This flag can be set when implementing background jobs to automatically deduplicate jobs when they are enqueued. If an unstarted job already exists in the queue the
enqueue()
fn will returnOk(None)
instead of the job ID.This should allow us to get rid of
enqueue_sync_to_index()
as a special case and make the same functionality available to other jobs as well.
