![]() Mid-Level Flight Client: A new FlightClient is available that handles lower level protocol details, and easier to use encoding and decoding APIs.FlightSQL Support: FlightSQL support has been expanded.Comparable Row Format: Much faster multi-column Sorting and Grouping is now possible with the the new spillable, comparable row-format.Support for Copy-On-Write: Arrow arrays now support copy-on-write, via the into_builder methods.These changes allow downstream projects to choose a smaller dependency footprint and build times, if desired. Faster Build Times and Reduced Codegen: The arrow crate has been split into multiple smaller crates, and large kernels have been moved behind optional feature flags.Their performance has more than doubled, and they now support push-driven parsing facilitating async streaming decode from object storage. New CSV and JSON Readers: The CSV and JSON readers have been revamped.The repository recently passed 1400 stars on github, and the community has been focused on performance and feature completeness. When combined, Rust and the Apache Arrow Ecosystem are a compelling toolkit for building the next generation of systems. These features make Rust an excellent choice for building modern high performance analytical systems. The Rust language offers best in class performance, memory safety, and the developer productivity of a modern programming language. The Arrow memory format also supports zero-copy reads for lightning-fast data access without serialization overhead. ![]() Apache Arrow defines a language-independent columnar memory format for flat and hierarchical data, organized for efficient analytic operations on modern hardware like CPUs and GPUs. ArrowĪrrow and arrow-flight are native Rust implementations of Apache Arrow. The most recent list of detailed changes can always be found in the CHANGELOG, with the full historical list available here. With the recent release of 32.0.0 of the Rust implementation of Apache Arrow, it seemed timely to highlight some of the community works since the last update.
