About Apache Arrow

A development platform for in-memory analytics, defining a standard columnar memory format for flat and hierarchical data that enables efficient exchange between systems and languages. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
