10 minutes, Beginner, Start Building

This application uses Spring Data Cassandra and DataStax Astra DB to build a REST API for a backend service that interacts with products and orders.

Objectives

  • Run a REST API that connects to DataStax Astra DB

How this works

We're using Spring Data Cassandra and Datastax Astra DB to build a REST API that stores Products and Orders.

Get Started

To build and play with this app, follow the build instructions that are located here: https://github.com/DataStax-Examples/spring-data-starter

Running Spring Data Cassandra REST API

Follow the instructions below to get started.

Prerequisites

Let's do some initial setup by creating a serverless(!) database.

DataStax Astra

  1. Create a DataStax Astra account if you don't already have one: image

  2. On the home page. Locate the button Create Database image

  3. Locate the Get Started button to continue image

  4. Define a database name, keyspace name and select a database region, then click create database. image

  5. Your Astra DB will be ready when the status will change from Pending to Active 💥💥💥 image

  6. After your database is provisioned, we need to generate an Application Token for our App. Go to the Settings tab in the database home screen. image

  7. Select Admin User for the role for this Sample App and then generate the token. Download the CSV so that we can use the credentials we need later. image

  8. After you have your Application Token, head to the database connect screen and select the driver connection that we need. Go ahead and download the Secure Bundle for the driver. image

  9. Make note of where to use the Client Id and Client Secret that is part of the Application Token that we generated earlier. image

Github

  1. Click Use this template at the top of the GitHub Repository: image

  2. Enter a repository name and click 'Create repository from template': image

  3. Clone the repository: image

🚀 Getting Started Paths:
