Cloud Scale Analytics with Azure Data Services

By: Patrik Borosch

Overview of this book

Azure Data Lake, the modern data warehouse architecture, and related data services on Azure enable organizations to build their own customized analytical platform to fit any analytical requirements in terms of volume, speed, and quality. This book is your guide to learning all the features and capabilities of Azure data services for storing, processing, and analyzing data (structured, unstructured, and semi-structured) of any size. You will explore key techniques for ingesting and storing data and perform batch, streaming, and interactive analytics. The book also shows you how to overcome various challenges and complexities relating to productivity and scaling. Next, you will be able to develop and run massive data workloads to perform different actions. Using a cloud-based big data-modern data warehouse-analytics setup, you will also be able to build secure, scalable data estates for enterprises. Finally, you will not only learn how to develop a data warehouse but also understand how to create enterprise-grade security and auditing big data programs. By the end of this Azure book, you will have learned how to develop a powerful and efficient analytical platform to meet enterprise needs.

Programming with Synapse Spark pools

Now that you understand how to provision a Spark pool and how resources are used, let's proceed and examine the different interfaces that you can use to program against a Spark instance.

Understanding Synapse Spark notebooks

Notebooks are the rising star when it comes to interactive data analysis. They offer a step-by-step programming experience where you receive immediate feedback for single code steps. You can enter one line or a block of code into a cell and you can run it directly using an available Spark instance and have the results displayed below the cell.

To create a new notebook, you want to navigate to the Develop hub in Synapse Studio. Here, you can hit the + icon in the navigation pane (next to the word Develop) and select Notebook (Figure 6.11):
