Subject RE: [Grouping][enhancing event definition] - group definition, groupId - adding group definition, instance Id to instance events
Date Sat, 15 Nov 2014 17:45:28 GMT
Actually I think
group type == group.name and group instance id == group.alias

Thanks

Martin

Subject: [Grouping][enhancing event definition] - group definition, groupId - adding group
definition, instance Id to instance events


In the grouping specification we also discussed adding a group definition and a group id to
the instance events (InstanceActivatedEvent, InstanceMaintenanceModeEvent, InstanceReadyToShutdownEvent,
InstanceStartedEvent).
The group definition would identify something like the group type (=== alias ?) and the group
id would allow to identify a group instance (of a specific group definition / type).

Examples: ,
+ scaling up multiple instances of a group, same group definition but different group instance
ids
+ A dependency becomes faulty which would for example require termination of all dependents
in the group (and subsequent groups if nested). Restoring the dependencies would also recreate
a new group of the same definition
but with new instance id (and subsequently the same would be the case for nested groups).

WDYT ?

Thanks

Martin
