| ✅ | Practice | Reason | |----|----------|--------| | 1 | Parameter‑first design – keep hard‑coded literals to a minimum. | Simplifies promotion across environments. | | 2 | Use Set‑Based SCD Logic (MERGE) instead of the wizard. | Far better performance for large dimensions. | | 3 | Enable Data Flow logging at Detailed level in SSISDB. | Gives you row‑counts and helps pinpoint bottlenecks. | | 4 | Chunk large files (if > 5 GB) with a Batch Size property on the Flat File Source. | Reduces memory pressure on the data‑flow engine. | | 5 | Avoid blocking transformations (e.g., Sort, Aggregate) unless absolutely necessary. | They force the engine to spill to disk. | | 6 | Set MaxErrorCount to a sensible value (e.g., 50) for the Data Flow. | Prevents a single bad row from aborting the whole run. | | 7 | **Leverage the SSIS Catalog’s built‑in Stored Procedures (catalog.start_execution, catalog.stop_execution) for programmatic runs. | Enables CI/CD pipelines to trigger packages reliably. | | 8 | Encrypt sensitive parameters (e.g., Azure SAS tokens) using the SSISDB encryption feature. | Protects credentials at rest. | | 9 | Document package flow with Annotations and Data Flow Path Descriptions. | Improves maintainability for future developers. | |10| Version‑control the .ispac and keep a CHANGELOG.md alongside. | Guarantees traceability of package evolution. |

When a file like "SSIS-951.mp4" exists, it is usually the end product of a complex digital lifecycle: SSIS-951.mp4

The SCD dimension in the demo is Dim_Account. Instead of using the built‑in SCD Wizard, the video walks through a hand‑crafted approach: | ✅ | Practice | Reason | |----|----------|--------|

  • Execute SQL Task – Performs a MERGE:

    • MERGE INTO dbo.Dim_Account AS tgt
USING #TempSCD AS src
ON tgt.AccountKey = src.AccountKey AND tgt.IsCurrent = 1
WHEN MATCHED AND src.IsChanged = 1 THEN
    UPDATE SET 
        tgt.IsCurrent = 0,
        tgt.EndDate   = @LoadDate
WHEN NOT MATCHED BY TARGET THEN
    INSERT (AccountKey, AccountName, ..., IsCurrent, StartDate, EndDate)
    VALUES (src.AccountKey, src.AccountName, ..., 1, @LoadDate, '9999-12-31');

    Why avoid the wizard?
    The wizard hides the set‑based logic and can generate row‑by‑row INSERT/UPDATE statements that become a performance bottleneck on large dimensions (> 1 M rows). The manual MERGE approach is scalable, transparent, and easily version‑controlled. When a file like "SSIS-951
