:param sla: time by which the job is expected to succeed. Note that | |
this represents the ``timedelta`` after the period is closed. For | |
example if you set an SLA of 1 hour, the scheduler would send an email | |
soon after 1:00AM on the ``2016-01-02`` if the ``2016-01-01`` instance | |
has not succeeded yet. | |
The scheduler pays special attention for jobs with an SLA and | |
sends alert | |
emails for sla misses. SLA misses are also recorded in the database | |
for future reference. All tasks that share the same SLA time | |
get bundled in a single email, sent soon after that time. SLA | |
notification are sent once and only once for each task instance. | |
:type sla: datetime.timedelta | |
