Par exemple, au lieu d’utiliser la même session de base de données, vous créeriez une nouvelle session de base de données à l’intérieur de la tâche d’arrière‑plan, et vous obtiendriez les objets depuis la base de données en utilisant cette nouvelle session. Puis, au lieu de passer l’objet obtenu depuis la base de données en paramètre à la fonction de tâche d’arrière‑plan, vous passeriez l’identifiant (ID) de cet objet et vous obtiendriez...
