@override Stream<Iterable<Map<String, dynamic>>> lazy([ int chunk = 100, String column = 'id' ])

Implementation

@override
Stream<Iterable<Map<String, dynamic>>> lazy([
  int chunk = 100,
  String column = 'id',
]) async* {
  int offset = 0;
  while (true) {
    orderByAsc(column).limit(chunk).offset(offset);
    final result = await get();
    if (result.isEmpty) {
      break;
    }
    yield result;
    offset += chunk;
    if (result.length < chunk) {
      break;
    }
  }
}
