Subscription
A subscription to a topic.
Messages are delivered to the subscription’s queue and retried up to a maximum number of times. If a message cannot be delivered after the maximum number of retries it is moved to the dead letter queue.
The dead letter queue is a directory of JSON files containing the serialized message.
Messages remain in the dead letter queue until they are removed manually.
