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.

Designing a Custom Control Flow Task

To determine whether, in a given situation, you actually need customization or not, you need to ask yourself two questions:

  • Can the required operation be performed using one or more natively provided tasks or components in an efficient way that will remain scalable and not compromise the maintainability of the solution?
  • Would the given operation only be needed in this one particular situation, or is it reasonable to expect that a similar operation might be required elsewhere, or at a later time?

If using the built-in features to address an otherwise unsupported requirement might negatively affect the efficiency of the solution, reduce its scalability, or increase its complexity, then customization should certainly be considered.

In SSIS, you can implement your own programmatic logic by using two different techniques – both built into the platform: by providing the custom code in a Script Task or a Script Component, or...
