LazyFrame rename(Map<String, String> mapping, {bool strict = true}) {
  if (mapping.isEmpty) {
    throw ArgumentError.value(mapping, 'mapping', 'must not be empty');
  }
  for (final entry in mapping.entries) {
    _validateName(entry.key, 'mapping key');
    _validateName(entry.value, 'mapping value');
  }
  return _inputCommand('lazyRename', {
    'existing': mapping.keys.toList(growable: false),
    'new': mapping.values.toList(growable: false),
    'strict': strict,
