Overview of this book

This new edition of the Azure Data Factory book, fully updated to reflect ADS V2, will help you get up and running by showing you how to create and execute your first job in ADF. There are updated and new recipes throughout the book based on developments happening in Azure Synapse, Deployment with Azure DevOps, and Azure Purview. The current edition also runs you through Fabric Data Factory, Data Explorer, and some industry-grade best practices with specific chapters on each. You’ll learn how to branch and chain activities, create custom activities, and schedule pipelines, as well as discover the benefits of cloud data warehousing, Azure Synapse Analytics, and Azure Data Lake Gen2 Storage. With practical recipes, you’ll learn how to actively engage with analytical tools from Azure Data Services and leverage your on-premises infrastructure with cloud-native tools to get relevant business insights. You'll familiarize yourself with the common errors that you may encounter while working with ADF and find out the solutions to them. You’ll also understand error messages and resolve problems in connectors and data flows with the debugging capabilities of ADF. By the end of this book, you’ll be able to use ADF with its latest advancements as the main ETL and orchestration tool for your data warehouse projects.

NOTE

To make fully understanding the recipes easier, we make naming suggestions for the accounts, pipelines, and so on throughout the chapter. Many services, such as Azure Storage and SQL Server, require that the names you assign are unique. Follow your own preferred naming conventions, making appropriate substitutions as you follow the recipes. For the Azure resource naming rules, refer to the documentation at https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/resource-name-rules.

In addition to Azure Data Factory, we shall be using three other Azure services: Logic Apps, Blob Storage, and Azure SQL Database. You will need to have Azure Blob Storage and Azure SQL Database accounts set up to follow the recipes. The following steps describe the necessary preparation:

  • Create an Azure Blob Storage account and name it adforchestrationstorage. When creating the storage account, select the same region (that is, East US) as you selected when you created the Data Factory instance. This will reduce our costs when moving data.
  • Create a container named data within this storage account, and upload two CSV files to the folder: airlines.csv and countries.csv (the files can be found on GitHub: https://github.com/PacktPublishing/Azure-Data-Factory-Cookbook/tree/master/data).
  • Create an Azure SQL Database instance and name it AzureSQLDatabase. When you create the Azure SQL Database instance, you will have the option of creating a server on which the SQL database will be hosted. Create that server and take note of the credentials you entered. You will need these credentials later when you log in to your database.

Choose the basic configuration for your SQL server to save on costs. Once your instance is up and running, configure the Networking settings for the SQL server as highlighted in Figure 2.1. Go to the Networking page under the Security menu, then under Firewall rules, create a rule to allow your IP to access the database. Under Exceptions, make sure that you check the Allow Azure services and resources to access this database option.

Download the following SQL scripts from GitHub at https://github.com/PacktPublishing/Azure-Data-Factory-Cookbook/tree/master/Chapter02/sql-scripts:

  • CreateAirlineTable.sql and CreateCountryTable.sql: These scripts will add two tables, Country and Airline, which are used in several recipes, including the first one.
  • CreateMetadataTable.sql: This will create the FileMetadata table and a stored procedure to insert data into that table. This table is necessary for the Using Metadata and Stored Procedure activities and Filtering your data and looping through your files recipes.
  • CreateActivityLogsTable.sql: This will create the PipelineLog table and a stored procedure to insert data into that table. This table is necessary for the Chaining and branching activities within your pipeline recipe.
  • CreateEmailRecipients.sql: This script will create the EmailRecipients table and populate it with a record. This table is used in the Using the Lookup, Web, and Execute Pipeline activities recipe. You will need to edit it to enter email recipient information.

To create tables from the downloaded files, open your Azure SQL Database instance, go to the Query editor page, then paste the SQL scripts from the downloaded files and run them one by one.

Now that we’re all set up, let’s move on to the first recipe.
