• essentially a POST request to write to the server

mutation CreateReviewForEpisode($ep: Episode!, $review: ReviewInput!) {
  createReview(episode: $ep, review: $review) {
    stars
    commentary
  }
}

Warning

While query fields are executed in parallel, mutation fields run in series, one after the other.

If two mutation requests are sent at the same time, the first one will always finish before the second one!
