How to map nested java objects in cassandra?

Mapping nested Java objects in Cassandra involves using the Object-Relational Mapping (ORM) framework such as Hibernate OGM or Spring Data Cassandra. These frameworks help in mapping Java classes to Cassandra tables and handle the conversion of nested objects to the desired Cassandra data types.

Here is an example of how you can map nested Java objects in Cassandra using Spring Data Cassandra:

1. Define your Java classes with nested objects that you want to map to Cassandra tables:

1
2
3
4
5
6
7

public class Address {
    private String street;
    private String city;
    private String zipCode;

    // getters and setters
}

1
2
3
4
5
6
7
8
9

@Table
public class User {
    @PrimaryKey
    private UUID userId;
    private String name;
    private Address address;

    // getters and setters
}

1. Create a Cassandra repository interface that extends CassandraRepository:

1
2
3
4

@Repository
public interface UserRepository extends CassandraRepository<User, UUID> {
    
}

1. Use the UserRepository interface to interact with the Cassandra database and perform CRUD operations on the User entity.

When you save a User object that contains nested Address object, it will be automatically mapped to the Cassandra tables by the Spring Data Cassandra framework.

Keep in mind that not all ORM frameworks fully support mapping nested objects in Cassandra, so make sure to research and choose a framework that fits your requirements. You may also need to manually handle the mapping of nested objects if your chosen framework does not support it out of the box.
