Hi Lars We are looking at extending org.hisp.dhis.system.scheduling.Scheduler to also have the ability to return the ListenableFuture for a Runnable as well. This will help us or any dev in the future to check the status of the ongoing Runnables in the system and provide some user experience around it.
Please let know if you are ok with us taking it up? As we want to fix a bug wherein the "sync now" button should not be clickable if the task is already running.
