I'm not sure this statement is accurate. Certainly the MQTT broker I work on (IBM WIoTP Message Gateway) and a number of our competitors support QoS 2 in production (though I am aware a number of brokers don't support it).
- Arnavion 7y agoI imagine there are servers that drop QoS 1 or 2 messages that never complete the protocol after X amount of time, so that they don't keep consuming resources indefinitely. MQTT 5 standardizes this by adding a message expiry interval field, though even there it's opt-in by the publisher and defaults to forever.
