Apache Superset Quick Start Guide

Overview of this book

Apache Superset is a modern, open source, enterprise-ready business intelligence (BI) web application. With the help of this book, you will see how Superset integrates with popular databases like Postgres, Google BigQuery, Snowflake, and MySQL. You will learn to create real time data visualizations and dashboards on modern web browsers for your organization using Superset. First, we look at the fundamentals of Superset, and then get it up and running. You'll go through the requisite installation, configuration, and deployment. Then, we will discuss different columnar data types, analytics, and the visualizations available. You'll also see the security tools available to the administrator to keep your data safe. You will learn how to visualize relationships as graphs instead of coordinates on plain orthogonal axes. This will help you when you upload your own entity relationship dataset and analyze the dataset in new, different ways. You will also see how to analyze geographical regions by working with location data. Finally, we cover a set of tutorials on dashboard designs frequently used by analysts, business intelligence professionals, and developers.

We will be using Let's Encrypt ( a free, automated, and open certificate authority managed by the non-profit Internet Security Research Group (ISRG).

Secure Socket Layer (SSL) is a secure transport layer that can be used in any protocol; HTTPS is a common instance of it, that we will be implementing for our Superset web server.

Just like most other things, configuring SSL has OS level dependencies. First, we will install certbot, which is the free automated certificate service. It needs to verify our site first. It does this by doing some checks (which it calls challenges) in http://<url>/.well_known:

# Install certbot
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get install certbot
# Create .well_known directory
cd /var/www/html
mkdir .well_known

We also need to update the superset.conf file in the...
