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.

Summary

In this chapter, we learned about batch and stream processing. We started with the differences between the two processing paradigms and then progressed to mounting Azure storage on Databricks. This was followed by a deep dive into batch processing and Spark transformations. We also looked at a real-world example of a batch ETL process, where we read data in Parquet, transformed it, and wrote it back to Delta Lake.

Last but not the least, we also learned about Spark Structured Streaming, with an example. Spark Structured Streaming is ideal for reading and writing data in real time. Several downstream applications require real-time data, such as real-time dashboards.

In the next chapter, we will learn about machine learning and graph processing in Databricks. We will also go through plenty of examples to aid the learning process.
