Strategies: (1) ForEach batchCount >1 (max 20). (2) Copy Data parallelCopies (up to 256 cloud). (3) Multiple pipelines concurrently. (4) Data Flow partition tuning. (5) SHIR multiple nodes. Trade-off: Source/sink limits; throttling. Best practice: Balance parallelism with limits; monitor IR and activity metrics.

The complete answer continues with detailed implementation patterns, architectural trade-offs, and production-grade considerations covering performance optimization and real-world examples.
