[jira] [Created] (SLING-3028) Support for progress tracking of jobs

Victor Saar created SLING-3028:
----------------------------------

             Summary: Support for progress tracking of jobs
                 Key: SLING-3028
                 URL: https://issues.apache.org/jira/browse/SLING-3028
             Project: Sling
          Issue Type: Improvement
          Components: Extensions
            Reporter: Victor Saar


For long-running jobs, it would be useful to have some means to track progress, which can be shown in a console for the user. This should include the following:

* ETA
* Completeness value computed from (optional, defaults to 1.0) max and current value (e.g. 42% or 23/100)
* Log output stream for detailed progress information
* Failure reason in case job failed

AFAICS this requires a few changes to the existing implementation:

* Jobs need additional support for setting properties, e.g. max and current progress value
* Jobs need to be kept at least for a while after they completed/failed to give access to failure information/log stream
