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.

Chapter 4: Managing Spark Clusters

A Spark cluster in Azure Databricks is probably the most important entity in the service. Although it is managed for us from the infrastructure end, we must understand the right cluster setting for an environment.

In this chapter, we will learn about the best practices to manage our Spark clusters to optimize our workloads. We will also learn about the Databricks managed resource group, which will help us understand how Azure Databricks is provisioned.

We will learn how to optimize costs associated with Spark clusters with pools and spot instances. In the end, we will learn about the essential components of the Spark UI that can help us debug and optimize queries.

In this chapter, we will cover the following topics:

  • Designing Spark clusters
  • Learning about Databricks managed resource groups
  • Learning about Databricks Pools
  • Using spot instances
  • Following the Spark UI
