val listByAuthor = withSchema { (authorId: UUID) =>
      cql"""
         SELECT post_id, author_name, reviewer_name, post_title, post_rating, post_tags
         FROM test.posts
         WHERE author_id = $authorId
         ORDER BY post_id DESC ;
       """
        .prepared
        .executeAsync
        .as(Post)
