How to Connect to Multiple Cassandra Keyspaces in Your Spring Boot Project

A keyspace in Cassandra is like a database in RDBMS.

I had to connect to different keyspaces in my project because one was for keeping encryption key parts and the tables were being watched with a security tool for access, the other keyspace had our project specific data.

My project was implemented with Spring Boot 2.3.5 RELEASE.

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.5.RELEASE</version>
</parent>

These were my other dependencies used for database operations implementation:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-cassandra</artifactId>
</dependency>

Firstly, I created a base configuration file class since I will need these common properties to connect to the database for each keyspace:

For encryption keyspace, I created another configuration file. As you can see, I declared the repository and model folders’ paths in “basePackages” and “getEntityBasePackages”:

This one is for the other keyspace (notice how “basePackages” and “getEntityBasePackages” values differ here):

I implemented my model, repository and service classes just like I would in a single keyspace one.

Now we are good to go!

Happy Coding!
