Distributed Data Systems with Azure Databricks

By: Alan Bernardo Palacio

Overview of this book

Microsoft Azure Databricks helps you to harness the power of distributed computing and apply it to create robust data pipelines, along with training and deploying machine learning and deep learning models. Databricks' advanced features enable developers to process, transform, and explore data. Distributed Data Systems with Azure Databricks will help you to put your knowledge of Databricks to work to create big data pipelines. The book provides a hands-on approach to implementing Azure Databricks and its associated methodologies that will make you productive in no time. Complete with detailed explanations of essential concepts, practical examples, and self-assessment questions, you’ll begin with a quick introduction to Databricks core functionalities, before performing distributed model training and inference using TensorFlow and Spark MLlib. As you advance, you’ll explore MLflow Model Serving on Azure Databricks and implement distributed training pipelines using HorovodRunner in Databricks. Finally, you’ll discover how to transform, use, and obtain insights from massive amounts of data to train predictive models and create entire fully working data pipelines. By the end of this MS Azure book, you’ll have gained a solid understanding of how to work with Databricks to create and manage an entire big data pipeline.

Chapter 4: Delta Lake with Azure Databricks

In this chapter, we will learn how to make use of Azure Databricks by showing how easy it is to work with Delta tables, as well as how to process data and integrate different solutions in Azure Databricks. We will begin by introducing Delta Lake and how to ingest data with it using either using partner integrations, the COPY INTO command, and the Azure Databricks Auto Loader. Then, we'll show you how to process the data once it has been loaded, as well as how we can use advance features in order to process and optimize ETLs that rely on streams of data.

We will learn how to store and process data efficiently using Delta by covering the following topics:

  • Introducing Delta Lake
  • Ingesting data using Delta Lake
  • Batching table reads and writes in queries
  • Querying past states of a table
  • Streaming table read and writes
