Implementation

@override
Future<void> openBackend() async {
  if (_db != null) return;
  final db = SqliteDatabase.open(atSign, dbPath);
  final keyStore = SqliteAtKeyValueStore(db, atSign);
  await keyStore.initialize();
  final queue = AtSyncQueue(atSign: atSign);
  await queue.open(store: SqliteSyncQueueStore(db));
  _db = db;
  _keyStore = keyStore;
  _queue = queue;
}
