PostgresSnapshotStore
Esta página aún no está disponible en tu idioma.
Defined in: src/persistence/snapshot-stores/PostgresSnapshotStore.ts:35
SnapshotStore backed by PostgreSQL (pg). One row per
(persistence_id, sequence_nr); loadLatest is an indexed
ORDER BY sequence_nr DESC LIMIT 1. Prune-on-save keeps the newest
keepN. PersistenceOptions (compression/encryption) are ignored —
like the SQLite and Cassandra stores, payloads are stored as JSON text.

Section titled “delete()”delete(
pid,toSeq):Promise<void>
Defined in: src/persistence/snapshot-stores/PostgresSnapshotStore.ts:94
Delete snapshots up to and including toSeq. Useful for pruning.

Section titled “loadBefore()”loadBefore<
S>(pid,seq,_options?):Promise<Option<Snapshot<S>>>
Defined in: src/persistence/snapshot-stores/PostgresSnapshotStore.ts:84
Load the newest snapshot with sequenceNr < seq, or None.

Section titled “Implementation of”loadLatest()
Section titled “loadLatest()”Defined in: src/persistence/snapshot-stores/PostgresSnapshotStore.ts:74
Load the newest snapshot for pid, 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>(pid,seq,state,_options?):Promise<Snapshot<S>>
Defined in: src/persistence/snapshot-stores/PostgresSnapshotStore.ts:52
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.
