Here is a summary: --- ## TASK 1: Execute Dataflow Structure Analysis (Two Phases) **STATUS**: done **USER QUERIES**: Initial request (from context transfer) **DETAILS**: Completed in previous conversation. Ran `analyze_dataflow.py` and `gen_dataflow_report.py`. Output at `export/SYSTEM/REPORTS/dataflow_analysis/`. **FILEPATHS**: `scripts/ops/analyze_dataflow.py`, `scripts/ops/gen_dataflow_report.py` ## TASK 2: Investigate Two Missing Field Mappings **STATUS**: done **USER QUERIES**: From context transfer + user follow-up asking to scan JSON values **DETAILS**: - `time_slot_sale` (store_goods_master): API returns it (all values = `'2'`, 692 records across 4 batches), but ODS DDL never had it - `commoditycode` (tenant_goods_master): API JSON does NOT return `commoditycode` field (696 records all missing). API returns `commodity_code` instead (single string values like `'10000'`, `'10000028'`). All values are single-element (no multi-value arrays found). ODS has both `commodityCode TEXT` and `commodity_code TEXT` columns. - One-off scan script `_scan_json_fields.py` was created and deleted - JSON structure: `pages[].response.data.orderGoodsList` for store_goods, `pages[].response.data.tenantGoodsList` for tenant_goods **FILEPATHS**: `scripts/ops/_scan_json_fields.py` (deleted) ## TASK 3: Add time_slot_sale + Merge commodity_code (Task 1 from user) **STATUS**: in-progress **USER QUERIES**: User's main request with two sub-tasks **DETAILS**: What was completed: 1. **Migration script created and executed on test DB** — all 3 ALTER TABLE operations succeeded: - `ods.store_goods_master` ADD `time_slot_sale INTEGER` ✓ - `dwd.dim_store_goods_ex` ADD `time_slot_sale INTEGER` ✓ - `dwd.dim_tenant_goods_ex.commodity_code_list` changed from `VARCHAR(256)` to `TEXT[]` ✓ - Verification confirmed: ODS time_slot_sale=integer, DWD time_slot_sale=integer, commodity_code_list=ARRAY/_text 2. **DDL files updated**: - `db/etl_feiqiu/schemas/ods.sql`: Added `time_slot_sale INTEGER` to store_goods_master + COMMENT ✓ - `db/etl_feiqiu/schemas/dwd.sql`: Added `time_slot_sale INTEGER` to dim_store_goods_ex + COMMENT ✓ - `db/etl_feiqiu/schemas/dwd.sql`: Changed `commodity_code_list VARCHAR(256)` → `TEXT[]` ✓ 3. **FACT_MAPPINGS updated** (partially): - `dwd.dim_store_goods_ex`: Added `("time_slot_sale", "time_slot_sale", None)` ✓ - **NOT YET DONE**: `dwd.dim_tenant_goods_ex` commodity_code_list mapping needs update — currently maps from `commodity_code` (single value) but needs to map from `"commodityCode"` (the ODS column that stores the array format `["10000028"]`) and cast to TEXT[] 4. **Migration script file**: `db/etl_feiqiu/migrations/2026-02-21__add_time_slot_sale_merge_commodity_code.sql` ✓ 5. **One-off migration runner**: `scripts/ops/_run_migration.py` still exists (needs cleanup) **NEXT STEPS** (Task 1 remaining): - Update FACT_MAPPINGS for `dwd.dim_tenant_goods_ex` — the `commodity_code_list` mapping currently reads `("commodity_code_list", "commodity_code", None)` but needs to be changed to map from `"commodityCode"` column and parse the JSON array `["10000028"]` into a PostgreSQL TEXT[] array. The mapping expression needs a cast like `"string_to_array(trim(both '[]' from \"commodityCode\"), ',')"` or similar approach using the ODS `commodityCode` column which stores `{10000028}` format - The ODS loader is schema-aware (`_insert_records_schema_aware` in `ods_tasks.py` line 721) — it dynamically reads columns from DB, so no code change needed for ODS ingestion - Clean up `scripts/ops/_run_migration.py` - Update `docs/database/` with schema change documentation (db-docs.md rule) - The `gen_field_review_doc.py` skip lists may need updating (lines ~908 and ~634) to reflect these fields are now mapped **FILEPATHS**: - `db/etl_feiqiu/migrations/2026-02-21__add_time_slot_sale_merge_commodity_code.sql` - `db/etl_feiqiu/schemas/ods.sql` - `db/etl_feiqiu/schemas/dwd.sql` - `apps/etl/connectors/feiqiu/tasks/dwd/dwd_load_task.py` (FACT_MAPPINGS at ~line 113) - `scripts/ops/_run_migration.py` (to delete) ## TASK 4: DDL vs Database Consistency Check + Migration Archive (Task 2 from user) **STATUS**: not-started **USER QUERIES**: User's second sub-task: "做完任务1后，检查主DDL+种子等，包含ODS DWD DWS INDEX。是否与当前数据库相同，若有遗失和偏差则合并，检查好后，将分支后续修改的DDL归档。" **DETAILS**: Compare all DDL files (ODS, DWD, DWS, indexes) against actual test database schema. Find discrepancies, merge missing definitions, then archive branch migration scripts. **NEXT STEPS**: - Write a script to compare DDL files vs actual DB columns for all schemas (ods, dwd, dws) - Check indexes match - Check seeds - Merge any discrepancies - Archive migration scripts from this branch **FILEPATHS**: `db/etl_feiqiu/schemas/ods.sql`, `db/etl_feiqiu/schemas/dwd.sql`, `db/etl_feiqiu/schemas/dws.sql`, `db/etl_feiqiu/schemas/` (index files), `db/etl_feiqiu/seeds/`, `db/etl_feiqiu/migrations/` ## USER CORRECTIONS AND INSTRUCTIONS: - All output must go to `export/` directory structure via `.env` environment variables - Scripts run from `scripts/ops/` — but cwd is currently stuck at `scripts/ops/` in the shell, so use absolute paths like `python C:\NeoZQYY\scripts\ops\script.py` - Database testing uses `TEST_DB_DSN` (test_etl_feiqiu), never production - All explanatory text in simplified Chinese - Python scripts preferred over PowerShell for complex operations - ODS loader is schema-aware — reads columns from DB dynamically, no hardcoded column lists needed - Audit reminder is pending (root-file, dir:admin-web, dir:backend, dir:db, db-schema-change) — user will manually trigger `/audit` - `db-docs.md` rule: any schema change must sync `docs/database/` with change description, compatibility notes, rollback strategy, and 3+ verification SQLs - The locked `field_mappings/` directory in `export/SYSTEM/REPORTS/dataflow_analysis/` should be manually deleted after system restart (from previous task) ## Key Architecture Notes: - ODS tables use `(id, content_hash)` as composite PK - DWD dimension tables use SCD2 with `(pk, scd2_start_time)` as composite PK - FACT_MAPPINGS in `dwd_load_task.py` format: `(dwd_column, ods_expression, cast_type)` - ODS ingestion: `BaseOdsTask._insert_records_schema_aware()` dynamically reads table columns from DB — adding a column to DDL+DB is sufficient for ODS to start capturing it - DWD loading: columns not in FACT_MAPPINGS are auto-mapped by matching column names between ODS and DWD ## Files to read - `apps/etl/connectors/feiqiu/tasks/dwd/dwd_load_task.py` (FACT_MAPPINGS — need to fix commodity_code_list mapping) - `db/etl_feiqiu/schemas/dwd.sql` (recently modified) - `db/etl_feiqiu/schemas/ods.sql` (recently modified) - `db/etl_feiqiu/migrations/2026-02-21__add_time_slot_sale_merge_commodity_code.sql` - `scripts/ops/_run_migration.py` (needs cleanup) - `scripts/ops/gen_field_review_doc.py` (skip lists may need updating) USER QUERIES(most recent first): 1. 任务1：time_slot_sale 在ODS和DWD中添加。commoditycode 和 commodity_code 合并。采用数组方式吧。入库，落地，做好DDL，MAPPING等处理，文档落地等工作任务2：做完任务1后，检查主DDL+种子等，包含ODS DWD DWS INDEX。是否与当前数据库相同，若有遗失和偏差则合并，检查好后，将分支后续修改的DDL归档。 2.
