| //! DataFusion is an extensible query execution framework that uses |
| //! Apache Arrow as the memory model. |
| //! |
| //! DataFusion supports both SQL and a Table/DataFrame-style API for building logical query plans |
| //! and also provides a query optimizer and execution engine capable of parallel execution |
| //! against partitioned data sources (CSV and Parquet) using threads. |
| //! |
| //! DataFusion currently supports simple projection, selection, and aggregate queries. |
