cuDF-based GPU backend for Polars [Open Beta]
=============================================
Polars GPU engine
=================

cuDF supports an in-memory, GPU-accelerated execution engine for Python users of the Polars Lazy API.
cuDF provides an in-memory, GPU-accelerated execution engine for Python users of the Polars Lazy API.
The engine supports most of the core expressions and data types as well as a growing set of more advanced dataframe manipulations
and data file formats. When using the GPU engine, Polars will convert expressions into an optimized query plan and determine
whether the plan is supported on the GPU. If it is not, the execution will transparently fall back to the standard Polars engine
