By: Anirudh Kala, Anshul Bhatnagar, Sarthak Sarbahi

Overview of this book

Databricks is an industry-leading, cloud-based platform for data analytics, data science, and data engineering supporting thousands of organizations across the world in their data journey. It is a fast, easy, and collaborative Apache Spark-based big data analytics platform for data science and data engineering in the cloud. In Optimizing Databricks Workloads, you will get started with a brief introduction to Azure Databricks and quickly begin to understand the important optimization techniques. The book covers how to select the optimal Spark cluster configuration for running big data processing and workloads in Databricks, some very useful optimization techniques for Spark DataFrames, best practices for optimizing Delta Lake, and techniques to optimize Spark jobs through Spark core. It contains an opportunity to learn about some of the real-world scenarios where optimizing workloads in Databricks has helped organizations increase performance and save costs across various domains. By the end of this book, you will be prepared with the necessary toolkit to speed up your Spark jobs and process your data more efficiently.

Mounting Azure Data Lake in Databricks

Azure Data Lake (storage account) is a limitless data lake service managed by Microsoft. It allows the storage and analysis of big data of all forms: structured, semi-structured, and unstructured. It is built to accommodate big data analytics by integrating with Hadoop and Spark. We will be using Azure Data Lake quite often in this book. So, it is important for us to learn its integration with Azure Databricks.

Creating an Azure Data Lake instance

Now, we will create an Azure Data Lake instance and use it as our primary data store in the Azure environment:

  1. Go to Azure's website (portal.azure.com) and sign in to the portal. Open an existing resource group, then click on Create and then on Marketplace. Search for Storage account. The following window opens up:
