ETL with Azure Cookbook

By: Christian Cote, Matija Lah, Madina Saitakhmetova

Overview of this book

ETL is one of the most common and tedious procedures for moving and processing data from one database to another. With the help of this book, you will be able to speed up the process by designing effective ETL solutions using the Azure services available for handling and transforming any data to suit your requirements. With this cookbook, you’ll become well versed in all the features of SQL Server Integration Services (SSIS) to perform data migration and ETL tasks that integrate with Azure. You’ll learn how to transform data in Azure and understand how legacy systems perform ETL on-premises using SSIS. Later chapters will get you up to speed with connecting and retrieving data from SQL Server 2019 Big Data Clusters, and even show you how to extend and customize the SSIS toolbox using custom-developed tasks and transforms. This ETL book also contains practical recipes for moving and transforming data with Azure services, such as Data Factory and Azure Databricks, and lets you explore various options for migrating SSIS packages to Azure. Toward the end, you’ll find out how to profile data in the cloud and automate service creation with Business Intelligence Markup Language (BIML). By the end of this book, you’ll have developed the skills you need to create and automate ETL solutions on-premises as well as in Azure.

Loading data into a Big Data Cluster

In this recipe, you are going to design an SSIS package used to load data into a database hosted on the remote SQL Server instance.

The SSIS package contains two control flows:

  • One extracts key information from the line-of-business database, and loads it into a Staging database hosted in Azure
  • The other simulates a process that delivers data from a different source (for instance, managed by another department in your organization, or another organization altogether) and loads it into your Big Data Cluster that is also hosted in Azure

The objective of this SSIS package is to make the necessary data available at the remote location for further processing. The SSIS package that you are going to design in the last recipe of this chapter, entitled Extracting data from a Big Data Cluster, depends on the data made available by the package designed in this recipe.
