/**
 * Basic Cassandra repository interface.
 * <p/>
 * This interface uses {@link MapId} for the id type, allowing you to annotate entity fields or properties with
 * {@link PrimaryKeyColumn @PrimaryKeyColumn}. For a full discussion of this interface, including the use of custom
 * primary key classes, see {@link TypedIdCassandraRepository}.
 * <p/>
 * Steps to use this interface:
 * <ul>
 * <li>Define your entity, including a field or property for each column, including those for partition and (optional)
 * cluster columns.</li>
 * <li>Annotate each partition & cluster field or property with {@link PrimaryKeyColumn @PrimaryKeyColumn}</li>
 * <li>Define your repository interface to be a subinterface of this interface, which uses a provided id type,
 * {@link MapId} (implemented by {@link BasicMapId}).</li>
 * <li>Whenever you need a {@link MapId}, you can use the static factory method {@link BasicMapId#id()} (which is
 * convenient if you import statically) and the builder method {@link MapId#with(String, Object)} to easily construct an
 * id.</li>
 * <li>Optionally, entity class authors can have their entities implement {@link MapIdentifiable}, to make it easier and
 * quicker for entity clients to get the entity's identity.</li>
 * </ul>
 *
 * @param <T> The type of the persistent entity.
