Reviewer scorecard
“Software-defined assets are the right abstraction. Better DX than Airflow with type checking and built-in observability.”
“10-100x faster than pandas with better syntax. Lazy evaluation and parallel execution are game-changing for large datasets.”
“The asset-centric approach makes more sense than Airflow's task-centric model for modern data engineering.”
“The performance difference over pandas is not benchmarketing — it's real and measurable on any non-trivial dataset.”
“Dagster represents the next generation of data orchestration. Asset-based thinking replaces task-based thinking.”
“Polars is replacing pandas for performance-sensitive work. Rust-powered data tools are the future.”
