> ClickHouse 在 use_minimalistic_* 生成分组中的 MergeTree 表设置。

export const SettingsInfoBlock = ({type, default_value, changeable_without_restart}) => {
  return <div className="not-prose" style={{
    display: "flex",
    flexWrap: "wrap",
    alignItems: "baseline",
    columnGap: "0.5rem",
    rowGap: "0.125rem",
    margin: "0.375rem 0",
    fontSize: "0.8125rem",
    lineHeight: "1.125rem"
  }}>
      <div style={{
    fontWeight: 600,
    opacity: 0.72
  }}>类型</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{type}</div>
      <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>默认值</div>
      <div style={{
    overflowWrap: "anywhere"
  }}>{default_value}</div>
      {changeable_without_restart && <div style={{
    fontWeight: 600,
    opacity: 0.72,
    marginInlineStart: "0.5rem"
  }}>
          无需重启即可更改
        </div>}
      {changeable_without_restart && <div style={{
    overflowWrap: "anywhere"
  }}>
          {changeable_without_restart}
        </div>}
    </div>;
};

这些设置可在 [system.merge\_tree\_settings](/docs/zh/reference/system-tables/merge_tree_settings) 中查看，且由 ClickHouse 源代码自动生成。

<div id="use_minimalistic_checksums_in_zookeeper">
  ## use\_minimalistic\_checksums\_in\_zookeeper
</div>

<SettingsInfoBlock type="Bool" default_value="1" />

对 ZooKeeper 中分片的校验和使用较小的格式 (数十字节) ，而不是
常规格式 (数十 KB) 。启用前，请确认所有副本都支持
新格式。

<div id="use_minimalistic_part_header_in_zookeeper">
  ## use\_minimalistic\_part\_header\_in\_zookeeper
</div>

<SettingsInfoBlock type="Bool" default_value="1" />

ZooKeeper 中数据分片头部的存储方式。启用后，ZooKeeper
存储的数据会更少。有关详情，请参阅[此处](/docs/zh/reference/settings/server-settings/settings#use_minimalistic_part_header_in_zookeeper)。
