DataFrame interoperatiblity - what's been achieved, and what comes next?

Marco Gorelli

In 2023, we saw several libraries - which had previously only supported pandas - add support for other dataframe libraries such as Polars, Modin, and cuDF. - How did they do it? - Are there any drawbacks to how they did it? - What comes next, and what other solutions are there? This talk could be of interest to anyone working with dataframes. In particular, those maintaining or contributing to libraries which use dataframes will learn about how they can best support multiple dataframe libraries.
