About the Trigger Document Store
The trigger document store contains trigger queues in which Integration Server keeps locally published guaranteed documents awaiting processing. A document remains in trigger queue in the trigger document store until one of the following occurs:
Integration Server successfully executes the trigger service specified in the trigger condition satisfied by the document.
Integration Server discards the document because the document does not satisfy any conditions in the trigger.
Integration Server discards the document because it is a duplicate of one already processed by the trigger. This can occur only if the trigger is configured for exactly-once processing.
Integration Server cannot determine whether the trigger processed the document previously, assigns the document a status of In Doubt, and instructs the audit subsystem to log the document. This can occur only if the trigger is configured for exactly-once processing.
