DELIVERY_REQUIREMENT_UNSPECIFIED
Default value. This value is unused.
DELIVER_IMMEDIATELY
The server does not wait for a published message to be successfully written to storage before delivering it to subscribers.
DELIVER_AFTER_STORED
The server will not deliver a published message to subscribers until the message has been successfully written to storage. This will result in higher end-to-end latency, but consistent delivery.
