Re: [kapua-dev] service events code update (managing send error)
Hi Dejan, 
just a note about the house keeper since may be there’s a misunderstanding

In my implementation using the activemq virtual interceptor there is only one address queue for the outgoing messages (and this queue matches the microservice name) and there is a subscription queue for each service is subscribing that event.
The queue used by the housekeeper matches the correct microservice queue (since the housekeeper should republish the messages in the same microservice queue).
But this is just a virtual queue since the ActiveMQ doesn’t allow subscriptions for that queue, right?
Is that the internal queue are you telling about?

Hi guys,


here's the first PR that migrates this implementation to Artemis/Qpid JMS


It's just a first change, there's still more work to be done to finish it.

Give it a look.

I think house keeper job is not working at the moment (as I see that there's still a reference to the internal queues there). That's the first next thing I'd like to revisit.

Hi everyone,

I pushed changes to the https://github.com/stefanomorson/kapua/tree/feature-serviceEvents branch according to the suggestions coming from Dejan.

The event status has 3 state
- TRIGGERED (the event is triggered by the platform and inserted in the table)
- SEND_ERROR (the event message send operation was failed for some reason so the message wasn’t sent)
- SENT (the event message was correctly triggered and sent by the platform)

Now the HouseKeeper processes the events only if they:
- are in the SEND_ERROR state (so the event message send operation failed for some reason)
- are in a TRIGGERED status for a while (configurable via a configuration parameter)

Any feedbacks are welcome!
