Carsten Ziegeler commented on SLING-2979:
-----------------------------------------
I'Ve revised the implementation and changed the property to "scheduler.runOn"
which can either have
- a string (array) of Sling IDs where this job should run
- the constant LEADER - to run on the leader only
- the constant SINGLE - to run on a single instance only
> Add support for running scheduled task on specific instances

> Key: SLING-2979
> URL: https://issues.apache.org/jira/browse/SLING-2979
> Project: Sling
> Issue Type: New Feature
> Components: Commons
> Reporter: Carsten Ziegeler
> Assignee: Carsten Ziegeler
> Fix For: Commons Scheduler 2.4.0
>
>
> With the new topology api we have support for leader election. In many cases
> scheduled tasks should only run on a single instance in a cluster. So far
> this can only be done by manually adding the task through the Scheduler
> interface but not with the whiteboard support.
> We should add a new property scheduler.leaderonly which defaults to false but
> can be set to true. IN this case the task is only started on the leader.
