StateSnapshot

Durable persistence of volatile state

Definition

Mechanism

Periodic serialization of internal volatile State to durable storage to enable crash recovery. Unlike distributed checkpoints (which requires consensus), Snapshot is a local or unilateral durability guarantee. It enables 'Resume' functionality. Utilizes Trace, IdempotentWrite.

Preconditions

  1. Serializable State
  2. Write access to durable storage

Postconditions

  1. Resume point established

Invariants

  1. Atomicity: Snapshot is either fully written or discarded (no partial corruption)
  2. Roundtrip Integrity: Deserialize(Serialize(S)) must equal S

Risks

Failure modes

None stated.
