CRUD type events on ActiveMQ

ocox — Wed, 30 Sep 2020 06:18:31 GMT

Hi,

I'd like message notifiation of node events which I thought would be straightforward by listening to the ActiveMQ queue. But I can't find any information or documentation on this, does anyone have any experience or examples?

Thanks!

As far as I know alfresco community editon dose not support ActiveMQ to message queue yet.

Alfresco Community actually does support ActiveMQ for event processing, but as the original poster has noted, it is completely undocumented (even for Enterprise as far as I know), so barely any people are using it. Alfresco itself (in Community Edition as well as Enterprise) is the primary user of that functionality. E.g. the handling of thumbnail / rendition refresh after a content update is entirely based on the events queue since Alfresco 6.1, which is the reason that ActiveMQ is a technically required component in a Community deployment.

That sounds fairly promising though, thanks for the info. I've identified that Alfresco is using 5 different Alfresco topics:

ActiveMQ.Advisory.Consumer.Queue.acs-repo-transform-request
ActiveMQ.Advisory.Consumer.Queue.acs-repo-rendition-events
ActiveMQ.Advisory.MasterBroker
ActiveMQ.Advisory.Connection
ActiveMQ.Advisory.Queue

So I'll set a consumer on each of those and view the messages that arrive as I upload files to a folder. Do any examples or blogs spring to mind that might help?

Thanks,

Owen
