Learn Azure Synapse Data Explorer

By: Pericles (Peri) Rocha

Overview of this book

Large volumes of data are generated daily from applications, websites, IoT devices, and other free-text, semi-structured data sources. Azure Synapse Data Explorer helps you collect, store, and analyze such data, and work with other analytical engines, such as Apache Spark, to develop advanced data science projects and maximize the value you extract from data. This book offers a comprehensive view of Azure Synapse Data Explorer, exploring not only the core scenarios of Data Explorer but also how it integrates within Azure Synapse. From data ingestion to data visualization and advanced analytics, you’ll learn to take an end-to-end approach to maximize the value of unstructured data and drive powerful insights using data science capabilities. With real-world usage scenarios, you’ll discover how to identify key projects where Azure Synapse Data Explorer can help you achieve your business goals. Throughout the chapters, you'll also find out how to manage big data as part of a software as a service (SaaS) platform, as well as tune, secure, and serve data to end users. By the end of this book, you’ll have mastered the big data life cycle and you'll be able to implement advanced analytical scenarios from raw telemetry and log data.

Creating a Power BI report

To make this flow easier to understand, let’s create a new report and see how we can work with it in Azure Synapse Studio. Proceed with the following steps:

  1. Launch Power BI Desktop. If you haven’t installed it already, please refer to the Technical requirements section at the beginning of this chapter.
  2. You will see a window with resources to help you get started with Power BI. Select Get data.
  3. In the Get Data window, pick Azure from the left-hand side and then Azure Data Explorer (Kusto), as illustrated in Figure 7.1.

Even though this connector refers to the standalone service Azure Data Explorer, the same connector can be used to access Data Explorer pools in Azure Synapse. Later, we will create a different connection using the Azure Synapse Analytics SQL connector.

When you are ready, click on the Connect button:
