The document outlines how to create a user profile using DataStax Astra as a backend for client applications, emphasizing its cloud-based Cassandra service. It details features such as high availability, scalability, and the importance of defining primary keys for effective data querying. Additionally, it includes examples and resources for further learning on Cassandra data modeling and a user profile data model.
Apache Cassandra Lunch #71: Creating a User Profile Using DataStax Astra and React
- 1. Version 1.0 Creating a User Profile Using DataStax Astra We will discuss how DataStax Astra can be used as a back- end for a client application and demonstrate connecting to a DataStax Astra database to store user profile details and changes. Josh Barnes Jr. Engineer @Anant
- 2. DataStax Astra ● Cassandra in the cloud. - Highly Available, Horizontal scaling, distributed. ● Astra provides the ability to use Cassandra-as-a-Service ● “DataStax Astra DB includes guardrails and sets limits to ensure good practices, foster availability, and promote optimal configurations for your databases.” ○ https://docs.datastax.com/en/astra/docs/datastax-astra-database-limits.html ○ Eliminate the overhead to install, operate, and scale Cassandra ● Free to get started. ● Out-of-the-box REST and GraphQL endpoints and browser CQL shell ● Powered by DataStax’s open-source Kubernetes Operator for Cassandra ● Deploy on AWS, GCP, or Microsoft Azure and keep compatibility with open-source Cassandra.
- 3. Cassandra Data Modeling ● Joins are not allowed. ● Tables created on a per query basis. ○ This means we need to think about the data we want to store and retrieve before we create our tables. ● Primary Keys definitions determine how data will be queried.

- 4. User Profile Data Model ● Query to create and a user profile by capturing a username, password, first name, last name, and email. ● A query by username to verify a password. ● A query by a user id to get profile information.
