Optimize a Large Data Workflow

A large pipeline already produces correct outputs, but runtime and cost are too high. You need to improve efficiency without changing business logic, output definitions, or downstream expectations.

Problem

What This Tests

ETL optimization techniques
Batch workflow tuning
Orchestration-aware improvements
Data quality preservation during optimization
Tool-specific performance trade-offs in Alteryx Designer Cloud and Snowflake

Constraints

Do not change business logic

Do not change final output schema

Keep existing data quality expectations

Prefer operationally simple improvements first
