Apache DataFusion Python

A Python library that provides bindings to the Apache Arrow in-memory query engine, DataFusion. It enables users to build and execute high-performance queries using SQL or a DataFrame API against various data sources, including CSV, Parquet, JSON, and in-memory data. Leveraging its Rust-written query engine, it focuses on efficient, zero-copy data exchange with PyArrow. The library is actively maintained, with a current version of 52.3.0, and typically releases in sync with the core DataFusion project.
