+# 台球场 ETL 系统
+
+用于台球门店业务的数据采集与入湖：从上游 API 拉取订单、支付、会员、库存等数据，先落地 ODS，再清洗写入事实/维度表，并提供运行追踪、增量游标、数据质量检查与测试脚手架。
+
+## 核心特性
+- **两阶段链路**：ODS 原始留痕 + DWD/事实表清洗，支持回放与重跑。
+- **任务注册与调度**：`TaskRegistry` 统一管理任务代码，`ETLScheduler` 负责游标、运行记录和失败隔离。
+- **统一底座**：配置（默认值 + `.env` + CLI 覆盖）、分页/重试的 API 客户端、批量 Upsert 的数据库封装、SCD2 维度处理、质量检查。
+- **测试与回放**：ONLINE/OFFLINE 模式切换，`run_tests.py`/`test_presets.py` 支持参数化测试；`MANUAL_INGEST` 可将归档 JSON 重灌入 ODS。
+- **可安装**：`setup.py` / `entry_point` 提供 `etl-billiards` 命令，或直接 `python -m cli.main` 运行。
+
+## 仓库结构（摘录）
+- `etl_billiards/config`：默认配置、环境变量解析、配置加载。
+- `etl_billiards/api`：HTTP 客户端，内置重试/分页。
+- `etl_billiards/database`：连接管理、批量 Upsert。
+- `etl_billiards/tasks`：业务任务（ORDERS、PAYMENTS…）、ODS 任务、DWD 任务、人工回放；`base_task.py`/`base_dwd_task.py` 提供模板。
+- `etl_billiards/loaders`：事实/维度/ODS Loader；`scd/` 为 SCD2。
+- `etl_billiards/orchestration`：调度器、任务注册表、游标与运行追踪。
+- `etl_billiards/scripts`：测试执行器、数据库连通性检测、预置测试指令。
+- `etl_billiards/tests`：单元/集成测试与离线 JSON 归档。
+
+## 支持的任务代码
+- **事实/维度**：`ORDERS`、`PAYMENTS`、`REFUNDS`、`INVENTORY_CHANGE`、`COUPON_USAGE`、`MEMBERS`、`ASSISTANTS`、`PRODUCTS`、`TABLES`、`PACKAGES_DEF`、`TOPUPS`、`TABLE_DISCOUNT`、`ASSISTANT_ABOLISH`、`LEDGER`、`TICKET_DWD`、`PAYMENTS_DWD`、`MEMBERS_DWD`。
+- **ODS 原始采集**：`ODS_ORDER_SETTLE`、`ODS_TABLE_USE`、`ODS_ASSISTANT_LEDGER`、`ODS_ASSISTANT_ABOLISH`、`ODS_GOODS_LEDGER`、`ODS_PAYMENT`、`ODS_REFUND`、`ODS_COUPON_VERIFY`、`ODS_MEMBER`、`ODS_MEMBER_CARD`、`ODS_PACKAGE`、`ODS_INVENTORY_STOCK`、`ODS_INVENTORY_CHANGE`。
+- **辅助**：`MANUAL_INGEST`（将归档 JSON 回放到 ODS）。
+
+## 快速开始
+1. **环境要求**：Python 3.10+、PostgreSQL。推荐在 `etl_billiards/` 目录下执行命令。
+2. **安装依赖**
+   ```bash
+   cd etl_billiards
+   pip install -r requirements.txt
+   # 开发模式：pip install -e .
