Interface CassandraRepository<T,K>

Type Parameters:
T - the entity type
K - the primary key type of the entity
All Superinterfaces:
jakarta.data.repository.BasicRepository<T,K>, jakarta.data.repository.CrudRepository<T,K>, jakarta.data.repository.DataRepository<T,K>, org.eclipse.jnosql.mapping.NoSQLRepository<T,K>
public interface CassandraRepository<T,K> extends org.eclipse.jnosql.mapping.NoSQLRepository<T,K>
A Cassandra-specific extension of NoSQLRepository, providing repository-style data access. This interface extends the generic NoSQLRepository, allowing seamless integration with Cassandra's schema-less NoSQL database model while leveraging query capabilities provided by CQL.

Example usage:


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

     @CQL("SELECT * FROM users WHERE username = :username")
     List<User> findByUsername(@Param("username") String username);

     @CQL("DELETE FROM users WHERE id = :id")
     void deleteById(@Param("id") String id);
 }
