# Tâches d'arrière-plan { #background-tasks }

Vous pouvez définir des tâches d'arrière-plan qui seront exécutées après avoir retourné une réponse.

Ceci est utile pour les opérations qui doivent avoir lieu après une requête, mais où le client n'a pas réellement besoin d'attendre que l'opération soit terminée pour recevoir une réponse.

Cela comprend, par exemple :

* Les notifications par email envoyées après l'exécution d'une action :

                plan.then(segment);
            }

            // Create plan, setup and teardown
            for (MavenProject project : plan.getAllProjects().keySet()) {
                BuildStep pplan = new BuildStep(PLAN, project, null);
                pplan.status.set(PLANNING); // the plan step always need planning

Ancak aynı **FastAPI** app’i içindeki değişkenlere ve objelere erişmeniz gerekiyorsa veya küçük arka plan görevleri (email bildirimi göndermek gibi) yapacaksanız, doğrudan `BackgroundTasks` kullanabilirsiniz.
