Everything about Apache DataFusion
Open-source analytical query engine
Apache DataFusion is an open-source, extensible analytical query engine written in Rust, built on Apache Arrow's columnar memory format. It provides SQL and DataFrame interfaces for analytical query execution and is designed to be used as a library by developers building databases, query engines, and analytical tools, rather than as a standalone database server. The project originated in 2017, was donated to the Apache Arrow project in 2019, and became a top-level project of the Apache Software Foundation in 2024. As of March 2026, DataFusion exceeded one million monthly downloads on crates.io. Wikipedia →
