[jira] [Created] (KARAF-739) Provide a way to handle recurring
tasks in celllar
Provide a way to handle recurring tasks in celllar
--------------------------------------------------
Key: KARAF-739
URL: https://issues.apache.org/jira/browse/KARAF-739
Project: Karaf
Issue Type: New Feature
Components: cellar-core
Affects Versions: cellar-2.2.1, cellar-3.0.0
Reporter: Ioannis Canellos
Assignee: Ioannis Canellos
Priority: Minor
There are many cases that cellar requires the implementation of task that will be executed repeaditly (something like Timer/TimerTask). Especially tasks that are related to node discovery, ping etc.
What I imagine is an interface that describes the delay/period of the task and a service listener that wraps the service implementation in TimerTask.

--------------------------------------
I think the work should be the same independent where we place it, but it sounds quite useful to be reused somewhere else too. I just though about this because there is no "timer-namespace" replacement for Springs timer support in blueprint. So we may provide our own with Karaf (with the additional plus of being fully integrated into the karaf shell)

--------------------------------------
I think this could also be quite useful outside from celler. Maybe we could provide such functionality in a small util-bundle. That way such things could be used without cellar (and even withouth Karaf; I'm not sure that we have to integrate this lib deeply). WDYT?

Ioannis Canellos resolved KARAF-739.
------------------------------------
Resolution: Won't Fix
Since we pushed part of this functionality to Karaf trunk, we don't have to do it in Cellar too.

----------------------------------------
I agree with that. We could also build some shell commands around it (listing recurring services/period, canceling & rescheduling).

----------------------------------
Karaf can perhaps rely on cron expressions to designate frequency:

--------------------------------------------
As reminder, the requirement comes from the handling of network failure between Cellar nodes.
But Andreas is right, it could be interesting to have it in Karaf core.

--------------------------------------------
Yeah it's what I suggest on the mailing list.
By using Quartz (with the different kind of trigger and JobDataMap), I think that we cover a large part of our requirements.
