   * Textual features. some examples would be the brand/maker of a product, or
   * country of a customer. Numerical features. Some examples would be the
   * height/weight of a product, or age of a customer.
   * For example: `{ "vendor": {"text": ["vendor123", "vendor456"]},
   * "lengths_cm": {"numbers":[2.3, 15.4]}, "heights_cm": {"numbers":[8.1, 6.4]}
   * }`.
   * This field needs to pass all below criteria, otherwise an INVALID_ARGUMENT
   * error is returned:
   * * Max entries count: 200.
   * * The key must be a UTF-8 encoded string with a length limit of 128
   *   characters.
   * * For indexable attribute, the key must match the pattern:
   *   `[a-zA-Z0-9][a-zA-Z0-9_]*`. For example, `key0LikeThis` or
   *   `KEY_1_LIKE_THIS`.
   * * For text attributes, at most 400 values are allowed. Empty values are not
   *   allowed. Each value must be a non-empty UTF-8 encoded string with a
   *   length limit of 256 characters.
   * * For number attributes, at most 400 values are allowed.
