base on An extensible, state of the art columnar file format 🌪️ Vortex ========= [](https://github.com/spiraldb/vortex/actions) [](https://crates.io/crates/vortex-array) [](https://docs.rs/vortex-array) [](https://pypi.org/project/vortex-array/) 📚 [Documentation](https://docs.vortex.dev/) | 📊 [Performance Benchmarks](https://bench.vortex.dev) ## Overview Vortex is a next-generation columnar file format and toolkit designed for high-performance data analytics. It provides: - **⚡️ Blazing Fast Performance** - 100-200x faster random access reads than Apache Parquet - 2-10x faster scans with similar compression ratios and write throughput - Efficient support for wide tables with zero-copy/zero-parse metadata - **🔧 Extensible Architecture** - Modeled after Apache DataFusion's extensible approach - Pluggable encoding system - Zero-copy compatibility with Apache Arrow > 🚧 **Development Status**: This project is under active development. APIs and file formats may change, and some > features are still being implemented. ## Key Features ### Core Capabilities - ✨ **Logical Types** - Clean separation between logical schema and physical layout - 🔄 **Zero-Copy Arrow Integration** - Seamless conversion to/from Apache Arrow arrays - 🧩 **Extensible Encodings** - Pluggable physical layouts with built-in optimizations - 📦 **Cascading Compression** - Support for nested encoding schemes - 🚀 **High-Performance Computing** - Optimized compute kernels for encoded data - 📊 **Rich Statistics** - Lazy-loaded summary statistics for optimization ### Technical Architecture #### Logical vs Physical Design Vortex strictly separates logical and physical concerns: - **Logical Layer**: Defines data types and schema - **Physical Layer**: Handles encoding and storage implementation - **Built-in Encodings**: Compatible with Apache Arrow's memory format - **Extension Encodings**: Optimized compression schemes (RLE, dictionary, etc.) ## Quick Start ### Installation #### Rust Crate All features are exported through the main `vortex` crate. ```bash cargo add vortex ``` #### Python Package ```bash uv add vortex-array ``` #### Command Line UI (vx) For browsing the structure of Vortex files, you can use the `vx` command-line tool. ```bash # Install latest release cargo install vortex-tui --locked # Or build from source cargo install --path vortex-tui --locked # Usage vx browse <file> ``` ### Development Setup #### Prerequisites (macOS) ```bash # Optional but recommended dependencies brew install flatbuffers protobuf # For .fbs and .proto files brew install duckdb # For benchmarks # Install Rust toolchain curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # or brew install rustup # Initialize submodules git submodule update --init --recursive # Setup dependencies with uv uv sync --all-packages ``` ### Performance Optimization For optimal performance, use [MiMalloc](https://github.com/microsoft/mimalloc): ```rust #[global_allocator] static GLOBAL_ALLOC: MiMalloc = MiMalloc; ``` ## Project Information ### License Licensed under the Apache License, Version 2.0 ### Governance Vortex is committed to remaining open-source, following governance models inspired by the [Substrait project](https://substrait.io/governance/) and Apache Software Foundation. ### Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines. ## Acknowledgments 🏆 This project builds upon groundbreaking work from the academic and open-source communities: ### Key Research Papers - [BtrBlocks](https://www.cs.cit.tum.de/fileadmin/w00cfj/dis/papers/btrblocks.pdf) - Efficient columnar compression - [FastLanes](https://www.vldb.org/pvldb/vol16/p2132-afroozeh.pdf) - High-performance integer compression - [FSST](https://www.vldb.org/pvldb/vol13/p2649-boncz.pdf) - Fast random access string compression - [ALP](https://ir.cwi.nl/pub/33334/33334.pdf) - Adaptive lossless floating-point compression - [Procella](https://dl.acm.org/citation.cfm?id=3360438) - YouTube's unified data system - [Cloud Object Storage Analytics](https://www.durner.dev/app/media/papers/anyblob-vldb23.pdf) - High-performance analytics - [ClickHouse](https://www.vldb.org/pvldb/vol17/p3731-schulze.pdf) - Fast analytics for everyone ### Open Source Inspiration - [Apache Arrow](https://arrow.apache.org) & [Apache DataFusion](https://github.com/apache/datafusion) - [parquet2](https://github.com/jorgecarleitao/parquet2) by Jorge Leitao - [DuckDB](https://github.com/duckdb/duckdb) - [Velox](https://github.com/facebookincubator/velox) & [Nimble](https://github.com/facebookincubator/nimble) --- *Thanks to all contributors who have shared their knowledge and code with the community!
