18//! Session management for DataFusion query execution environment
19//!
20//! This module provides the core session management functionality for DataFusion,
21//! handling both Catalog (Table) and Datasource (File) configurations. It defines
22//! the fundamental interfaces and implementations for maintaining query execution
23//! state and configurations.
24//!
25//! Key components:
26//! * [`Session`] - Manages query execution context, including configurations,
27//!   catalogs, and runtime state
28//! * [`SessionStore`] - Handles session persistence and retrieval
29//!
30//! The session system enables:
31//! * Configuration management for query execution
32//! * Catalog and schema management
33//! * Function registry access
34//! * Runtime environment configuration
35//! * Query state persistence
