Ssis-834 =link= Jun 2026

Yua Mikami, a former member of the idol group SKE48, transitioned to the adult industry in 2015 and quickly became a global sensation. After an eight-year career, she announced her retirement to focus on other ventures, including her fashion brand and mainstream entertainment roles. SSIS-834 was produced as the culmination of her career, often referred to by fans and retailers as the "Complete Retirement" or "Last Day" film. Key Details and Production

| Field | Value | |-------|-------| | | SSIS‑834 | | Created by | Product Owner | | Created on | 2026‑04‑10 | | Priority | High | | Epic | Data Warehouse Refresh (Q2 2026) | | Component | SSIS Package – DW_Load_SalesFact.dtsx | | Status | New (Backlog) |

| # | Criteria | |---|----------| | | The package runs in < 30 minutes on a typical production night (average 200 k new/updated rows). | | AC‑2 | Only rows with TransactionDate > LastLoadTimestamp OR rows where HashCheck differs from the target are transferred. | | AC‑3 | A control table ( dbo.ETL_LoadLog ) is updated atomically with: • PackageName = DW_Load_SalesFact • RunStart , RunEnd timestamps • RowsInserted , RowsUpdated counts • Status (Success / Failed) | | AC‑4 | In case of failure, the package rolls back any partially loaded data and writes the error details to dbo.ETL_ErrorLog . | | AC‑5 | The package maintains idempotency – re‑running a failed load with the same LastLoadTimestamp does not duplicate rows. | | AC‑6 | All new/updated rows are validated against the target schema (data‑type, NOT NULL, FK checks) before commit. | | AC‑7 | Documentation (README, data‑lineage diagram) is updated to reflect the new incremental logic. | | AC‑8 | Unit tests (C# / SQL) cover: • detection of new rows • detection of changed rows via HashCheck • correct handling of no‑change scenario • error‑path handling (e.g., source table unavailable). | ssis-834

Add Incremental Load Logic to the Sales Fact Data Flow (SSIS)

Data Warehouse Engineer, I want the DW_Load_SalesFact SSIS package to process only new and changed rows from the source dbo.Sales_Transactions table (incremental load), so that the nightly ETL finishes within the 30‑minute window, reduces source‑to‑target latency, and avoids unnecessary data movement.

| Step | Action | |------|--------| | 1 | Verify DW_Load_SalesFact last successful run timestamp in ETL_LoadLog . | | 2 | Trigger the package via Job_DW_Load_SalesFact . | | 3 | Monitor SSISDB catalog.operation_messages for Error level messages. | | 4 | After completion, query ETL_LoadLog to confirm RowsInserted + RowsUpdated > 0. | | 5 | Run a quick row‑count check on the target fact table to ensure total rows = previous total + inserted – (if any deletes). | | 6 | If any failure, review ETL_ErrorLog , fix root cause, and re‑run the job (no duplicate rows should be created). | | 7 | Update the Operations Dashboard with the run status and performance metrics. |

| Risk | Likelihood | Impact | Mitigation | |------|------------|--------|------------| | : Source HashCheck missing or not deterministic (e.g., floating‑point columns). | Medium | High (wrong change detection) | Validate hash algorithm on a sample set; if needed, create a surrogate hash using CONVERT(VARBINARY, ...) and rounding. | | R‑2 : Lookup cache overflow for very large target ( > 2 GB). | Low | Medium | Use Partial Cache with a query that filters on recent dates ( TransactionDate > @LastLoadTimestamp ). | | R‑3 : Package fails mid‑load and leaves the target in an inconsistent state. | Low | High | Enforce Package TransactionOption = Required and test rollback paths. | | R‑4 : Time‑zone drift between source and ETL server causing missed rows. | Low | Medium | Store all timestamps in UTC; convert in the package using GETUTCDATE() . | | R‑5 : Performance regression on the UPDATE path (slow OLE DB Command). | Medium | Medium | If UPDATE volume grows, switch to staging table + MERGE statement executed via Execute SQL Task. | Key Details and Production | Field | Value
