Struct AdaptiveCheckpointConfig 

pub struct AdaptiveCheckpointConfig {
    pub min_interval: Duration,
    pub max_interval: Duration,
    pub target_overhead_ratio: f64,
    pub smoothing_alpha: f64,
}

Configuration for adaptive checkpoint intervals.

Dynamically adjusts the checkpoint interval based on observed checkpoint durations: interval = clamp(smoothed_duration / target_ratio, min, max).

This avoids checkpointing too frequently under light load (wasting I/O) or too infrequently under heavy load (increasing recovery time).

Fields

min_interval: Duration

Minimum checkpoint interval (floor). Default: 10s.

max_interval: Duration

Maximum checkpoint interval (ceiling). Default: 300s.

target_overhead_ratio: f64

Target ratio of checkpoint duration to interval.

For example, 0.1 means checkpoints should take at most 10% of the time between them. Default: 0.1.

smoothing_alpha: f64

EMA smoothing factor for checkpoint durations.

Higher values give more weight to recent observations. Range: 0.0–1.0. Default: 0.3.
