Specifies the maximum number of unprocessed documents that can exist for this trigger in the trigger document store. (Each trigger has its own queue in the trigger document store on Integration Server.) The default is 10 documents.

Specifies the number of unprocessed documents that must remain in this trigger queue before the Integration Server retrieves more documents for the trigger. The default is 4 documents.

Specifies the maximum number of pending document acknowledgements for this trigger. A server thread places acknowledgements in the acknowledgement queue after it finishes executing the trigger service. Acknowledgements collect in the queue until the server returns them as a group to the sending resource. If the acknowledgement queue fills to capacity, the server blocks any server threads that attempt to add an acknowledgement to the queue. The blocked threads resume execution only after Integration Server empties the queue by returning the acknowledgements. The default is 1 acknowledgement.
