    Hi all,

    Any experience with using IBM MQ as an MQTT broker? Any view on limitations? Good/bad idea? 

    One of our customers is looking for an MQTT broker to handle IOT messsages. Volumes seem to be acceptable. A couple of 100 messages per second. 

    They have already IBM MQ so this was the first thing that came to mind ;-)

    Thanks for sharing your experience/thoughts. 

    PS: does MessageSight still exist? The appliance form? 

    have a nice day

    MQTT is designed just for that.  We are using the publish/subscribe features in production.  I did some testing- the throughput is amazing: One caveat - although the spec allows for some REALLY large messages(268435455 bytes approx 260MB), The key is to avoid setting the retained flag:   MQTT should not be used to store the information - just to subscribe/receive - publlsh wo retention.
