   * Benchmarks for {@link GetterBasedSchemaProvider} on reading / writing fields based on {@link
   * GetterBasedSchemaProvider#toRowFunction(TypeDescriptor) toRowFunction} / {@link
   * GetterBasedSchemaProvider#fromRowFunction(TypeDescriptor) fromRowFunction}.
   *
   * <p>Each benchmark method invocation, depending on {@link RowBundle#action}, either reads a single
   * field of a bundle of {@link RowBundle#bundleSize n} rows using the corresponding getter via
   * {@link RowWithGetters#getValue} or writes that field using the corresponding setter to a new
   * object instance.
   *
   * <p>Rows are created upfront and provided as JMH {@link State} to exclude initialization costs
   * from the measurement.
   *
   * <ul>
   *   <li>The score doesn't reflect read / write access only, measurement includes iterating over a
   *       large number of rows.
   *   <li>All rows contain just a single field. Nevertheless it is tricky to compare scores between
   *       different benchmarks: nested structures are read recursively and collections / maps are
   *       iterated through.
