Struct CheckpointConfig 

pub struct CheckpointConfig {
    pub interval: Duration,
    pub max_snapshots: usize,
    pub storage_path: PathBuf,
    pub enabled: bool,
    pub name_prefix: String,
}

Configuration for periodic actor state checkpointing.

Controls how often snapshots are taken, how many are retained, and where they are stored.

Fields

interval: Duration

Interval between periodic snapshots.

max_snapshots: usize

Maximum number of checkpoints to retain per kernel. When exceeded, the oldest checkpoint is deleted. A value of 0 means unlimited retention.

storage_path: PathBuf

Storage path for file-based checkpoints.

enabled: bool

Whether checkpointing is enabled.

name_prefix: String

Prefix for checkpoint names (e.g., “actor_0”).
