Chapter 4. Working with ADLS

Azure Data Lake Store (ADLS) is a file system designed for use as a hyper-scale repository for big data analytic workloads.

The features of ADLS include:

  • Hierarchical filesystem containing folders, which in turn contain data stored as files.

  • Provides unlimited storage without imposing any limits on account sizes, file sizes, or the amount of data that can be stored in a data lake.

  • Compatible with Hadoop Distributed File System (HDFS).

  • Can be accessed by Hadoop application via the WebHDFS-compatible REST APIs or the ADLS connector.

  • Uses Azure Active Directory (AAD) for identity and access management.

For more general information on ADLS, refer to Get Started with Azure Data Lake Store Using the Azure Portal in Azure documentation.
