pub enum WritePolicy {
WriteThrough,
WriteBack,
WriteAround,
}Expand description
How a put propagates across the tiers. See the module docs for the full
contract; every policy persists both durable tiers before returning.
Variants§
WriteThrough
Durable tiers (L2, L3) first, then warm L1. Crash-safe. The default.
WriteBack
Warm L1 first (immediate hot availability), then persist durable tiers before returning. Crash-safe (no ack before the durable flush).
WriteAround
Durable tiers only; skip L1 (it fills lazily on read-through).
