EventTrigger(mapping=None, *, ignore_unknown_fields=False, **kwargs)Describes EventTrigger, used to request events be sent from another service.
Attributes
| Name | Description |
| event_type |
str
Required. The type of event to observe. For example: ``providers/cloud.storage/eventTypes/object.change`` and ``providers/cloud.pubsub/eventTypes/topic.publish``. Event types match pattern ``providers/*/eventTypes/*.*``. The pattern contains: 1. namespace: For example, ``cloud.storage`` and ``google.firebase.analytics``. 2. resource type: The type of resource on which event occurs. For example, the Google Cloud Storage API includes the type ``object``. 3. action: The action that generates the event. For example, action for a Google Cloud Storage Object is 'change'. These parts are lower case. |
| resource |
str
Required. The resource(s) from which to observe events, for example, ``projects/_/buckets/myBucket``. Not all syntactically correct values are accepted by all services. For example: 1. The authorization model must support it. Google Cloud Functions only allows EventTriggers to be deployed that observe resources in the same project as the ``CloudFunction``. 2. The resource type must match the pattern expected for an ``event_type``. For example, an ``EventTrigger`` that has an ``event_type`` of "google.pubsub.topic.publish" should have a resource that matches Google Cloud Pub/Sub topics. Additionally, some services may support short names when creating an ``EventTrigger``. These will always be returned in the normalized "long" format. See each *service's* documentation for supported formats. |
| service |
str
The hostname of the service that should be observed. If no string is provided, the default service implementing the API will be used. For example, ``storage.googleapis.com`` is the default for all event types in the ``google.storage`` namespace. |
| failure_policy |
google.cloud.functions_v1.types.FailurePolicy
Specifies policy for failed executions. |
