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.

Generating your first Azure Data Factory

Now we will hop on the cloud and start playing with Azure Data Factory. Working in Biml with Azure Data Factory is outside the realms of a BimlExpress add-on and requires the BimlStudio standalone application to work. For the purpose of Azure Data Factory recipes, you can install a trial version of BimlStudio, which will let you try it out for free for 30 days.

What I want to show in this recipe is how to generate and deploy a simple Data Factory in BimlStudio 2019. This Data factory will have two linked services, two datasets, and one Copy Activity that copies data from the source Http dataset to the sink Azure Data Lake Storage Gen2 dataset. The Http linked service is pointing to an open data source, https://cadatacatalog.state.gov/. We will also write a PowerShell script that will deploy this Data Factory code to Azure.

Getting ready

Download and install a trial version of the Varigence BimlStudio 2019 from https://varigence.com...
