  • polars

    Dataframes powered by a multithreaded, vectorized query engine, written in Rust

    • It's working for me now. :-) To get it working, I used the code from the suggested directory as well as the class PyPolarsError, which I copied into a local module: https://github.com/pola-rs/polars/tree/master/py-polars/src/arrow_interop https://github.com/pola-rs/polars/blob/629f5012bcefaa3c9a9c1a236e64dc057e8d472c/py-polars/src/error.rs Besides the polars dependency, also these are needed:

  • arrow-datafusion

    Apache DataFusion SQL Query Engine

    • A solution for either Polars or Datafusion (or something else?) would be fine. For both libraries, python packages exist, that contain the python bindings: https://github.com/pola-rs/polars/tree/master/py-polars https://github.com/apache/arrow-datafusion/tree/master/python

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
