이러한 설정은 [system.merge\_tree\_settings](/docs/ko/reference/system-tables/merge_tree_settings)에서 확인할 수 있으며, ClickHouse 소스에서 자동으로 생성됩니다.

<div id="enable_block_number_column">
  ## enable\_block\_number\_column
</div>

<SettingsInfoBlock type="Bool" default_value="0" />

각 행에 대해 \_block\_number 컬럼을 저장하도록 설정합니다.

<div id="enable_block_offset_column">
  ## enable\_block\_offset\_column
</div>

<SettingsInfoBlock type="Bool" default_value="0" />

머지 시 가상 컬럼 `_block_offset`을 저장합니다.
