    // this can result in poor performance in a production application.
    // Since rows are stored in sorted order by key, sequential keys can
    // 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.
  std::cerr << "The following mutations failed and were not retried:\n";
