In-Memory Analytics with Apache Arrow

By: Matthew Topol

Overview of this book

Apache Arrow is designed to accelerate analytics and allow the exchange of data across big data systems easily. In-Memory Analytics with Apache Arrow begins with a quick overview of the Apache Arrow format, before moving on to helping you to understand Arrow’s versatility and benefits as you walk through a variety of real-world use cases. You'll cover key tasks such as enhancing data science workflows with Arrow, using Arrow and Apache Parquet with Apache Spark and Jupyter for better performance and hassle-free data translation, as well as working with Perspective, an open source interactive graphical and tabular analysis tool for browsers. As you advance, you'll explore the different data interchange and storage formats and become well-versed with the relationships between Arrow, Parquet, Feather, Protobuf, Flatbuffers, JSON, and CSV. In addition to understanding the basic structure of the Arrow Flight and Flight SQL protocols, you'll learn about Dremio’s usage of Apache Arrow to enhance SQL analytics and discover how Arrow can be used in web-based browser apps. Finally, you'll get to grips with the upcoming features of Arrow to help you stay ahead of the curve. By the end of this book, you will have all the building blocks to create useful, efficient, and powerful analytical services and utilities with Apache Arrow.

Swimming in data with Dremio Sonar

The roots of Arrow can be found in the ValueVector objects from the Apache Drill project, a SQL query engine for Hadoop, NoSQL, and cloud storage. Dremio Sonar was originally built out of Apache Drill and Dremio's founders co-created Arrow. Arrow is used by Dremio Sonar as the internal memory representation for its query and calculation engine, which helps power its performance. Since its inception, Dremio's engineers have made many contributions to the Arrow project resulting in significant innovations. First, let's look at the architecture used and where Arrow fits in.

Clarifying Dremio Sonar's architecture

As a distributed query engine, Dremio Sonar can be deployed in many different environments and scenarios. However, at its core, it has a pretty simple architecture, as shown in Figure 9.1. Being distributed, it can scale horizontally by increasing the number of Coordinators and Executors that handle the planning and...
