**Architectural logic**: 1TB is large enough that naive single-threaded copy will miss SLAs; parallelism and staging are critical. **Why parallel copy**: ADF's Copy activity supports parallelCopies (default 1, max ~32 on Azure IR)—each copy runs concurrently, bounded by source/sink throughput and IR capacity. For databases, use physical partition option so ADF splits by partition key. For file-based (S3/Blob), use wildcard paths and binary copy to avoid schema parsing....
