| //! Session management for DataFusion query execution environment |
| //! |
| //! This module provides the core session management functionality for DataFusion, |
| //! handling both Catalog (Table) and Datasource (File) configurations. It defines |
| //! the fundamental interfaces and implementations for maintaining query execution |
| //! state and configurations. |
| //! |
| //! Key components: |
| //! * [`Session`] - Manages query execution context, including configurations, |
| //! catalogs, and runtime state |
| //! * [`SessionStore`] - Handles session persistence and retrieval |
| //! |
| //! The session system enables: |
| //! * Configuration management for query execution |
| //! * Catalog and schema management |
| //! * Function registry access |
| //! * Runtime environment configuration |
| //! * Query state persistence |
