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.

Learning about graph analysis in Databricks

Graph analysis is the study of graphs to help deliver actionable insights and make decisions based on relationships between entities. A graph is a visual depiction of data with vertices and edges that helps in establishing relationships between entities. Let's learn more about this with an example, as follows:

Figure 3.7 – An example of a graph

In the preceding screenshot, we can see an example of a typical graph. Here, the entities in the circles are called vertices. Each vertex is treated as an object that has its own properties called attributes. Every vertex has a relationship with another vertex in a graph. This is called an edge.

For instance, let's say vertex a represents a person named Mark and vertex b represents a person named Thomas. Mark has an attribute that states he is 32 years old. Similarly, Thomas is 30 years old. An edge between these two vertices states friend. This defines...
