🌪️ Vortex

📚 Documentation | 📊 Performance Benchmarks

Overview

Vortex is a next-generation columnar file format and toolkit designed for high-performance data processing. It is the fastest and most extensible format for building data systems backed by object storage. It provides:

⚡️ Blazing Fast Performance
- 200x faster random access reads (vs. modern Apache Parquet)
- 2-10x faster scans
- 2-10x faster writes
- Similar compression ratios
- Efficient support for wide tables with zero-copy/zero-parse metadata
🔧 Extensible Architecture
- Modeled after Apache DataFusion's extensible approach
- Pluggable encoding system, type system, compression strategy, & layout strategy
- Zero-copy compatibility with Apache Arrow
🗳️ Open Source, Neutral Governance
- A Linux Foundation (LF AI & Data) Project
- Apache-2.0 Licensed
↔️ Integrations
- Arrow, DataFusion, DuckDB, Spark, Pandas, Polars, & more
- Apache Iceberg (coming soon)

🟢 Development Status: Library APIs may change from version to version, but we now consider the file format stable. From release 0.36.0, all future releases of Vortex should maintain backwards compatibility of the file format (i.e., be able to read files written by any earlier version >= 0.36.0).

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.

cargo add vortex

Python Package

uv add vortex-data

Command Line UI (vx)

For browsing the structure of Vortex files, you can use the vx command-line tool.

# 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)

# 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, we suggest using MiMalloc:

#[global_allocator]
static GLOBAL_ALLOC: MiMalloc = MiMalloc;
