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. #![warn(missing_docs)] extern crate arrow; extern crate sqlparser; pub mod datasource; pub mod error; pub mod execution; pub mod logicalplan; pub mod optimizer; pub mod sql; pub mod table; #[cfg(test)] pub mod test;
