Type Alias PoolTuningConfig 

pub type PoolTuningConfig = PoolPressureMonitorConfig;

👎Deprecated since 2.0.1:

Use PoolPressureMonitorConfig

Deprecated alias for PoolPressureMonitorConfig.

This type was renamed in v2.0.1 to clarify that pool monitoring operates in recommendation mode only — the pool is not resized at runtime. Use PoolPressureMonitorConfig in new code.

Aliased Type

}

Fields

enabled: bool

Enable adaptive pool sizing. Default: false.

min_pool_size: u32

Minimum pool size. The tuner never shrinks below this value. Default: 5.

max_pool_size: u32

Maximum pool size. The tuner never grows above this value. Default: 50.

target_queue_depth: u32

Maximum acceptable queue depth before scaling up. Default: 3.

scale_up_step: u32

Connections to add per scale-up step. Default: 5.

scale_down_step: u32

Connections to remove per scale-down step. Default: 2.

scale_down_idle_ratio: f64

Minimum idle ratio (idle / total) before considering a scale-down. Default: 0.5 (50% idle connections triggers potential shrink).

tuning_interval_ms: u64

Polling interval in milliseconds. Default: 30 000 (30 s).

samples_before_action: u32

Consecutive samples above threshold required before acting. Default: 3.
