    Idea / RFE Review. Apologies for the length of time this idea has been in the status of Uncommitted Candidate / Future Consideration. The AggregateReply node does not have a node property to provide additional instances for dealing with completed aggregations ... although the existing operational model for this node provides a performance optimization which causes the same thread which delivers the final message which completes the aggregation to then be used to carry the aggregated data downstream to later nodes downstream in the flow. This means that if there are multiple aggregations in flight, being closed all at once, they will naturally all have their own threads (coming from the last arriving message in each aggregation) so can be handled in parallel. We also have the Aggregation policy type which has a property controlling the "Number of timeout threads" which causes a separate sweeper thread pool to be assigned. Unfortunately the Collector node doesn't have the equivalent policy setting, and in any case this is currently a polocy property rather than a property on the message flow node itself. Given this slight difference with the stated aim we feel the suggestion should remain open at this review, but note that there has not been high demand in this area recently, which potentially could be due to the emergence of the newer Group nodes (which use in-memory queues rather than MQ for state storage). Status maintained for now as Future Consideration.

    Agreed - thanks for raising. We accept that allowing more control over the configuration of the event-driven architecture nodes is desirable for high volume scenarios.
