Hi ,
I am new to Mosquitto and have been reading about
mosquitto broker and MQTT broker for a couple of weeks.
It would be great if someone can answer my queries.
1. Is there any plugin available or in development,
which would store the messages received by the broker in
the configured database ? I know this can be done by a
client subscribing to all the topics and then persisting
it to database. But issues like what would happen If that
specific client connection got disconnected got me looking
for this kind of plugin. Something similar to
http://www.hivemq.com/plugin/mqtt-message-log/
2. How can I write my own plugin of mosquitto broker
? if at all that is possible now .
thanks in advance !

Hi Ravi
This topic has come up in the past. The consensus seems to be
that you take care of storing your own state data.
This can be done in a simple database using a MQTT small
client that subscribes to the topics you want to save; and to
requests to get a stored version of that data - performing a
subsequent database lookup and MQTT publish.
We are using Google's Level DB which has a simple key ->
value framework and ideally lends itself to storing topic ->
payload data.
