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.

Summary

In this chapter, we have applied the concepts learned previously to create and connect to Azure Databricks resources to store our data, such as ADLS Gen2, AWS S3, and Azure Blob storage. We have also learned how to ingest data from the storage to a Spark dataframe, transform it using Spark methods or using SQL scripts, and then persist the data into tables. Finally, we have seen how to schedule our jobs with Azure Databricks jobs, and how to create a pipeline in ADF and trigger it using a defined variable.

In the next chapter, we will learn about Azure Delta Lake and how to use it to create reliable ETL pipelines using Azure Databricks.
