| Area | Recommendation | Typical Impact |
|------|----------------|----------------|
| Batch Size | Set FastLoadOptions = "TABLOCK, CHECK_CONSTRAINTS" and MaximumInsertCommitSize = 0 (full batch). If you hit transaction log pressure, set to 50000 rows. |
| Parallelism | Split the source data into N partitions using a hash on the business key. Deploy N parallel Data Flow Tasks feeding the same staging table (use MERGE after all partitions have completed). |
| Indexes | Keep no non‑clustered indexes on the staging table while loading. Add them after the load if downstream queries need them. |
| TempDB | Ensure TempDB is on fast SSDs and sized to accommodate the bulk‑load transaction log. |
| Memory | In the SSIS runtime configuration (dtsconfig), set DefaultBufferMaxRows (e.g., 10,000) and DefaultBufferSize (e.g., 10 MB) based on column width. |
| Statistics | Run SET STATISTICS IO, TIME ON; on the MERGE script in a dev environment

| Item | Description |
|------|-------------|
| Name | SSIS‑668 – a reference implementation for incremental, change‑data‑capture (CDC) loading of master data from an operational source (OLTP) into a dimensional / reporting data‑warehouse. |
| Core Features | • Detects inserts, updates, deletes (SCD‑2) using source CDC tables or timestamp columns
• Handles high‑volume data (hundreds of millions rows per run)
• Supports parallelism via partitioned data flows
• Provides idempotent loads – safe to re‑run without duplication
• Emits detailed audit logs (run‑time, row‑counts, error files) |
| Typical Use Cases | • Nightly master‑data sync from ERP to DW
• Near‑real‑time CDC pipelines (via SSIS + SQL Server Agent)
• Data‑warehouse staging area refreshes |
| Why It Has a “668” Tag | The original internal ticket/feature request was #668. Over time the name stuck as the de‑facto reference pattern. It is now shared across multiple projects, so the tag is used for documentation, versioning, and support tickets. |
Note: If your organization uses a different definition (e.g., a custom package named “SSIS‑668”), map the concepts below to your local naming conventions. | Area | Recommendation | Typical Impact |
