| # User Guide |
| |
| Apache DataFusion Java is a thin Java binding over the |
| [Apache DataFusion](https://datafusion.apache.org/) query engine. SQL and |
| DataFrame queries execute in native Rust; results return to the JVM as |
| [Apache Arrow](https://arrow.apache.org/) record batches over the Arrow C |
| Data Interface. |
| |
| This guide covers installation, the `SessionContext` and `DataFrame` APIs, |
| and Parquet ingestion. |
