Top 5 C++ Dataframe Projects

cudf

23 7,274 9.9 C++

cuDF - GPU DataFrame Library

Project mention: A Polars exploration into Kedro | dev.to | 2023-05-17

The interesting thing about Polars is that it does not try to be a drop-in replacement to pandas, like Dask, cuDF, or Modin, and instead has its own expressive API. Despite being a young project, it quickly got popular thanks to its easy installation process and its “lightning fast” performance.

DataFrame

109 2,258 9.2 C++

C++ DataFrame for statistical, Financial, and ML analysis -- in modern C++ using native types and contiguous memory storage

Project mention: New multithreaded version of C++ DataFrame was released | news.ycombinator.com | 2024-02-13

ArcticDB

4 1,085 9.8 C++

ArcticDB is a high performance, serverless DataFrame database built for the Python Data Science ecosystem.

Project mention: Speed Test - ArcticDB, HDF, Feather, Parquet | /r/algotrading | 2023-11-21

ArcticDB is a new data store for pandas DataFrames (https://arcticdb.io/). I have no affiliation with the project but wanted to see how it would compare on speed versus the other file format storage options available in Pandas: HDF, Feather, and Parquet. I could not find much on-line about how Arctic compares to the other options in terms of speed, so I ran some tests myself.

cylon

3 293 4.8 C++

Cylon is a fast, scalable, distributed memory, parallel runtime with a Pandas like DataFrame. (by cylondata)
mainframe
