Modifications du statut d'exécution d'EventBridge for Amazon SWF
Vous utilisez Amazon EventBridge pour répondre aux modifications d'état ou aux événements d'unAWSressource. Lorsqu'Amazon SWF émet un événement, il accède toujours au bus d'événement EventBridge par défaut de votre compte. Vous pouvez créer une règle pour les événements, l'associer au bus d'événement par défaut et spécifier une action cible à effectuer lorsqu'EventBridge reçoit un événement correspondant à la règle. De cette façon, vous pouvez surveiller vos flux de travail sans avoir à interroger constamment à l'aide de laGetWorkflowExecutionHistory
API. En fonction des modifications apportées aux exécutions de flux de travail, vous pouvez utiliser une cible EventBridge pour appelerAWS Lambda, publiez des messages dans des rubriques Amazon Simple Notification Service (Amazon SNS), et plus encore.
Vous pouvez voir le contenu complet d'un événement de changement d'état d'exécution à l'aide deDescribeWorkflowExecution
.
Pour de plus amples informations, veuillez consulter le Guide de l'utilisateur Amazon EventBridge.

: l'ID d'événement affiché par GetWorkflowExecutionHistory. -
workflowExecutionDetail
: l'état du flux de travail lorsque l'événement a été émis. -

Exemples d'événements Amazon SWF
Voici des exemples d'envoi d'événements Amazon SWF à EventBridge :
Rubriques
Dans chaque cas, la section detail
des données de l'événement fournit les mêmes informations que l'API DescribeWorkflowExecution
. LeexecutionStatus
indique l'état de l'exécution au moment où l'événement a été envoyé, soitOPEN
ouCLOSED
.
