Re: [paho-dev] Critique of MQTT

[Ian Craggs <icraggs@xxxxxxxxxxxxxxxxxxxxxxx>]

David,

I agree.  I think *the* major strength of MQTT is its simplicity.   I can look at the specification or API and see quickly how I might implement it and use it.  As MQTT has capabilities added to it in future, I hope we are careful not to lose this strength.

It's often the constraints that make a system powerful. The history of computer systems is complicated powerful solutions for simpler constrained ones. Back in the day my VMS colleagues were on about how much better the modes the VMS file system provided were over UNIX's simplistic character mode. 

 

In the last year and half I've had to learn probably 30-50 new systems / technologies related to the IoT. I appreciate being able to pick up MQTT and be able to understand it[*] and use it in 30 minutes. Especially when that tech provides a solution for one of the biggest problems in APIs today.

You could spend a summer trying to figure out what the hell XMPP does for you.

Correct, I would also add that MQTT is being used in so many situations where nor the device neither the network is totally constrained (smartphones?) and so misunderstanding on intentions of specifications may arise.

Already seen here and on other MQTT-related lists: the protocol is a perfect fit when resources are limited, but it's so sexy in a number of different situations where the developer has a feeling of being too limited using such a simple and efficient protocol, and so demand for more features and complications arises.
