Customer Service subscribes to Order Created event
Order Service publishes Order Approved event
SqlTableBasedDuplicateMessageDetector in Customer Service records that Order Approved has been "processed" even though its ignored.
This happens because MessageConsumer subscribes to channels but DomainEventHandler is only interested in certain events within the channel.
This results in more DB inserts.
One solution would be for MessageHandler to implement boolean isInteresting(Message m) so that SqlTableBasedDuplicateMessageDetector can ignore boring messages.
