Overview of this book

Azure Databricks is a unified collaborative platform for performing scalable analytics in an interactive environment. The Azure Databricks Cookbook provides recipes to get hands-on with the analytics process, including ingesting data from various batch and streaming sources and building a modern data warehouse. The book starts by teaching you how to create an Azure Databricks instance within the Azure portal, Azure CLI, and ARM templates. You’ll work through clusters in Databricks and explore recipes for ingesting data from sources, including files, databases, and streaming sources such as Apache Kafka and EventHub. The book will help you explore all the features supported by Azure Databricks for building powerful end-to-end data pipelines. You'll also find out how to build a modern data warehouse by using Delta tables and Azure Synapse Analytics. Later, you’ll learn how to write ad hoc queries and extract meaningful insights from the data lake by creating visualizations and dashboards with Databricks SQL. Finally, you'll deploy and productionize a data pipeline as well as deploy notebooks and Azure Databricks service using continuous integration and continuous delivery (CI/CD). By the end of this Azure book, you'll be able to use Azure Databricks to streamline different processes involved in building data-driven apps.

Understanding and creating RBAC in Azure for ADLS Gen-2

In this chapter, you will be learning how to allow AAD users to securely access the files and directories in an ADLS Gen-2 storage account using AAD authentication from Azure Databricks. ADLS Gen-2 supports two methods for securing access to the data lake via security principals:

  • Role-Based Access Control (RBAC): Used to restrict access to the Storage Account and to individual containers in theStorage Account.
  • POSIX-like Access Control Lists (ACLs): Used to restrict access to individual folders and files.

In this recipe, you will learn how to use RBAC to control access at the container level in an ADLS Gen-2 Storage Account.

Getting ready

RBAC uses role assignments to apply sets of permissions to a user, group, service principal, or managed identity that is present in Azure Active Directory (AAD) and is requesting access to Azure resources.

With RBAC, Azure resources are constrained as top-level resources...
