Your question is Refactoring Pipelines for Performance. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Can you describe your experience refactoring existing pipelines to improve performance? Discuss how you identified bottlenecks, selected changes across ingestion, transformation, storage, and orchestration, and validated that the refactored pipeline preserved correctness. Include your approach to benchmarking, incremental processing, idempotency, monitoring, rollback, and communicating trade-offs.
