Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions (Addison-Wesley Signature Series (Fowler))

The sender can send all of the messages in a sequence using a single transaction. This way, none of the messages will be delivered until all of them have been sent. Likewise, a receiver may wish to use a single transaction to receive the messages so that it does not truly consume any of the messages until it receives all of them. If any of the messages in the sequence are missing, the receiver can choose to roll back the transaction so that the messages can be consumed later. In many messaging system implementations, if a sequence of messages is sent in one transaction, the messages will be received in the order they are sent, which simplifies the receiver’s job of putting the data back together.