+   ```
+3. **配置 `.env`**
+   ```bash
+   cp .env.example .env
+   # 核心项
+   PG_DSN=postgresql://user:pwd@host:5432/LLZQ
+   API_BASE=https://api.example.com
+   API_TOKEN=your_token
+   STORE_ID=2790685415443269
+   EXPORT_ROOT=/path/to/export
+   LOG_ROOT=/path/to/logs
+   ```
+   配置的生效顺序为 “默认值” < “环境变量/.env” < “CLI 参数”。
+4. **运行任务**
+   ```bash
+   # 运行默认任务集
+   python -m cli.main
+
+   # 按需选择任务（逗号分隔）
+   python -m cli.main --tasks ODS_ORDER_SETTLE,ORDERS,PAYMENTS
+
+   # Dry-run 示例（不提交事务）
+   python -m cli.main --tasks ORDERS --dry-run
+
+   # Windows 批处理
+   ..\\run_etl.bat --tasks PAYMENTS
+   ```
+5. **查看输出**：日志目录与导出目录分别由 `LOG_ROOT`、`EXPORT_ROOT` 控制；运行追踪与游标记录写入数据库 `etl_admin.*` 表。
+
+## 数据与运行流转
+- CLI 解析参数 → `AppConfig.load()` 组装配置 → `ETLScheduler` 创建 DB/API/游标/运行追踪器。
+- 调度器按任务代码实例化任务，读取/推进游标，落盘运行记录。
+- 任务模板：确定时间窗口 → 调用 API/ODS 数据 → 解析校验 → Loader 批量 Upsert/SCD2 → 质量检查 → 提交事务并回写游标。
+
+## 测试与回放
+- 单元/集成测试：`pytest` 或 `python scripts/run_tests.py --suite online`。
+- 预置组合：`python scripts/run_tests.py --preset offline_realdb`（见 `scripts/test_presets.py`）。
+- 离线模式：`TEST_MODE=OFFLINE TEST_JSON_ARCHIVE_DIR=... pytest tests/unit/test_etl_tasks_offline.py`。
+- 数据库连通性：`python scripts/test_db_connection.py --dsn postgresql://... --query "SELECT 1"`。
+
+## 其他提示
+- `.env.example` 列出了所有常用配置；`config/defaults.py` 记录默认值与任务窗口配置。
+- `loaders/ods/generic.py` 支持定义主键/列名即可落 ODS；`tasks/manual_ingest_task.py` 可将归档 JSON 快速灌入对应 ODS 表。
+- 需要新增任务时，在 `tasks/` 中实现并在 `orchestration/task_registry.py` 注册即可复用调度能力。

+#### 3.3.1 测试模式（ONLINE / OFFLINE）
+
+- `TEST_MODE=ONLINE`（默认）时，测试会模拟实时 API，完整执行 E/T/L。
+- `TEST_MODE=OFFLINE` 时，测试改为从 `TEST_JSON_ARCHIVE_DIR` 指定的归档 JSON 中读取数据，仅做 Transform + Load，适合验证本地归档数据是否仍可回放。
+- `TEST_JSON_ARCHIVE_DIR`：离线 JSON 归档目录（示例：`tests/source-data-doc` 或 CI 产出的快照）。
+- `TEST_JSON_TEMP_DIR`：测试生成的临时 JSON 输出目录，便于隔离每次运行的数据。
+- `TEST_DB_DSN`：可选，若设置则单元测试会连接到此 PostgreSQL DSN，实打实执行写库；留空时测试使用内存伪库，避免依赖数据库。
+
+示例命令：
+
+```bash
+# 在线模式覆盖所有任务
+TEST_MODE=ONLINE pytest tests/unit/test_etl_tasks_online.py
+
+# 离线模式使用归档 JSON 覆盖所有任务
+TEST_MODE=OFFLINE TEST_JSON_ARCHIVE_DIR=tests/source-data-doc pytest tests/unit/test_etl_tasks_offline.py
+
+# 使用脚本按需组合参数（示例：在线 + 仅订单用例）
