Bodo DataFrames vs PySpark and Dask on TPC-H Benchmarks
Blog post from Bodo
Bodo DataFrames demonstrates superior performance and minimal migration effort for large-scale analytical tasks compared to other dataframe systems like PySpark and Dask, as evidenced by the TPC-H benchmark results. The benchmark, which tests complex joins, aggregations, and filtering across extensive datasets, shows Bodo completing all 22 queries in 930 seconds, significantly faster than PySpark's 5,000 seconds and Dask's 114,000 seconds. Bodo's advantage lies in its ability to execute standard Pandas-based code without modification, utilizing a cost-based relational optimizer and a C++ streaming backend that reduces memory pressure and optimizes data movement. In contrast, PySpark, while capable of handling massive workloads, requires extensive code rewrites and suffers from performance overheads due to JVM-Python interoperability and intermediate materialization. Dask retains the familiar Pandas API but lacks the optimization needed for complex multi-table queries, resulting in substantial performance drawbacks. Bodo emerges as the most efficient solution for teams seeking to scale Pandas applications without the cost and complexity of a full system refactor, offering high-performance analytics directly compatible with existing workflows.
