arro3-io

arro3-io is a Python library that provides streaming-capable readers and writers for various Apache Arrow-compatible data formats, including Parquet, Arrow IPC, JSON, and CSV. It is an integral part of the `arro3` ecosystem, which aims to be a minimal Python interface to Apache Arrow's Rust implementation, offering a more lightweight alternative to PyArrow. The library emphasizes a streaming-first approach, enabling efficient processing of larger-than-memory datasets through lazy iterators. It is actively maintained, with the current version being 0.8.0, and integrates seamlessly with other Python data libraries that implement the Arrow PyCapsule Interface.
