Overview of this book

Azure Data Factory (ADF) is a modern data integration tool available on Microsoft Azure. This Azure Data Factory Cookbook helps you get up and running by showing you how to create and execute your first job in ADF. You’ll learn how to branch and chain activities, create custom activities, and schedule pipelines. This book will help you to discover the benefits of cloud data warehousing, Azure Synapse Analytics, and Azure Data Lake Gen2 Storage, which are frequently used for big data analytics. With practical recipes, you’ll learn how to actively engage with analytical tools from Azure Data Services and leverage your on-premise infrastructure with cloud-native tools to get relevant business insights. As you advance, you’ll be able to integrate the most commonly used Azure Services into ADF and understand how Azure services can be useful in designing ETL pipelines. The book will take you through the common errors that you may encounter while working with ADF and show you how to use the Azure portal to monitor pipelines. 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 as the main ETL and orchestration tool for your data warehouse or data platform projects.

Loading data to Azure Synapse Analytics using bulk load

Azure Synapse workspaces allow users to simply load data into a SQL pool with minimum mouse clicks. In this recipe, you will learn how to do this.

Getting ready

You need to have created an Azure Synapse workspace and a SQL pool, and Azure Data Lake Storage Gen2 should be linked to that workspace. The Flights dataset (or any other dataset) should be uploaded to your storage.

How to do it…

  1. Open the Azure Synapse workspace (also known as Synapse Studio).
  2. Click on the Data tab on the left side of your screen.
  3. Expand your SQL pool and click on Actions to the right of Tables. Select New SQL script | New table:
