grouping support in CartridgeAgent
Hi Isuru,
To add initial support for grouping in the cartridge agent I suggest to add the following:
EventListener for GroupActivated, ApplicationCreated and ApplicationRemoved event (with respective support in ExtensionHandler), WDYT ?
Thanks
Martin

Hi Martin,
At the moment we are sending only the application id and group name to each
cluster instance as a part of the payload. As we progress, we will need to
add support for to process these events via extension handlers + add the
application id for events sent from the instance (InstanceActivated, etc.).
WDYT?

Rekha,
I am not entirely clear what kind of action the agent should / will perform when receiving application information ?
Once we know that we can decide which events should be handled, wdyt ? Do we need more input on this ?
Thanks
Martin

If it is GroupActivated, then can the cartridge agent only act upon the immediate group activation or does it need to all the ancestor's Group activation as well? Do we nee to listen on ApplicationCreated and ApplicationRemoved Event? Would cartridge agent capable of handling those events without properly parsing the dependency tree? But if the immediate parent is Application, then we may need Application events.
We have ClusterActivated as well. If we have an extension for it, then once the dependent cluster activated, relevant parameters can be used. wdyt?
Thanks

If it is GroupActivated, then can the cartridge agent only act upon the
immediate group activation or does it need to all the ancestor's Group
activation as well? Do we nee to listen on ApplicationCreated and
ApplicationRemoved Event? Would cartridge agent capable of handling those
events without properly parsing the dependency tree? But if the immediate
parent is Application, then we may need Application events.
We have ClusterActivated as well. If we have an extension for it, then once
the dependent cluster activated, relevant parameters can be used. wdyt?
