1//! Connection Pooling Modes - HeliosProxy
2//!
3//! Implements three connection pooling modes for optimized backend connection sharing:
4//!
5//! - **Session Mode**: 1:1 client-to-backend mapping (current default behavior)
6//! - **Transaction Mode**: Return connection to pool after COMMIT/ROLLBACK
7//! - **Statement Mode**: Return connection after each statement (most aggressive)
8//!
9//! # Feature Flag
10//!
11//! This module requires the `pool-modes` feature flag.
12//!
13//! # Usage
14//!
15//! ```rust,ignore
16//! use heliosdb_proxy::pool::{PoolingMode, ConnectionPoolManager, PoolModeConfig};
17//!
18//! let config = PoolModeConfig {
19//!     default_mode: PoolingMode::Transaction,
20//!     max_pool_size: 100,
21//!     ..Default::default()
22//! };
23//!
24//! let manager = ConnectionPoolManager::new(config);
25//! let lease = manager.acquire(client_id, &node).await?;
26//! // Use connection...
27//! manager.release(lease).await;
28//! ```
