Maybe you can use the parameter server... "Nodes [...] communicate with one another using streaming topics, RPC services, and the Parameter Server."

EDIT: In order to mantain modularity and independent nodes, you can modify (increment?) a parameter '/pub_counter' everytime you publish on a topic. On the other side you can check this parameter within your callback function.
