在OneLake 文件资源管理器中,右键单击工作区文件夹,然后从 OneLake中选择 同步。 使用Windows 文件资源管理器查找数据文件。 在工作区文件夹中,查找名称与语义模型匹配的子文件夹,以 结尾。SemanticModel。 语义模型文件夹包含子文件夹中的每个导入-模式表,其中包含 Delta 表的 parquet 文件和日志。
在Microsoft Fabric 中,Power BI 和 SQL 引擎使用 Microsoft Verti-Scan 技术,该技术充分利用 V 顺序优化来加快读取速度。 Spark 和其他引擎不使用 VertiScan 技术,但仍然受益于 V 顺序优化,读取速度可提高约 10%,有时甚至高达 50%。 V 顺序的工作原理是对 Parquet 文件应用特殊排序、行组分布、字典编码和压缩。
