This read-only value, in seconds and defaulting to 60, reports the minimum time a completed, canceled, or aborted job's detailed attribute entries remain in the attribute table before removal. An admin uses it to know the window available for retrieving detailed per-job attribute data after job completion, distinct from the more general job-record persistence. For example, an attribute persistence of 60 seconds tells the admin any custom accounting attributes must be retrieved within that minute-long window.
