Re: [mosquitto-dev] Can you use mosquitto /mqtt to track changes in databases

Hi Marl

I've never tried this using MQTT, <but>, it should be possible to use MQTT paho lib as the communication medium between your mobile device(s) and the trigger-event system. One part will be to setup (pending on the database) triggers that "watch" for change(s) and inside the trigger you need to hook in your notification system sending a MQTT message....basic idea is - the database trigger and pub a message to say mosquitto - you have to thing carefully on how you going to use our topic's for this sort of "notifications" ....

I when work with topics I normally look at the end-point,...the system subscribing to topics...what will the application LISTEN for and what will it do with the in this instance, the mobile phone or desktop is the end point....

But I think it should be possible - you can even use the trigger on database side to drop the info in a Queue and get workers to pub MQTT message for people to all depends on what is possible on the database trigger side ;)

My 2 sent worth of option/input

Hope it helps a bit....

Hi. Has anyone tried using mqtt to track and share changes in a database?
specifically, when data in a database changes i would like to notify some interested parties, and provide a way for them to get at the data.
Is this possible using mqtt?
