Spring data cassandra (v3.3.1): how to add codec?

Question

I use spring-data-cassandra:3.3.1 and try to apply TimestampCodec. Documentation says that all codecs should be added through CodecRegistry, but says nothing about a way to access it.

I use config like this:

@Configuration
@EnableReactiveCassandraRepositories("com.example.repo")
public class CassandraConfig extends AbstractReactiveCassandraConfiguration

...but I don't understand how could I provide codecs.

Any ideas / examples?

You can override getSessionBuilderConfigurer inside your CassandraConfig class:

@Override
protected SessionBuilderConfigurer getSessionBuilderConfigurer() {
    return (sessionBuilder) -> sessionBuilder.addTypeCodecs(ExtraTypeCodecs.LOCAL_TIMESTAMP_UTC);
}
