- Choosing an erasure set for the object is decided during `PutObject()`, object names are used to find the right erasure set using the following pseudo code.

```go
// hashes the key returning an integer.
func sipHashMod(key string, cardinality int, id [16]byte) int {
        if cardinality <= 0 {
                return -1
        }
        sip := siphash.New(id[:])
        sip.Write([]byte(key))
        return int(sip.Sum64() % uint64(cardinality))

   *
   * @param event the callback to execute on {@link #dispatch}
   * @param label a description of the event to use in the case of an error
   */
  public void enqueue(Event<L> event, String label) {
    enqueueHelper(event, label);
  }

  private void enqueueHelper(Event<L> event, Object label) {

* La API verifica ese `username` y `password`, y responde con un "token" (no hemos implementado nada de esto aún).
    * Un "token" es solo un string con algún contenido que podemos usar luego para verificar a este usuario.
    * Normalmente, un token se establece para que expire después de algún tiempo.
        * Así que, el usuario tendrá que volver a iniciar sesión más adelante.

Sie können diese Funktion anpassen. Sie nimmt eine `APIRoute` und gibt einen String zurück.

Hier verwendet sie beispielsweise den ersten Tag (Sie werden wahrscheinlich nur einen Tag haben) und den Namen der *Pfadoperation* (den Funktionsnamen).
