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.

Arrow in the browser using JavaScript

One of the most common ways to currently deploy an application to consumers is by developing a web application. You can provide an application intended for mobile phones, tablets, or laptop/desktop browsers all in one location. When it comes to building modern interactive applications on the web, you can be sure that JavaScript and/or TypeScript are going to be involved somewhere. Now that we've covered some examples of services and systems utilizing Arrow, we'll cover a couple of projects that are leveraging Arrow front-and-center right in the browser.

Gaining a little perspective

In Chapter 3, Data Science with Apache Arrow, we briefly touched on a library named Perspective in the context of a widget for Jupyter notebooks. Perspective was originally developed at J.P. Morgan and was then open-sourced under the Apache Open Source License 2.0 through the Fintech Open Source Foundation (FINOS). Perspective is written in C++ and compiled...
