Setting the QoS flag <forceUpdate/> to false allows to suppress sending a published message to its subscribers when the content of this message didn't change from the former message.

Default is that identical published messages are sent to subscribers again.

Example
Java 
      
<qos>
   <!-- An update is forced even when the content and meta data didn't change -->
   <forceUpdate>true</forceUpdate>
</qos>
