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.

Implementing an auto-failover group for an Azure SQL database using PowerShell

An auto-failover group allows a group of databases to fail to a secondary server in another region if the SQL database service in the primary region fails. Unlike active geo-replication, the secondary server should be in a different region from the primary. The secondary databases can be used to offload read workloads. The failover can be manual or automatic.

In this recipe, we’ll create an auto-failover group, add databases to the auto-failover group, and perform a failover to the secondary server.

Getting ready

In a new PowerShell window, execute the Connect-AzAccount command and follow the steps to log in to your Azure account.

You will need an existing Azure SQL database for this recipe. If you don’t have one, create an Azure SQL database by following the steps mentioned in the Provisioning and connecting to an Azure SQL database using PowerShell recipe of Chapter 5, Configuring...
