# min_relative_* MergeTree 表设置

> 自动生成的 min_relative_* 分组中的 ClickHouse 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，并且由 ClickHouse 源代码自动生成。

<div id="min_relative_delay_to_close">
  ## min\_relative\_delay\_to\_close
</div>

<SettingsInfoBlock type="UInt64" default_value="300" />

相对其他副本的最小延迟；达到该延迟后，将关闭、停止处理请求，并且在状态检查中不返回 Ok。

<div id="min_relative_delay_to_measure">
  ## min\_relative\_delay\_to\_measure
</div>

<SettingsInfoBlock type="UInt64" default_value="120" />

仅当绝对延迟不低于此值时，才会计算相对副本延迟。

<div id="min_relative_delay_to_yield_leadership">
  ## min\_relative\_delay\_to\_yield\_leadership
</div>

<SettingsInfoBlock type="UInt64" default_value="120" />
