InMemorySnapshotStore
Defined in: src/persistence/snapshot-stores/InMemorySnapshotStore.ts:16
In-process snapshot store. Keeps all snapshots per persistenceId;
loadLatest picks the newest, loadBefore the newest < seq.
Plug-in implementations typically keep only the last N snapshots to
save space — the in-memory one doesn’t bother. Stored state takes the
same PayloadCodec round-trip a real store performs (#888): loads see
the value a real backend would return, and later mutations of the
caller’s object no longer alias into the store.

Section titled “delete()”delete(
persistenceId,toSeq):Promise<void>
Defined in: src/persistence/snapshot-stores/InMemorySnapshotStore.ts:46
Delete snapshots up to and including toSeq. Useful for pruning.

S>(persistenceId,seq,_options?):Promise<Option<Snapshot<S>>>
Defined in: src/persistence/snapshot-stores/InMemorySnapshotStore.ts:37
Load the newest snapshot with sequenceNr < seq, or None.
Type Parameters

Returns

Section titled “Implementation of”loadLatest()
Section titled “loadLatest()”loadLatest<
S>(persistenceId,_options?):Promise<Option<Snapshot<S>>>
Defined in: src/persistence/snapshot-stores/InMemorySnapshotStore.ts:31
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.

Parameters

S>(persistenceId,seq,state,_options?):Promise<Snapshot<S>>
Defined in: src/persistence/snapshot-stores/InMemorySnapshotStore.ts:19
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.
