How to block Cassandra from trying to connect automatically

Question

I have this project where I'm trying to connect to different DB types based on configuration. I have it working for Mongo and MySQL and switch by loading Beans by using @ConditionalOnProperty(name = "settings.data.source", havingValue = "mongodb")

Now I want to add Cassandra, but once I added the following dependency to my pom, it starts trying to connect to Cassandra nodes on localhost.

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

I want to have more control over when the Cassandra resources are loaded.

It doesn't try to connect automatically when I added Mongo dependencies:

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

Anyone familiar with this behavior? How can I control this? I don't always need a Cassandra connection...

You may disable Cassandra auto configuration,

@SpringBootApplication
@EnableAutoConfiguration(exclude={CassandraDataAutoConfiguration.class})