+python scripts/run_tests.py --suite online --mode ONLINE --keyword ORDERS
+
+# 使用脚本连接真实测试库并回放离线模式
+python scripts/run_tests.py --suite offline --mode OFFLINE --db-dsn postgresql://user:pwd@localhost:5432/testdb
+
+# 使用“指令仓库”中的预置命令
+python scripts/run_tests.py --preset offline_realdb
+python scripts/run_tests.py --list-presets   # 查看或自定义 scripts/test_presets.py
+```
+
+#### 3.3.2 脚本化测试组合（`run_tests.py` / `test_presets.py`）
+
+- `scripts/run_tests.py` 是 pytest 的统一入口：自动把项目根目录加入 `sys.path`，并提供 `--suite online/offline/integration`、`--tests`（自定义路径）、`--mode`、`--db-dsn`、`--json-archive`、`--json-temp`、`--keyword/-k`、`--pytest-args`、`--env KEY=VALUE` 等参数，可以像搭积木一样自由组合；
+- `--preset foo` 会读取 `scripts/test_presets.py` 内 `PRESETS["foo"]` 的配置，并叠加到当前命令；`--list-presets` 与 `--dry-run` 可用来审阅或仅打印命令；
+- 直接执行 `python scripts/test_presets.py` 可依次运行 `AUTO_RUN_PRESETS` 中列出的预置；传入 `--preset x --dry-run` 则只打印对应命令。
+
+`test_presets.py` 充当“指令仓库”。每个预置都是一个字典，常用字段解释如下：
+
+| 字段                         | 作用                                                               |
+| ---------------------------- | ------------------------------------------------------------------ |
+| `suite`                      | 复用 `run_tests.py` 内置套件（online/offline/integration，可多选） |
+| `tests`                      | 追加任意 pytest 路径，例如 `tests/unit/test_config.py`             |
+| `mode`                       | 覆盖 `TEST_MODE`（ONLINE / OFFLINE）                               |
+| `db_dsn`                     | 覆盖 `TEST_DB_DSN`，用于连入真实测试库                             |
+| `json_archive` / `json_temp` | 配置离线 JSON 归档与临时目录                                       |
+| `keyword`                    | 映射到 `pytest -k`，用于关键字过滤                                 |
+| `pytest_args`                | 附加 pytest 参数，例 `-vv --maxfail=1`                             |
+| `env`                        | 额外环境变量列表，如 `["STORE_ID=123"]`                            |
+| `preset_meta`                | 说明性文字，便于描述场景                                           |
+
+示例：`offline_realdb` 预置会设置 `TEST_MODE=OFFLINE`、指定 `tests/source-data-doc` 为归档目录，并通过 `db_dsn` 连到测试库。执行 `python scripts/run_tests.py --preset offline_realdb` 或 `python scripts/test_presets.py --preset offline_realdb` 即可复用该组合，保证本地、CI 与生产回放脚本一致。
+
