Struct CheckpointPolicy 

pub struct CheckpointPolicy {
    pub max_checkpoints: usize,
    pub keep_every_n: u64,
    pub delta_threshold_bytes: u64,
}

Controls eviction and storage-format decisions made by the manager.

Fields

max_checkpoints: usize

Maximum number of checkpoints retained before eviction. Defaults to 10.

keep_every_n: u64

Every keep_every_n versions a full checkpoint is unconditionally stored (instead of a delta). Defaults to 5.

delta_threshold_bytes: u64

If a checkpoint’s full_bytes exceeds this threshold the manager will attempt to store it as a delta instead. Defaults to 1 MiB.
