[mosquitto-dev] Can multilpe data be send simeltanously to a same client

[Prajwal THAKUR <prajwalthakur98@xxxxxxxxx>]

Hi,
I have a scenario where msgs are generated, let's say 100ms and the latency in the system is 200ms. If I create a message at, let's say, T=0 sec and send it over the network, then it will take 200ms to receive the acknowledgment from the client. Can the broker process the other data generated at t=100ms and try to send it to the same client? (Or would it wait for the acknowledgment before processing the following message? In this case, it would be queued in some buffer, and the previous one would first be processed and then started processing this. ) I know in qos=0. This is possible, but I am unsure about the qos=1 and qos=2 mechanism. Do you know if there is any reference I can look into?
Thanks
