Overview of this book

The famous quote 'Data is the new oil' seems more true every day as the key to most organizations' long-term success lies in extracting insights from raw data. One of the major challenges organizations face in leveraging value out of data is building performant data engineering pipelines for data visualization, ingestion, storage, and processing. This second edition of the immensely successful book by Ahmad Osama brings to you several recent enhancements in Azure data engineering and shares approximately 80 useful recipes covering common scenarios in building data engineering pipelines in Microsoft Azure. You’ll explore recipes from Azure Synapse Analytics workspaces Gen 2 and get to grips with Synapse Spark pools, SQL Serverless pools, Synapse integration pipelines, and Synapse data flows. You’ll also understand Synapse SQL Pool optimization techniques in this second edition. Besides Synapse enhancements, you’ll discover helpful tips on managing Azure SQL Database and learn about security, high availability, and performance monitoring. Finally, the book takes you through overall data engineering pipeline management, focusing on monitoring using Log Analytics and tracking data lineage using Azure Purview. By the end of this book, you’ll be able to build superior data engineering pipelines along with having an invaluable go-to guide.

Triggering a pipeline in Azure Data Factory

An Azure Data Factory pipeline can be triggered manually, scheduled, or triggered by an event. In this recipe, we’ll configure an event-based trigger to run the pipeline that we created in the previous recipe whenever a new file is uploaded to the Data Lake Store.

Getting ready

Before you start, perform the following steps:

  • Log in to the Azure portal via PowerShell. To do this, execute the following command and follow the instructions to log in to Azure:
    Connect-AzAccount
  • Go to https://portal.azure.com and log in using your Azure credentials.
  • Create the ControlFlowActivities pipeline, as specified in the previous recipe, if you haven’t created it already.

How to do it…

To create the trigger, follow these steps:

  1. The event trigger requires the eventgrid resource to be registered in the subscription. To do that, execute the following PowerShell command:
    Register-AzResourceProvider -ProviderNamespace...
