课程名称：Apache Drill：实践课程 课程概述：Apache Drill 是一个无模式的 SQL 查询引擎，适用于 Hadoop、NoSQL 和云存储。Apache Drill 的主要亮点包括： 1. 敏捷性：无需数据加载、模式创建和维护、转换等开销，即可快速获得洞察。 2. 灵活性：可以直接分析非关系型数据存储中的多结构和嵌套数据，而无需转换或限制数据。 3. 熟悉度：能够利用现有的 SQL 技能和商业智能工具（如 Tableau、Qlikview、MicroStrategy、Spotfire、Excel 等）。 Apache Drill 的架构可以扩展到数千台服务器，并且由于其架构设计，其性能非常高效。该课程不仅涵盖如何使用 Drill 连接和查询不同的数据源，还解释了 Drill 的工作原理，以及为什么它优于其他查询引擎，如 Spark、Presto 和 Impala。Drill 是用于交互式数据探索的首选工具，具有无缝连接各种数据存储和无模式数据探索的能力，成为分析师工具包中的必备工具。Drill 使用 ANSI SQL 进行查询，将每份数据视为表格，即使它并不是真正的表格，使查询过程变得非常简单。 课程内容包括： - 从零开始解释 Apache Drill 的概念和能力的完整课程。 - 每一个 Apache Drill 概念都通过实践进行详细讲解。 - 包括在官方文档中解释不清的相关概念。 - 课程附带相关命令和讲座中使用的数据集，方便学习。 该课程适合希望深入了解 Apache Drill 并掌握其应用的学习者。
Apache Drill is a Schema-free SQL Query Engine for Hadoop, NoSQL and Cloud Storage. The major highlights of Apache Drill are:1. Agility: Get faster insights without the overhead (data loading, schema creation and maintenance, transformations, etc.)2. Flexibility: Analyze the multi-structured and nested data in non-relational datastores directly without transforming or restricting the data3. Familiarity: Leverage your existing SQL skillsets and BI tools including Tableau, Qlikview, MicroStrategy, Spotfire, Excel and moreApache Drill can scale upto 1000s of servers, and is very high performant because of the way it is architected. This course not only covers how to use Drill to connect and query different data sources, but also explains the functioning of Drill and why it beats query engines like Spark, Presto and Impala.Drill is a go-to tool for interactive Data Exploration. With its capability to connect seamlessly to any data store, and schema-free data exploration, it has become a go-to tool in the analyst's toolkit. Drill uses ANSI SQL for querying, and treats every data like a table, even if it is not, making it very easy to use for querying purposes.What's included in the course?Complete course on Apache Drill concepts and capabilities explained from Scratch.Each and Every Apache Drill concept is explained with a HANDS-ON.Includes even those concepts, the explanation to which is not very clear even in Drill official documentation.Related Commands and Datasets used in lectures are attached in the course for your convenience.
