//! 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.
