Abstract

Message intermediation for multiple service instances, while allowing the service instance to control whether messages are processed under a transaction. The message intermediator chooses to dispatch messages among different backend service instances based on any routing rules. The message intermediator performs a peek-lock of message from a forward-end queue, and assigns the message to a service instance. The message is provided into a backward-end queue specific to the assigned service instance. The service instance may then process the message, perhaps under a transaction created at the service instance. Upon completion of processing, the message is deleted in the back-end queue, which causes the forward-end queue to delete the message under the same transaction created by the service instance. Whether or not this deletion at the forward-end is committed or rolled back depends on whether the transaction created at the service instance is committed or rolled back.
