Optimizing Databricks Workloads

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 2: Batch and Real-Time Processing in Databricks

Azure Databricks is capable of processing batch and real-time big data workloads using Apache Spark™. As data engineers, it is important to master these workloads for building real-world use cases. A batch load generally refers to an ETL (Extract, Transform, Load) or ELT (Extract, Load, Transform) process where large chunks of data get copied from a source to a sink. This type of workload can take time to process, ranging from minutes to hours, whereas real-time processing works with a much smaller latency (that is, seconds or even milliseconds).

When it comes to Databricks, there are different ways to process batch and real-time workloads. In this chapter, we will discuss the approaches to build and run these workloads. The topics covered in this chapter are as follows:

  • Differentiating batch versus real-time processing
  • Mounting Azure Data Lake in Databricks
  • Working with batch processing
  • Batch ETL...
