  /**
   * Annotates an {@link Entity} to indicate which properties should be considered 'transient',
   * meaning that they should not be mapped to any column (neither during reads nor writes).
   *
   * <p>Example:
   *
   * <pre>
   * &#64;TransientProperties({"notAColumn", "x"})
   * &#64;Entity
   * public class Product {
   *   &#64;PartitionKey private UUID id;
   *   private String description;
   *   // these columns are not included because their names are specified in &#64;TransientProperties
   *   private int notAColumn;
   *   private int x;
   *   ...
   * }
   * </pre>
   *
   * <p>This annotation is an alternative to using the {@link Transient} annotation on a field or
   * getter. It is useful in cases where this annotation may be specified on a parent class where
   * implementing classes will share a common configuration without needing to explicitly annotate
   * each property with a {@link Transient} annotation.
