# 数据目录

> ClickHouse Cloud 的数据目录集成

export const BetaBadge = ({link, galaxyTrack, galaxyEvent}) => {
  if (link) {
    return <a href={link} target="_blank" rel="noopener noreferrer" className="betaBadge" onClick={galaxyTrack && galaxyEvent ? galaxyOnClick(galaxyEvent) : undefined}>
                <span>Beta</span>
            </a>;
  }
  return <a href="https://clickhouse.com/docs/reference/settings/beta-and-experimental-features#beta-features" className="betaBadge">
            <span>Beta 版功能</span>
        </a>;
};

export const Image = ({img, alt, size = "lg"}) => {
  const normalizedSize = ["sm", "md", "lg"].includes(size) ? size : "lg";
  return <div className={`ch-image-${normalizedSize}`}>
      <Frame>
        <img src={img} alt={alt} />
      </Frame>
    </div>;
};

ClickHouse Cloud 可直接连接到开放表格式数据目录，让您无需复制数据即可访问数据湖中的表。
通过此集成，数据目录中的表会作为可查询的数据库显示在 ClickHouse 中。
可通过 SQL 命令 ([DataLakeCatalog](/zh/reference/engines/database-engines/datalake)) 或 ClickHouse Cloud UI 的“数据源”选项卡进行设置。

使用 UI：

* 通过使用与 Data Catalog 对象一致字段的表单，简化设置流程
* 为已启用的数据目录集成提供统一界面
* 保存时测试连接和凭证
