What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

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
