Key Features

• Modern C++23 — Built with ranges, concepts, std::expected, and other modern idioms
• Cross-Platform — Builds and runs on Linux, macOS, and Windows
• Spec Compliance — Full table spec support today; Puffin, View, and UDF specs are on the roadmap
• Arrow-Native — Uses the Arrow C Data Interface as the primary data API
