A Rust implementation of the Apache Arrow columnar in-memory format, supporting IO with Parquet, Avro, CSV, IPC, and Flight, plus compute kernels. It was one of the most feature-complete Arrow implementations but is officially unmaintained as of January 2024.
Use cases
- read and write parquet files in rust
- work with apache arrow columnar data in rust
- convert csv to arrow ipc format
- read avro files fast in rust
- columnar data processing and compute kernels in rust
- interop between rust and arrow-based data systems
When to choose
- you need Arrow/Parquet/Avro support in Rust and are pinned to an older, stable codebase
- you need the C data interface for FFI interop with other Arrow implementations
- you need fine-grained control over bitmaps, mutability, and zero-copy layouts
When to avoid
- starting a new project - the crate is explicitly unmaintained since 2024-01-17
- you need bug fixes, security patches, or new Arrow spec features
- you need Decimal 256 or deeply nested Parquet types
- consider the official apache/arrow-rs crate instead
