Re: [mosquitto-dev] [paho-dev] Java MQTT broker

[Andrea Selva <selva.andre@xxxxxxxxx>]

Hi Ian,

moquette is is MQTT 3.1 compliant, but ha some part to be developer
better, for example it need a better implementation of QoS 1-2
messages handling. Moquette lacks an authentication mechanism (by now
there is just a dummy interface to be extended) but I expect to
introduce a plug system based on java's ServiceLocator APIs. Moquette
lacks also a mechanism to manage and monitor it (I'm thinking to
create some JMX stuff) and completely miss a configuration system (no
conf directory to fill with properties or xml files); so I expect to
be quite behind of Mosquitto.

 Also Moquette hasn't any documentation on google code, an area that
should be improved a lot.

On the architectural side, Moquette has a front Netty parsing library
that push MQTT decoded messages in a LMAX's magic ring buffer, the
protocol logic pulls out event from this queue and process them in
single threaded fashion ( a single thread event processor), than use
another ring buffer on the back to send out the MQTT messages (always
using Netty).

By now there is only me involved in the development, and usually I try
to handle the development in the evening or during spare weekends, I
know is not so much.

Ask me any question, I'll try to give you answers.

Best regards

  Andrea Selva
