   * <p>The views returned by the {@code Table} methods {@link Table#column}, {@link
   * Table#columnKeySet}, and {@link Table#columnMap} have iterators that don't support {@code
   * remove()}. Otherwise, all optional operations are supported. Null row keys, columns keys, and
   * values are not supported.
   *
   * <p>Lookups by row key are often faster than lookups by column key, because the data is stored

The `HeroUpdate` *data model* is somewhat special, it has **all the same fields** that would be needed to create a new hero, but all the fields are **optional** (they all have a default value). This way, when you update a hero, you can send just the fields that you want to update.

Das `HeroUpdate`-*Datenmodell* ist etwas Besonderes, es hat **die selben Felder**, die benötigt werden, um einen neuen Helden zu erstellen, aber alle Felder sind **optional** (sie haben alle einen Defaultwert). Auf diese Weise, wenn Sie einen Helden aktualisieren, können Sie nur die Felder senden, die Sie aktualisieren möchten.
