Über dieses Buch
Get to grips with building and productionizing end-to-end big data solutions in Azure and learn best practices for working with large datasets
Key Features
- Integrate with Azure Synapse Analytics, Cosmos DB, and Azure HDInsight Kafka Cluster to scale and analyze your projects and build pipelines
- Use Databricks SQL to run ad hoc queries on your data lake and create dashboards
- Productionize a solution using CI/CD for deploying notebooks and Azure Databricks Service to various environments
Book Description
Azure Databricks is a unified collaborative platform for performing scalable analytics in an interactive environment. The Azure Databricks Cookbook provides recipes to get hands-on with the analytics process, including ingesting data from various batch and streaming sources and building a modern data warehouse.The book starts by teaching you how to create an Azure Databricks instance within the Azure portal, Azure CLI, and ARM templates. You'll work through clusters in Databricks and explore recipes for ingesting data from sources, including files, databases, and streaming sources such as Apache Kafka and EventHub. The book will help you explore all the features supported by Azure Databricks for building powerful end-to-end data pipelines. You'll also find out how to build a modern data warehouse by using Delta tables and Azure Synapse Analytics. Later, you'll learn how to write ad hoc queries and extract meaningful insights from the data lake by creating visualizations and dashboards with Databricks SQL. Finally, you'll deploy and productionize a data pipeline as well as deploy notebooks and Azure Databricks service using continuous integration and continuous delivery (CI/CD).By the end of this Azure book, you'll be able to use Azure Databricks to streamline different processes involved in building data-driven apps.
What you will learn
- Read and write data from and to various Azure resources and file formats
- Build a modern data warehouse with Delta Tables and Azure Synapse Analytics
- Explore jobs, stages, and tasks and see how Spark lazy evaluation works
