5. Common Pitfalls & How to Avoid Them

| Symptom | Root Cause | Remedy | |---------|------------|--------| | Load stalls at ~70 % | Destination log file is filling up because the recovery model is FULL and log backups are not occurring during the run. | Switch the target to BULK_LOGGED for the duration of the load or schedule a log‑backup every 10 min. | | “Deadlock victim” errors | Parallel writers are contending on a non‑clustered index that is being updated for each row. | Add a filtered index that excludes the load column, or temporarily drop the index and rebuild after the load. | | “Invalid column name” | Mismatch between source metadata and the destination table schema (e.g., a newly added column). | Refresh the Data Flow metadata or use the ValidateExternalMetadata = False property and map columns manually. | | Chunk size never grows | Destination table has a high page split rate; the engine keeps shrinking chunks to avoid log growth. | Re‑organize/re‑build the table’s clustered index before the load, or set a fixed ChunkSize if you know the optimal batch. | | High CPU usage on the SSIS host | MaxParallelism is set higher than the physical cores, causing context‑switch thrashing. | Set MaxParallelism ≤ Number of logical CPUs. | SSIS (SQL Server Integration Services) is a software

SSIS‑948 – “Smart‑Chunked Data Pump”

Overview
SSIS‑948 (often called the Smart‑Chunked Data Pump) is a built‑in, high‑performance data‑movement component introduced with SQL Server Integration Services 2019 CU4. It is designed to replace the classic OLE DB Destination / SQL Server Destination when loading very large fact tables, slowly‑changing‑dimension (SCD) tables, or any scenario where: slowly‑changing‑dimension (SCD) tables