+#### 3.3.3 数据库连通性快速检查
+
+`python scripts/test_db_connection.py` 提供最轻量的 PostgreSQL 连通性检测：默认使用 `TEST_DB_DSN`（也可传 `--dsn`），尝试连接并执行 `SELECT 1 AS ok`（可通过 `--query` 自定义）。典型用途：
+
+```bash
+# 读取 .env/环境变量中的 TEST_DB_DSN
+python scripts/test_db_connection.py
+
+# 临时指定 DSN，并检查任务配置表
+python scripts/test_db_connection.py --dsn postgresql://user:pwd@host:5432/.... --query "SELECT count(*) FROM etl_admin.etl_task"
+```
+
+脚本返回 0 代表连接与查询成功；若返回非 0，可结合第 8 章“常见问题排查”的数据库章节（网络、防火墙、账号权限等）先定位问题，再运行完整 ETL。

+### 5.6 ODS + DWD 双阶段策略（新增）
+
+为了支撑回溯/重放与后续 DWD 宽表构建，项目新增了 `billiards_ods` Schema 以及一组专门的 ODS 任务/Loader：
+
+- **ODS 表**：`billiards_ods.ods_order_settle`、`ods_table_use_detail`、`ods_assistant_ledger`、`ods_assistant_abolish`、`ods_goods_ledger`、`ods_payment`、`ods_refund`、`ods_coupon_verify`、`ods_member`、`ods_member_card`、`ods_package_coupon`、`ods_inventory_stock`、`ods_inventory_change`。每条记录都会保存 `store_id + 源主键 + payload JSON + fetched_at + source_endpoint` 等信息。
+- **通用 Loader**：`loaders/ods/generic.py::GenericODSLoader` 统一封装了 `INSERT ... ON CONFLICT ...` 与批量写入逻辑，调用方只需提供列名与主键列即可。
+- **ODS 任务**：`tasks/ods_tasks.py` 内通过 `OdsTaskSpec` 定义了一组任务（`ODS_ORDER_SETTLE`、`ODS_PAYMENT`、`ODS_ASSISTANT_LEDGER` 等），并在 `TaskRegistry` 中自动注册，可直接通过 `python -m cli.main --tasks ODS_ORDER_SETTLE,ODS_PAYMENT` 执行。
+- **双阶段链路**：
+  1. 阶段 1（ODS）：调用 API/离线归档 JSON，将原始记录写入 ODS 表，保留分页、抓取时间、来源文件等元数据。
+  2. 阶段 2（DWD/DIM）：后续订单、支付、券等事实任务将改为从 ODS 读取 payload，经过解析/校验后写入 `billiards.fact_*`、`dim_*` 表，避免重复拉取上游接口。
+
+> 新增的单元测试 `tests/unit/test_ods_tasks.py` 覆盖了 `ODS_ORDER_SETTLE`、`ODS_PAYMENT` 的入库路径，可作为扩展其他 ODS 任务的模板。

+
+## 11. 运行/调试模式说明
+
+- 生产环境仅保留“任务模式”：通过调度/CLI 执行注册的任务（ETL/ODS），不使用调试脚本。
+- 开发/调试可使用的辅助脚本（上线前可删除或禁用）：
+  - `python -m etl_billiards.scripts.rebuild_ods_from_json`：从本地 JSON 目录重建 `billiards_ods`，用于离线初始化/验证。环境变量：`PG_DSN`（必填）、`JSON_DOC_DIR`（可选，默认 `C:\dev\LLTQ\export\test-json-doc`）、`INCLUDE_FILES`（逗号分隔文件名）、`DROP_SCHEMA_FIRST`（默认 true）。
+- 如需在生产环境保留脚本，请在运维手册中明确用途和禁用条件，避免误用。
+
+## 12. ODS 任务上线指引
+
+- 任务注册：`etl_billiards/database/seed_ods_tasks.sql` 列出了当前启用的 ODS 任务。将其中的 `store_id` 替换为实际门店后执行：
+  ```
+  psql "$PG_DSN" -f etl_billiards/database/seed_ods_tasks.sql
+  ```
+  `ON CONFLICT` 会保持 enabled=true，避免重复。
