 - `RepeatCount`: An optional value indicating how often the job should repeat
 - `DueTime`: An optional point in time representing either the one time when the job should execute (if not recurring)
 or the not-before time from which the schedule should take effect

+
+`failure_policy` specifies how the job should handle failures.
+
+It can be set to `constant` or `drop`.
+- The `constant` policy will retry the job up to `max_retries` times, with a delay of `interval` between retries.
+- The `drop` policy will drop the job after the first failure, without retrying.
