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.
