    // this can result in poor performance in a production application.

    // result in poor distribution of operations across nodes.

  // By default, the `table` object uses the `SafeIdempotentMutationPolicy`
  // which does not retry if any of the mutations fails and are
  // not-idempotent. In this example we simply print such failures, if any,
  // and ignore them otherwise.
