Re: [paho-dev] [m2m-iwg] Reference Implementation: MQTT Server in Java?

Both are great - the more implementations that work and interoperate, the better!

My understanding is that neither the Apollo implementation nor the backported version in ActiveMQ support bridging with other brokers like RSMB - and I've not played enough to know whether it supports dynamic topic creation, which I know is a limitation of the NirvanaMQ / myChannels implementation of MQTT. These are also obviously also multi-protocol products whereas mosquitto and RSMB "just" deliver simple, lightweight MQTT implementations.

I didn't think moquette was complete the last time I took a look at it.

I think if we want another broker, one as part of Paho, we should consider making it a solid reference implementation of the base protocol (plus the RSMB extensions to do the bridging, which apparently are not documented as part of the spec itself). 

If either of the others you've mentioned could be refactored in that direction and were in a position to be added to Eclipse then I'm sure we'd want to discuss that. I suspect the ActiveMQ options are not in that category due to the Apache license, but I'm personally really happy to see more implementations to give users more choice.

After some digging around it seems that there are some emerging solutions (thanks to @kartben for the info):
What do you guys think of these projects ?

Hi,

Feel free to comment / update / delete / add / whateveryouwant :)

I also add it under the "Project resources" of the Paho main page, but I don't think that is the right place...

Regards,
Nico

Agreed - please feel free to use the Eclipse Paho wiki for this discussion / design. I'm sure a lot of people would be keen to collaborate.

One slight challenge is the lack of a clear and certified spec for MQTT itself - new details such as extensions added for bridging, expected behaviour over dynamic topic creation, some clarifications around the published spec etc. have recently emerged via the mqtt Google Group, so you may want to take a look there too for additional background (these details have usually been added to the mqtt.org wiki as specification clarifications).

A clear, open reference implementation for a broker would be a very good thing indeed! :-) mosquitto is a good example, of course.

Great !

I'll try to setup a wiki page or something in order to share some ideas.

What I have in mind is something ligth and dedicated to MQTT, open source, embedable and two connectors : raw socket and websocket.

What do you guys think of such idea ?


I think this is absolutely wonderful idea. I would be willing to help as much as my very limited time would allow.
