I have three computers that interact with each other using Open Splice DDS and I want to limit the total count of published instances. There are three publishers and the total count of published instances should not exceed 100. To achieve that, I set the topic qos as following:
The DDS specification addresses resource-limits 'per' reader/writer (and durability-service)so there's currently nothing to limited the 'total' count of published instances over a distributed system of multiple applications that contain multiple domainParticipants for multiple Topics..
If you'd want that you'd need to implement some sort of 'centralized claim-instance' service that you then should 'ask for permission' to publish yet another (unique) instance of a topic .
Furthermore, make sure that you're not confusing samples and instances as its a common mistake ..
