Apache DataFusion Session

Apache DataFusion is an extensible query execution framework, written in Rust, that uses Apache Arrow as its in-memory format.

This crate provides session-related abstractions used in the DataFusion query engine. A session represents the runtime context for query execution, including configuration, runtime environment, function registry, and planning.

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.
