
||||
if (queue.size() >= bufferSize) { flush(); }
|
||||
}
|
||||
|
||||
// 批量刷出
|
||||
void flush() {
|
||||
List<T> batch = new ArrayList<>();
|
||||
queue.drainTo(batch, bufferSize);
|
||||
if (!batch.isEmpty()) {
|
||||
batchWriter.accept(batch); // 回调：批量写入 TDengine
|
||||
}
|
||||
if (!batch.isEmpty()) { batchWriter.accept(batch); }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2.3 应用点
|
||||
| 缓冲实例 | 写入目标 | bufferSize | timeout | 备注 |
|
||||
|---------|---------|-----------|---------|------|
|
||||
| 属性写入缓冲 | `product_property_*` | 200 | 3s | CTSDB 已内置批量，TDengine 需要 |
|
||||
| 消息日志缓冲 | `device_message` | 500 | 5s | 同上 |
|
||||
| 告警历史缓冲 | `alarm_history` | 100 | 3s | 新增 |
|
||||
| 规则调试日志缓冲 | `rule_debug_log` | 100 | 5s | 新增 |
|
||||
|
||||
| 缓冲实例 | 写入目标 | bufferSize | timeout |
|
||||
|---------|---------|-----------|---------|
|
||||
| 属性写入缓冲 | TDengine `product_property_*` | 200 | 3s |
|
||||
| 消息日志缓冲 | TDengine `device_message` | 500 | 5s |
|
||||
| 告警历史缓冲 | TDengine `alarm_history` | 100 | 3s |
|
||||
| 规则调试日志缓冲 | TDengine `rule_debug_log` | 100 | 5s |
|
||||
### 2.3 数据保留策略
|
||||
|
||||
| 时序表 | 建议保留期 | CTSDB 实现 | TDengine 实现 |
|
||||
|--------|----------|-----------|--------------|
|
||||
| `device_message` | 90 天 | Bucket Retention Policy | `KEEP 90d` |
|
||||
| `product_property_*` | 365 天 | Bucket Retention Policy | `KEEP 365d` |
|
||||
| `alarm_history` | 365 天 | Bucket Retention Policy | `KEEP 365d` |
|
||||
| `rule_debug_log` | 7 天 | Bucket Retention Policy | `KEEP 7d` |
|
||||
|
||||
### 2.4 属性作用域扩展
|
||||
|
||||
v2.0 引入属性三元分类（CLIENT/SERVER/SHARED），时序数据需新增 `scope` 维度：
|
||||
|
||||
- **CTSDB**：写入时增加 `scope` 字段（INT，作为 FIELD），查询时按 scope 过滤
|
||||
- **TDengine**：超级表增加 `scope TINYINT` 列
|
||||
|
||||
两套 DAO 实现的 `insert()` 方法均需接收 `AttributeScope` 参数。
|
||||
|
||||

|
||||
|
||||
## 三、TDengine 优化
|
||||
## 三、Redis 缓存优化
|
||||
|
||||
### 3.1 消息超级表优化
|
||||
|
||||
现有 `device_message` 表的 `params` 和 `data` 字段为 `NCHAR(2048)`，大消息会截断。
|
||||
|
||||
优化方案：
|
||||
```sql
|
||||
-- 增大到 4096，覆盖绝大多数场景
|
||||
ALTER STABLE device_message MODIFY COLUMN params NCHAR(4096);
|
||||
ALTER STABLE device_message MODIFY COLUMN data NCHAR(4096);
|
||||
```
|
||||
|
||||
### 3.2 新增超级表
|
||||
|
||||
```sql
|
||||
-- 告警历史（两级告警的时序部分）
|
||||
CREATE STABLE IF NOT EXISTS alarm_history (
|
||||
ts TIMESTAMP,
|
||||
alarm_record_id NCHAR(64),
|
||||
alarm_config_id BIGINT,
|
||||
severity TINYINT,
|
||||
state NCHAR(16),
|
||||
trigger_data NCHAR(4096),
|
||||
details NCHAR(2048),
|
||||
operator NCHAR(64),
|
||||
remark NCHAR(256)
|
||||
) TAGS (device_id BIGINT);
|
||||
|
||||
-- 规则调试日志
|
||||
CREATE STABLE IF NOT EXISTS rule_debug_log (
|
||||
ts TIMESTAMP,
|
||||
rule_chain_id BIGINT,
|
||||
node_id BIGINT,
|
||||
node_type NCHAR(64),
|
||||
input_data NCHAR(4096),
|
||||
output_data NCHAR(4096),
|
||||
duration_ms INT,
|
||||
success BOOL,
|
||||
error_msg NCHAR(512)
|
||||
) TAGS (device_id BIGINT);
|
||||
```
|
||||
|
||||
### 3.3 数据保留策略
|
||||
|
||||
| 超级表 | 建议保留期 | 配置方式 |
|
||||
|--------|----------|---------|

|
||||
| `product_property_*` | 365 天 | TDengine `KEEP 365d` |
