# DataFusion Data Access Layer

[DataFusion](df) is an extensible query execution framework, written in Rust, that uses Apache Arrow as its in-memory format.

This crate is a submodule of DataFusion that provides an `async` API for accessing data, either remotely or locally.
Currently, it is based on the object store interfaces. In the future, this module may include interfaces for accessing
databases, or streaming data.
