Subject [New Architecture] Topology Events Proposal - V1
Date Tue, 15 Oct 2013 05:22:38 GMT
Hi,

Please find the initial version of Topology Events Proposal below. These
events are added to org.apache.stratos.messaging component
org.apache.stratos.messaging.event.topology package.

Above events will be fired by Cloud Controller in the following manner:

1. Service Created Event
2. Cluster Created Event
3. Member Started Event
4. Member Activated Event
5. Member Suspended Event (Could trigger at any point after starting a
member)
6. Member Terminated Event (Could trigger at any point after starting a
member)
7. Cluster Removed Event (Could trigger at any point after creating a
cluster)
8. Service Removed Event (Could trigger at any point after creating a
service)
9. Complete Topology Event (Will be triggered periodically after tx time
period)

Please feel free to add your thoughts.

Note:
When we are introducing new events for other message broker topics, we
could add sub packages under org.apache.stratos.messaging.event with the
topic name.


Many Thanks
Imesh
