Get Started with Databricks for Data Engineering - Mandarin Chinese
本课程介绍在 Databricks Data Intelligence Platform 上执行基础数据工程工作流所需的核心技能。您将探索工作区、使用 Unity Catalog,并学习数据工程师在 Databricks 上日常使用的基础构建模块。
本课程采用实操方式。您首先熟悉工作区,然后针对每个主题完成配套的演示(Demo)和实验(Lab)笔记本。演示会由讲师或引导式笔记本带您了解某个概念;实验则要求您自行应用刚刚所学的内容。
课程内容涵盖:
• Databricks Data Intelligence Platform,以及 Databricks 工作区、Unity Catalog 和笔记本如何协同运作。
• 创建和管理 Delta Lake 表。
• 使用 INSERT、UPDATE 和 DELETE 修改数据。
• 探索 Delta 表的版本历史记录和时间旅行。
• 使用 Lakeflow Connect 选项(CTAS、上传 UI 和 COPY INTO)引入数据。
• 构建奖牌架构管道,通过 Bronze、Silver 和 Gold 层转换数据。
• 使用 Lakeflow Jobs 实现管道自动化。
• (附加内容)使用 Spark Declarative Pipelines 构建声明式管道。
• 对云数据平台有基本了解。您在概念层面理解什么是数据库、表和查询。
• 具备 SQL 的实用知识。您能够读写包含 WHERE、GROUP BY 和聚合函数的 SELECT 语句,并理解 INSERT、UPDATE 和 DELETE。
• 对数据引入、转换和管道等数据工程概念有总体了解会有所帮助,但并非必需——本课程会介绍这些基础内容。