+- 调度：确认 `etl_admin.etl_task` 中已启用所需的 ODS 任务（任务代码见 seed 脚本），调度器或 CLI `--tasks` 即可调用。
+- 离线回灌：开发环境可用 `rebuild_ods_from_json` 以样例 JSON 初始化 ODS，生产慎用；默认按 `(source_file, record_index)` 去重。
+- 测试：`pytest etl_billiards/tests/unit/test_ods_tasks.py` 覆盖核心 ODS 任务；测试时可设置 `ETL_SKIP_DOTENV=1` 跳过本地 .env 读取。

+  - `ODS_INCLUDE_FILES`：限定导入的文件名（逗号分隔，不含 .json）
+  - `ODS_DROP_SCHEMA_FIRST`：true/false，是否重建 schema
+  - `ETL_SKIP_DOTENV`：测试/CI 时设为 1 跳过本地 .env 读取
+- `config/defaults.py` 中 `ods` 默认值：
+  - `json_doc_dir`: `C:\dev\LLTQ\export\test-json-doc`
+  - `include_files`: `""`
+  - `drop_schema_first`: `True`
+
+---
+
+## 15. DWD 维度 “业务事件”
+
+1. 粒度唯一、原子
+
+- 一张 DWD 表只能有一种业务粒度，比如：
+  - 一条记录 = 一次结账；
+  - 一条记录 = 一段台费流水；
+  - 一条记录 = 一次助教服务；
+  - 一条记录 = 一次会员余额变动。
+- 表里面不能又混“订单头”又混“订单行”，不能一部分是“汇总”，一部分是“明细”。
+- 一旦粒度确定，所有字段都要跟这个粒度匹配：
+  - 比如“结账头表”就不要塞每一行商品明细；
+  - 商品明细就不要塞整单级别的总金额。
+  - 这是 DWD 层最重要的一条。
+
+2. 以业务过程建模，不以 JSON 列表建模
+
+- 先画清楚你真实的业务链路：
+  - 开台 / 换台 / 关台 → 台费流水
+  - 助教上桌 → 助教服务流水 / 废除事件
+  - 点单 → 商品销售流水
+  - 充值 / 消费 → 余额变更 / 充值单
+  - 结账 → 结账头表 + 支付流水 / 退款流水
+  - 团购 / 平台券 → 核销流水
+
+3. 主键明确、外键统一
+
+- 每张 DWD 表必须有业务主键（哪怕是接口给的 id），不要依赖数据库自增。
+- 所有“同一概念”的字段必须统一命名、统一含义：
+  - 门店：统一叫 site_id，都对应 siteProfile.id；
+  - 会员：统一叫 member_id 对应 member_profiles.id，system_member_id 单独一列；
+  - 台桌：统一 table_id 对应 site_tables_master.id；
+  - 结账：统一 order_settle_id；
+  - 订单：统一 order_trade_no 等。
+- 否则后面 DWS、AI 要把表拼起来会非常痛苦。
+
+4. 保留明细，不做过度汇总
+
+- DWD 层的事实表原则上只做“明细级”的数据：
+  - 不要在 DWD 就把“日汇总、周汇总、月汇总”算出来，那是 DWS 的事；
+  - 也不要把多个事件折成一行（例如一张表同时放日汇总+单笔流水）。
+- 需要聚合时，再在 DWS 做主题宽表：
+  - dws_member_day_profile、dws_site_day_summary 等。
+- DWD 只负责细颗粒度的真相。
+
+5. 统一清洗、标准化，但保持可追溯
+
+- 在 DWD 层一定要做的清洗：
+  - 类型转换：字符串时间 → 时间类型，金额统一为 decimal，布尔统一为 0/1；
+  - 单位统一：秒 / 分钟、元 / 分都统一；
+  - 枚举标准化：状态码、类型码在 DWD 里就定死含义，必要时建枚举维表。
+- 同时要保证：
+  - 每条 DWD 记录都能追溯回 ODS：
+- 保留源系统主键；
+  - 保留原始时间 / 原始金额字段（不要覆盖掉）。
+
+6. 扁平化、去嵌套
+
+- JSON 里常见结构是：分页壳 + 头 + 明细数组 + 各种嵌套对象（siteProfile、tableProfile、goodsLedgers…）。
+- DWD 的原则是：
+  - 去掉分页壳；
+  - 把“数组”拆成子表（头表 / 行表）；
+  - 把重复出现的 profile 抽出去做维度表（门店、台、商品、会员……）。
+- 目标是：DWD 表都是二维表结构，不存复杂嵌套 JSON。
+
+7. 模型长期稳定，可扩展
+
+- DWD 的表结构要尽可能稳定，新增需求尽量通过：
+  - 加字段；
+  - 新建事实表 / 维度表；
+  - 在 DWS 做派生指标；
+  - 而不是频繁重构已有 DWD 表结构。
+- 这点跟你后面要喂给 LLM 也很相关：AI 配的 prompt、schema 理解都要尽量少改。
