curiositech/windags-skills

Apache Airflow DAG、運算子、SLA 監控和工作流程編排。啟用條件:Airflow、DAG、operator、sensor、scheduler、task dependency、SLA、backfill、XCom。不適用於:dbt 轉換(請使用 dbt-analytics-engineer)、串流管道(請使用 streaming-pipeline-architect)。

windags-skills 是什麼?

此技能(curiositech/windags-skills)專注於 Apache Airflow 的 DAG 設計與操作,提供可靠的資料管道編排,包含依賴管理、SLA 監控與重試機制。它支援 Airflow 2.10+、MWAA 和 Cloud Composer 等平台,並涵蓋 TaskFlow API、動態任務映射(Dynamic Task Mapping)以及與 dbt 的整合模式。技能內容透過詳細的程式碼範例展示如何使用 TaskFlow API 定義 DAG、設定排程與重試、配置 SLA,以及透過 XCom 傳遞元資料而非大型資料。此外,它明確指出反模式(如大型任務、意外啟用 catchup)並提供品質檢查清單,幫助開發者避免常見錯誤並提升管道的可靠性與可維護性。

Airflow DAG 編排器

設計並操作 Apache Airflow DAG,以實現具備正確依賴管理、SLA 和監控功能的可靠資料管道編排。

啟用觸發條件

啟用於:「Airflow」、「DAG」、「operator」、「sensor」、「scheduler」、「task dependency」、「SLA」、「backfill」、「XCom」、「TaskFlow API」、「MWAA」、「Cloud Composer」

**不適用於:**dbt 模型執行 → dbt-analytics-engineer(雖然 Airflow 可以觸發 dbt)| 串流處理 → streaming-pipeline-architect | 工作流程引擎(Temporal)→ distributed-transaction-manager

快速入門

  1. 定義 DAG — 使用 TaskFlow API(@dag、@task 裝飾器)建立 Python 原生 DAG
  2. 設定排程 — cron 或時間表,並設定 catchup=False,除非你有意執行回填
  3. 配置重試 — 在每個任務上設定 retries=2、retry_delay=timedelta(minutes=5)
  4. 新增 SLA — 在關鍵路徑任務上設定 sla=timedelta(hours=2)
  5. 本地測試 — 部署前執行 airflow dags test my_dag 2026-01-01

架構模式

TaskFlow API DAG

from airflow.decorators import dag, task
from datetime import datetime, timedelta

@dag(
    schedule="0 6 * * *",          # 每天早上 6 點 UTC
    start_date=datetime(2026, 1, 1),
    catchup=False,
    default_args={
        "retries": 2,
        "retry_delay": timedelta(minutes=5),
        "sla": timedelta(hours=2),
    },
    tags=["finance", "daily"],
)
def daily_revenue_pipeline():

    @task()
    def extract_payments() -> dict:
        """從 Stripe API 擷取資料"""
        data = stripe_client.list_payments(date=today())
        return {"count": len(data), "path": "s3://raw/payments/"}

    @task()
    def extract_orders() -> dict:
        """從 Shopify API 擷取資料"""
        data = shopify_client.list_orders(date=today())
        return {"count": len(data), "path": "s3://raw/orders/"}

    @task()
    def transform(payments: dict, orders: dict) -> str:
        """在 DuckDB 中進行連接與轉換"""
        result_path = run_duckdb_transform(payments["path"], orders["path"])
        return result_path

    @task()
    def load(path: str):
        """載入至 Snowflake"""
        snowflake_copy_into("fct_revenue", path)

    # 透過函數呼叫定義依賴
    payments = extract_payments()
    orders = extract_orders()
    transformed = transform(payments, orders)
    load(transformed)

daily_revenue_pipeline()

動態任務映射(扇出/扇入)

@task()
def get_partitions() -> list[str]:
    return ["2026-01-01", "2026-01-02", "2026-01-03"]

@task()
def process_partition(partition_date: str) -> dict:
    """為每個分割區並行執行"""
    return {"date": partition_date, "rows": process(partition_date)}

@task()
def aggregate(results: list[dict]):
    """扇入:接收所有分割區的結果"""
    total = sum(r["rows"] for r in results)
    log.info(f"處理了總共 {total} 行")

# 動態將 process_partition 映射到所有分割區
partitions = get_partitions()
results = process_partition.expand(partition_date=partitions)
aggregate(results)

dbt + Airflow 整合

from airflow.operators.bash import BashOperator
from cosmos import DbtDag, ProjectConfig, ProfileConfig

# 選項 1:cosmos(建議使用)
dbt_dag = DbtDag(
    project_config=ProjectConfig("/opt/airflow/dbt/"),
    profile_config=ProfileConfig(
        profile_name="default",
        target_name="prod",
    ),
    schedule="@daily",
    dag_id="dbt_daily",
)

# 選項 2:BashOperator(簡單)
dbt_run = BashOperator(
    task_id="dbt_run",
    bash_command="cd /opt/airflow/dbt && dbt build --select tag:daily",
)

反模式

  1. 肥大任務 — 任務應為原子單元;不要在同一個任務中執行擷取+轉換+載入
  2. 使用 XCom 傳輸大型資料 — XCom 僅用於元資料(路徑、計數);透過 S3/GCS 傳遞資料,不要使用 XCom pickle
  3. 意外啟用 catchup=True — 除非你想執行回填,否則請設定 catchup=False;否則 Airflow 會執行所有錯過的間隔
  4. 沒有重試 — 暫時性失敗很常見;務必設定 retries >= 1 並加上延遲
  5. DAG 檔案中的頂層程式碼 — DAG 檔案每 30 秒解析一次;模組層級的重型匯入或 API 呼叫會拖慢排程器

品質檢查清單

  • 使用 TaskFlow API 建立 Python 原生 DAG(而非傳統的運算子鏈結)
  • 除非有意回填,否則設定 catchup=False
  • 所有任務已配置重試(至少 1 次重試)
  • 關鍵路徑任務已設定 SLA
  • XCom 傳遞參考(S3 路徑),而非資料本體
  • 使用動態任務映射進行扇出並行處理
  • 部署前使用 airflow dags test 進行本地測試
  • 任務冪等性:重新執行任務會產生相同結果
  • 已配置任務失敗和 SLA 錯過的警報
  • 已套用 DAG 標籤以便在 Airflow UI 中過濾
