Azure Data Engineering Cookbook

Overview of this book

Data engineering is one of the faster growing job areas as Data Engineers are the ones who ensure that the data is extracted, provisioned and the data is of the highest quality for data analysis. This book uses various Azure services to implement and maintain infrastructure to extract data from multiple sources, and then transform and load it for data analysis. It takes you through different techniques for performing big data engineering using Microsoft Azure Data services. It begins by showing you how Azure Blob storage can be used for storing large amounts of unstructured data and how to use it for orchestrating a data workflow. You'll then work with different Cosmos DB APIs and Azure SQL Database. Moving on, you'll discover how to provision an Azure Synapse database and find out how to ingest and analyze data in Azure Synapse. As you advance, you'll cover the design and implementation of batch processing solutions using Azure Data Factory, and understand how to manage, maintain, and secure Azure Data Factory pipelines. You’ll also design and implement batch processing solutions using Azure Databricks and then manage and secure Azure Databricks clusters and jobs. In the concluding chapters, you'll learn how to process streaming data using Azure Stream Analytics and Data Explorer. By the end of this Azure book, you'll have gained the knowledge you need to be able to orchestrate batch and real-time ETL workflows in Microsoft Azure.

Pausing or resuming a Synapse SQL pool using PowerShell

In an Azure Synapse SQL pool, the compute and storage are decoupled and are therefore charged separately. This means that if we aren't running any queries and are not using the compute, we can pause the Synapse SQL pool to save on compute cost. We'll still be charged for the storage.

A data warehouse is mostly used when it's to be refreshed with the new data or any computation needs to be performed to prepare the summary tables for the reports. We can save compute costs when it's not being used.

In this recipe, we'll learn how to pause and resume a Synapse SQL pool.

Getting ready

Before you start, log in to Azure from PowerShell. To do this, execute the following command and follow the instructions to log in to Azure:

Connect-AzAccount

You need a Synapse SQL pool to perform the steps in this recipe. If you don't have an existing Synapse SQL pool, you can create one using the steps...
