Interface CassandraRepository<T>

Type Parameters:

T - The type of the persistent entity.

All Superinterfaces:

CrudRepository<T,MapId>, Repository<T,MapId>, TypedIdCassandraRepository<T,MapId>

public interface CassandraRepository<T>
extends TypedIdCassandraRepository<T,MapId>

Basic Cassandra repository interface.

This interface uses MapId for the id type, allowing you to annotate entity fields or properties with @PrimaryKeyColumn. For a full discussion of this interface, including the use of custom primary key classes, see TypedIdCassandraRepository.

Steps to use this interface:

• Define your entity, including a field or property for each column, including those for partition and (optional) cluster columns.
• Annotate each partition & cluster field or property with @PrimaryKeyColumn
• Define your repository interface to be a subinterface of this interface, which uses a provided id type, MapId (implemented by BasicMapId).
• Whenever you need a MapId, you can use the static factory method BasicMapId.id() (which is convenient if you import statically) and the builder method MapId.with(String, Serializable) to easily construct an id.
• Optionally, entity class authors can have their entities implement MapIdentifiable, to make it easier and quicker for entity clients to get the entity's identity.
