title: Can MQTT broker be configured to send data to subscribers at a different rate?
body: <p>I am new to MQTT and working with the mosquitto broker and development libraries. </p>
  
  <p>I have a usecase where different subscribers may want to subscribe to a given topic but would want the data at different rates. So, subscriber1 may want it only on change from the previous value while subscriber2 may want it on a fixed cadence, say, every few mins/seconds.</p>
  
  <p>Is there a way to configure that in the mosquitto broker? Or any other broker that supports it?</p>
