Arrow-rs is the official Rust implementation of Apache Arrow, providing native support for the Arrow columnar in-memory format and Apache Parquet columnar file format.
The project solves the problem of working with columnar data in Rust by providing a complete implementation of the Arrow specification. It offers core functionality including memory layout, arrays, and low-level computations through its main arrow crate, alongside specialized support for the Parquet file format and the Arrow-Flight IPC protocol. The implementation enables efficient data interchange and processing in Rust applications that need to work with columnar data structures.
Developers should adopt this tool when building Rust applications that need to read, write, or process columnar data, particularly those integrating with the broader Arrow ecosystem. It suits projects requiring Parquet file support, inter-process communication via Arrow-Flight, or compatibility with other Arrow implementations across languages. The repository is organized as a multi-crate workspace, with the core arrow crate providing fundamental functionality, the parquet crate handling columnar file format operations, arrow-flight enabling protocol support, and parquet-derive offering convenient macros for deriving record readers and writers.
Development activity shows active engagement with the community through multiple channels including GitHub issues and pull requests for technical discussions, an active mailing list for broader Arrow community coordination, and informal coordination spaces including a dedicated Discord server and ASF Slack channel. The project maintains a structured contribution process documented in its contributing guide and security policy, with all technical designs formalized in GitHub to ensure accessibility across the community.
