I am trying to use backpressure with the reactive client but it seems impossible. It’s so easy to use in Fusesource, to set a maximum send and receive value but I am absolutely not sure how to use sendMaximum and receiveMaximum in HiveMQ. I have read the other thread in this community, about backpressure support, but I still don’t understand how backpressure is supposed to work. Is there anyone here who can help me? Maybe there is some example I can use or someone who can give me some example code? I have used the example from the other thread, without any luck. The send- and receiveMaximum seems to have no effect at all.
