Description

Google Cloud Tasks queues support the TombstoneTtl parameter (https://cloud.google.com/tasks/docs/reference/rest/v2beta3/projects.locations.queues) which controls how soon a task with the same unique ID can be re-added to the queue. When using deduplication this parameter is pretty important. By default, the parameter is set to one hour hence deduplication prevents tasks with the same ID from being re-added to the queue for an hour. This is quite prohibitive and makes this feature significantly less useful.

New or Affected Resource(s)

• google_cloud_tasks_queue

Potential Terraform Configuration

Proposed config format:

resource "google_cloud_tasks_queue" "async_task_queue" {
    ...
    tombstone_ttl = "3s"
    ...
}

Currently, Terraform Provider Beta is using GA API for cloudtasks product. As we want to add support for tombstone_ttl field which is a beta-only field, we need to use Beta API. But, Beta API doesn't have appEngineRoutingOverride field which is available in GA API. Instead, the appEngineRoutingOverride field is inside of the appEngineHttpQueue field. I guess this might require schema changes (particularly for cloud_tasks_queue beta resource) that will be a breaking change.
