# Tâches d'arrière-plan

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 :

fun createQuickFeedbackTasks() {
    val testType = TestType.CROSSVERSION
    val defaultExecuter = "embedded"
    val prefix = testType.prefix
    testType.executers.forEach { executer ->
        val taskName = "$executer${prefix.capitalize()}Test"
        val testTask = createTestTask(taskName, executer, sourceSet, testType) {
            this.setSystemPropertiesOfTestJVM("latest")
            this.systemProperties["org.gradle.integtest.crossVersion"] = "true"

            runCalled.getAndIncrement();
          }
        },
        directExecutor());
    Runnable execute =
        new Runnable() {
          @Override
          public void run() {
            list.execute();
          }
        };
    Thread thread1 = new Thread(execute);
    Thread thread2 = new Thread(execute);
    thread1.start();
    thread2.start();
    assertEquals(0, runCalled.get());

* Added a 'kubeadm config migrate' command to convert old API types to their newer counterparts in the new, supported API types. This is just a client-side tool; it just executes locally without requiring a cluster to be running, operating in much the same way as a Unix pipe that upgrades config files.
