What correlation is there between datastore and task queue downtime?
(I'd like to use the task queue to defer some operations in the case of datastore downtime.)
回答1:
The Task Queue should be generally more durable than the datastore, as it's a simpler system, but there's no guarantee that they can't both experience a simultaneous outage.
