A unified server management framework for data processing component

Project description

数据处理平台组件基类

统一的数据处理组件开发框架,标准化入参、出参和执行入口。

功能特性

  • 统一的接口规范(继承 BaseService,实现 process 方法)
  • 配置加载(本地 JSON / HTTP 远程 JSON / base64 编码 URL)
  • 动态 pip 包安装(runtime_env.pip
  • 结构化日志(自动包含服务名称和版本,兼容 Ray)
  • 结果投递(上传 OSS + MNS 通知,自动重试)
  • 日志上传 OSS(上传后自动删除本地文件)
  • 数据跟踪(track 模块,两段式上报到 MNS 顺序队列)
  • 工具函数(tools 模块,环境变量提取、bag 路径解析)

安装

pip install hello-datap-component-base

快速上手

详见 快速开始 | 用户手册

from hello_datap_component_base import BaseService

class MyService(BaseService):
    async def process(self, data: dict) -> dict:
        return {"result": data.get("value", 0) * 2}
component_manager start config.json

配置文件

{
  "name": "my-service",
  "version": "1.0.0",
  "work_flow_id": 123,
  "work_flow_instance_id": 456,
  "task_id": "task-001",
  "runtime_env": {
    "pip": ["requests>=2.25.0"],
    "env_vars": {
      "LOG_LEVEL": "INFO",
      "MNS_ENDPOINT": "https://your-account.mns.cn-shanghai.aliyuncs.com",
      "MNS_ACCESS_KEY_ID": "your-key-id",
      "MNS_ACCESS_KEY_SECRET": "your-key-secret",
      "OSS_ENDPOINT_FOR_LOG": "https://oss-cn-shanghai.aliyuncs.com",
      "OSS_ACCESS_KEY_ID_FOR_LOG": "your-key-id",
      "OSS_ACCESS_KEY_SECRET_FOR_LOG": "your-key-secret",
      "OSS_BUCKET_NAME_FOR_LOG": "your-bucket"
    }
  },
  "params": {
    "field1": "value1"
  }
}
字段 类型 必需 说明
name string 服务名称
version string 服务版本
work_flow_id int 工作流 ID
work_flow_instance_id int 工作流实例 ID
task_id string 任务 ID
runtime_env.pip list 启动前自动安装的 pip 包
runtime_env.env_vars dict 注入到进程的环境变量
params dict 传递给 process 方法的输入数据

返回结果格式

{
    "code": 0,
    "message": "success",
    "processing_time": 0.123,
    "data": {
        "work_flow_id": 123,
        "work_flow_instance_id": 456,
        "task_id": "task-001",
        "out_put": { "...用户返回的结果..." }
    }
}

异常时 code=-1message 为错误信息,out_putnull

结果投递(MNS + OSS)

配置 MNS 和 OSS 环境变量后,框架自动完成:

  1. 完整结果 JSON → 上传到 oss://infra-hads-artifacts/data-process-platform/task-result/{task_id}.json
  2. OSS 地址 → 发送到 MNS 队列

避免 MNS 64KB 消息限制。未配置则静默跳过。

数据跟踪(track)

from hello_datap_component_base import track

track.log(data=bag_path)                  # 任务开始
track.log(data=bag_path, status=1)        # 任务成功(status: 1=成功 2=失败)

通过 data + data_type + pipeline_instance_id + node_task_id 四元组判断插入/更新。

环境变量:DATA_TRACK_PIPELINE_IDDATA_TRACK_PIPELINE_INSTANCE_IDDATA_TRACK_NODE_IDDATA_TRACK_NODE_TASK_IDDATA_TRACK_COMPONENT_VERSIONDATA_TRACK_PRIORITYDATA_TRACK_EXECUTORDATA_TRACK_RUN_TYPEDATA_TRACK_MNS_QUEUE_NAME。MNS 认证复用 MNS_ENDPOINT 等。

工具函数(tools)

from hello_datap_component_base import tools

env_vars = tools.extract_specific_env_vars()           # 提取框架相关环境变量
vehicle  = tools.get_vehicle_id_from_bag(bag_path)     # "1_002"
date     = tools.get_date_from_bag(bag_path)           # "20260119"
package  = tools.get_package_name_from_bag(bag_path)   # "1_002_20260119-151708"

日志

from hello_datap_component_base import logger

logger.info("处理中...")
logger.error(f"失败: {e}")

或在服务类内使用 self.logger。日志自动包含服务名称和版本,兼容 Ray。

命令行

component_manager start <config_path>       # 启动服务
component_manager list                       # 列出服务类
component_manager validate <config_path>     # 验证配置
component_manager test <config_path> [data]  # 测试服务

也可用 python -m hello_datap_component_base.cli 替代 component_manager
