#### Do-stuff-later pool

Sometimes there's an action required like calling the application layer or responding to a ping, and the thread discovering the action is not the thread that should do the work. We enqueue a runnable on this executor and it gets handled by one of the executor's threads.

### Locks

 *
 * <p>In some cases, when speed is more important than code readability, it may be faster simply to
 * treat primitive {@code long} values as unsigned, using the methods from {@link UnsignedLongs}.

## Response mit beliebigem `dict`

Sie könne auch eine Response deklarieren, die ein beliebiges `dict` zurückgibt, bei dem nur die Typen der Schlüssel und der Werte bekannt sind, ohne ein Pydantic-Modell zu verwenden.

Das ist nützlich, wenn Sie die gültigen Feld-/Attribut-Namen von vorneherein nicht wissen (was für ein Pydantic-Modell notwendig ist).
