Hands-On Data Warehousing with Azure Data Factory

By: Christian Cote, Michelle Gutzait, Giuseppe Ciaburro

Overview of this book

ETL is one of the essential techniques in data processing. Given data is everywhere, ETL will always be the vital process to handle data from different sources. Hands-On Data Warehousing with Azure Data Factory starts with the basic concepts of data warehousing and ETL process. You will learn how Azure Data Factory and SSIS can be used to understand the key components of an ETL solution. You will go through different services offered by Azure that can be used by ADF and SSIS, such as Azure Data Lake Analytics, Machine Learning and Databrick’s Spark with the help of practical examples. You will explore how to design and implement ETL hybrid solutions using different integration services with a step-by-step approach. Once you get to grips with all this, you will use Power BI to interact with data coming from different sources in order to reveal valuable insights. By the end of this book, you will not only learn how to build your own ETL solutions but also address the key challenges that are faced while building them.

Chapter 6. Introduction to Azure Databricks

So far in this book, we have seen that ETL can be done on-premises with an existing SSIS implementation. For cloud ETL, we used Azure Data Lake Analytics (ADLA). Sparks is one of the other major players when it comes to data integration on the cloud. Databricks is Sparks' latest addition in Azure services at the time of writing this book. It is meant to be simple to set up and use while delivering fast performance in a production environment.

In this chapter, we'll see how ADF can trigger a Databricks notebook run. Later in this book, we'll show how we can integrate this data into a Power BI report. This chapter introduces only the simple Databricks integration in ADF.
