Pluggable snapshot store. Snapshots short-circuit recovery by fast- forwarding the state machine to a known point, so replay only needs to apply events newer than the snapshot.

persistenceId,toSeq):Promise<void>
Defined in: src/persistence/snapshot-stores/CachedSnapshotStore.ts:89
Delete snapshots up to and including toSeq. Useful for pruning.

S>(persistenceId,seq,options?):Promise<Option<Snapshot<S>>>
Defined in: src/persistence/snapshot-stores/CachedSnapshotStore.ts:84
Load the newest snapshot with sequenceNr < seq, or None.

Defined in: src/persistence/snapshot-stores/CachedSnapshotStore.ts:74
Load the newest snapshot for persistenceId, or None if none exist.
options.encryption is required when client-side encryption was
used at write time — the store has no other way to obtain the
master key. Stores that don’t encrypt ignore the field.

S>(persistenceId,seq,state,options?):Promise<Snapshot<S>>
Defined in: src/persistence/snapshot-stores/CachedSnapshotStore.ts:67
Persist a snapshot at seq — typically the seq of the latest event
applied. Optional options carry per-call preferences from the
caller (e.g. compression/encryption set on the actor). Stores that
cannot honour them silently ignore the field.
