Spark, Dask, DuckDB, Polars: Benchmarks at Scale

Matthew Rocklin Matthew Rocklin | CEO | Coiled

Large scale data analysis has blown up recently, and standard ad-hoc analysis tools like Apache Spark and Pandas are joined by new friends. In this talk we benchmark four popular large-data dataframe/database tools for large scale analysis Spark, Dask, DuckDB, and Polars on the popular TPC-H benchmark suite. We do this both on single machines and on the cloud at scales ranging from 10GB to 10TB.

No tool wins consistently, but by looking at detailed performance metrics we can better understand the technical nuance and challenges in this space, and guide projects towards better performance.
