Problem
How can you provide a level of guarantee for a resource over a long-running business process?
Solution
Have a service provide a level of guarantee on resources for a limited time.
- Messages are sent to to the reservation service by the service consumer.
- Initial reservation request returns a reservation ID and an expiration timestamp.
- Service consumer confirms previous registered reservation by including a valid reservation ID.
- Expiry timestamp allows service to expire unconfirmed reservations after a given time period.
