Azure Databricks is an analytics platform powered by Apache Spark. Spark is a unified analytics engine capable of working with virtually every major database, data caching service, and data warehouse provider.
However, Spark clusters in Databricks also support Scala, since Apache Spark is built on Scala. Scala is a high-level programming language that combines aspects of both functional and object-oriented programming to form a concise language that is especially useful in an environment like Databricks. Using Databricks's built-in support for data analytics with Scala's ability to efficiently interact with resources in a customizable way gives companies a high level of control over their data and analytics.
In this lab, you'll use Scala in an Azure Databricks cluster to interact with Azure Data Lake Storage Gen2, including ingesting, transforming, and writing data to the store.
Learning Objectives
Upon completion of this lab you will be able to:
- Load data into Azure Data Lake Storage Gen2
- Create and manage a Databricks workspace
- Create and manage a Databricks cluster

- Use Scala to create DataFrames from data in ADLS Gen2
Intended Audience
This lab is intended for:
- Azure administrators
- Cloud engineers and solutions architects
- Data engineers
- Anyone with a need to visualize and analyze data in Azure
Prerequisites
You should be familiar with:
- Basic familiarity with the Azure Portal is helpful, but not required
