Why we included this project
Apache Arrow is the columnar memory format that data systems use to move and process tabular data without the usual serialization overhead. Its zero-copy reads let analytics engines, data pipelines, and ML feature stores exchange data across languages, and the project ships mature bindings for C++, Python, Java, Go, Rust, and more. The Flight RPC protocol extends that to streaming between services. If you're building anything that handles large in-memory datasets, Arrow is the layer that keeps performance predictable, which is why so many data stacks are built on it.
