| # Apache DataFusion DataSource |
| |
| [Apache DataFusion] 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 defines common DataSource related components like FileScanConfig, FileCompression etc. |
| |
| Most projects should use the [`datafusion`] crate directly, which re-exports |
| this module. If you are already using the [`datafusion`] crate, there is no |
| reason to use this crate directly in your project as well. |
