upsert method

@override Future<void> upsert(List<Document> documents)

Inserts documents, replacing any existing document with the same id.

All embeddings must have the same length as the documents already in the store; otherwise an ArgumentError is thrown and the store is left unchanged.

Implementation

@override
Future<void> upsert(List<Document> documents) async {
  await _inner.upsert(documents);
  if (documents.isEmpty) return;
  await _persist();
}
