[jira] [Commented] (SLING-3139) Provide a way to schedule jobs

["Carsten Ziegeler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-3139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13789190#comment-13789190 ] 

Carsten Ziegeler commented on SLING-3139:
-----------------------------------------

I've added a first api to the JobManager to create scheduled jobs, to query information about scheduled jobs and unschedule them

In addition I've added a method to stop a job, a job executor implementation can check periodically the context if it has been stopped and act accordingly.

Not sure if we need a maintenance queue as an ordered queue should do the trick as well

> The current way of scheduling jobs is not very user friendly: it requires to send an event via event admin. We should add a java api to create scheduled job creation.
> In addition, we could add a new queue type: maintenance queue which is an order queue with the difference of running jobs exactly at the point of time when they are created. So a scheduled maintenance job is executed exactly at the scheduled time - unless another job is currently running.
> Apart from starting such jobs, stopping a job would be another nice addition
